      Well once again I didn't know I had a problem till I read a message on this 
      list. The case of the broken rudder peddle, leaves me with a little concern. 
      Since I bought the airplane second hand I would not be on the normal mailing 
      list for AD's. Could someone please tell me what the Ad has to say. Leave me a
      
      message here or contact me directly at jperri(at)intersev.com

The problem was that the weld was not good enuf or strong enuf. The 'cure' is to weld a gusset to the front and back of the strap where it is welded to the tube. The gusset only needs to be about 1/2" long along the tube and 1" long on the strap. You can make these gussets out of 0.032" 4130. While you're doing this you might also want to use some of that 4130 to make a strap that will help strengthen the rudder vertical tube to cross-over tube weld. Wrap this strap from the back side of the vertical tube around the cross-over tube to the front side of the vertical tube. I had mine break at the weld so decided to strengthen it. Since you're going to have to remove the rudder controls you might as well go ahead and touch up this 'weak' point as well. If you have the new rudder pedals that are suspended from above all bets are off. I don't know of any problems with them.

From the Rocky Mountain RVator who obtained the article from th Van's Air Force, Tri-State Wing. "While having cocktails at Van's dinner at Oshkosh, I met a Canadian builder who had stumbled across what may be the neatest little light you ever saw. It is a GE 50 watt, 12 volt EXN Halogen Bulb with a built in flood reflector and glass cover that is designed for a track lighting system. It is 2" in diameter and 1 1/4" deep. The package says that the bulb is good for 5000 hours! It has two pins in the back of the bulb. I hooked one up to my battery charger, and it draws 3 amps and provides a light so broght that if you look at it you will have a big blind spot for several minutes! If you have any doubts about whether this bulb will stand up to the rigors of flight, let me relate to yu what our Maple Leaf friend did to test the light. First, he let it cold soak over night at -5 degrees and then lit it up with a battery charger. Then he mounted it on a compressor that had a lot of vibration and let the light burn for several days. Next, he mounted them on his car grill and used them like headlights. It turned out that they were much brighter than the ar's headlights on high beam! Convinced, he decided that they would work as landing lights and will make fabricating a mounting bracket easy, and the lens is completely sealed, including a front lens cover. They are so small that a very tiny hole in the wing leading edge or wing tip can be used for a landing light. Wal Mart had the GE bulb for $ 9.95 and an equivalent generic bulb for $ 3.95, altough the generic bulb doesn't say anything about expected service life. Since I already installed on of Duckwork's landing lights in my wing, I plan to install one in the cowl to burn all the time as a recognition light. By the way, if you ahve the Cuckworks landing light and want to put a 100 watt bulb in to get more light, Wal Mart wells a GE Halogen H3-100 that is an exact match for the lower wattage bulb Don provides. It is much cheaper, too." Ther you go--- Bob Skinner ________________________________________________________________________________

Subject: Fuel Dump for RV6 Tanks
I'm near on to starting on the fuel tanks on my RVA and thought I would share a thought thats been mulling over in my mind for a couple years now. If I'm over an area where there is no 'easy' landing when the engine decides to go nite-nite. One the largest thoughts at that time has to be "Why is all this fuel next to me going down with me" One of the next thoughts has to be "Why the heck didn't I figure out a way to get rid of it when I was sitting at home thinking about it last year" Seems like I shouldn't be the only person to ever think there should be a very quick way to dump fuel overboard in an emergency. (for small planes I mean). Has any of our bright guys or gals out there ever read about solutions to this. I would be interested in any comments or ideas.

Seems to me that regardless of the inflight difficulty, with FEW exceptions, it would be preferable to keep the volatile avgas contained. What if, when you attempt to dump, static electricity ignites the fuel leaving the aircraft? What if all the fuel you want to leave the aircraft has not exhausted itself prior to landing and/or impact? In either scenario, not good. Fuel dumping certification criteria for turbine powered aircraft is quite detailed, and JET-A is not as volitile as avgas. IMO, I'd keep the avgas onboard.

Subject: Fwd Fuselage Belly Skin ?s
Forward bottom skin on the RV-6 ...... Spent the better part of the day today installing the F-672 forward bottom skin. A few months back I remember reading about some of the rivets working loose in this area (especially on the 180hp airplanes). I've outlined our modifications below and am asking the group if what we did is enough to keep us from experiencing these same problems (we're going with 160hp). Still time to make changes, so will take any and all inputs from you. 1. Used 1/8" rivets along firewall stiffener with 1" spacing (plans call for 3/32" with 1.25 spacing). 2. Used 1" spacing on floor stiffeners, 1st two rivets 1/8", remaining 3/32" as per Frank Justice (plans call for 3/32 with 1.25" spacing). We stayed with 3/32" rivets; we were paranoid of drilling out too much metal with the 1/8" rivets at 1" spacing (although we did do that on the firewall stiffener). There's one more mod we've thought about making, but need some advice before pressing on. The center bottom skins (F-676/677) extend far enough forward (overlapping the F-672 forward bottom skin) that a THIRD row of rivets could be placed directly underneath the spar. Here's the problem ... best we can measure, it looks like we'll ONLY have between 1/8" and 3/16" clearance between the skins and where the spar will rest. An eighth of an inch is plenty of room for the shop head on a 3/32" rivet, but what kind of problems will we introduce when it comes time to insert the spar into the fuselage? Is there any benefit to adding this third row of rivets, or should we just hack off the center bottom skins at the trailing edge of the spar as per the plans? Questions for things we still have to do on the forward bottom skin... 1. Do we dimple or countersink the F/604 bulkhead flange when installing the skins? If you say dimple, can I do that with a hand squeezer? 2. Frank Justice suggests leaving the forward bottom skin off until the instruments have been installed. We've been told that skin should be riveted in place to give the forward fuselage some rigidity after removal from the jig. Our "informant" claims that there is more than enough access from above if the top skin is left off until the instruments are in place. Anybody with experience using either of the above methods? 3. Where on the firewall should proseal/RTV be used when riveting the skins to the firewall ... all the way around, just the bottom/corners? Thanks for all your help in advance. Mark G.

Check the regs on nav lt installation, for viewing degrees required. Putting them on the wingtip without a bump doesn't satisfy the feds, tho they might not catch it at inspection. I've installed several sets of nav lts, all but one under the Van's lenses. The remaining set was under the lenses sold by Chief Aircraft. IMHO, the Chief set is a better looking installation. Also, there is room for a strobe piggyback unit under these lenses. Unfortunately, these are currently out of production. You'll still have to make a bracket to set the lt. so it's visible from the correct angles if you use the Van's lens.

This would If you mount them flush to the wingtips you may not get them sighted from above, they could be blanked by the edge of the tip. Most folk here make a mounting pad from hard foam, so the light is mounted vertically, an dbeyond the edge of the wingtip.

Subject: Quick Build Kits on the way
Taken from Western Flyer, December 1995. Newsletter of West Australian Division, Sport Aircraft Association of Australia,. Editor Graham Taylor, E-mail: gmt(at)perth.DIALix.oz.au . Two months ago it was reported in this column (in Western Flyer) that Kevin Wintergreen had been talking to Van about the ease of construction with the prepunched wing skins. Van's response was "You haven't seen anything yet". It can now be revealed just what he meant by that enigmatic remark. As luck would have it Tom Krieg's (Perth T18 builder/flyer) brother was in Kuala Lumpur when the following announcement appeared in the New Straits Times on Saturday 21 October 1995. US AIRCRAFT KITS TO BE ASSEMBLED HERE. By Sabry Sharif and Adrian David. KUALA LUMPUR Fri. Phileo Aviation (Malaysia) Sdn Bhd will assemble airframe parts of the RV6A leisure and recreational aeroplane on behalf of its United States based manufacturer, Van's Aircraft Inc, a company official said today. "Under a buy-back agreement, the quick-build kits will be re-exported to the US principal" said Phileo Aviation Director Tong Kooi Ong. Although the recently set up company was confident of a market for the aircraft here, its obligation for the next two years was "to ensure a steady supply of the kits to Van's Aircraft in Portland, Oregon" he said. He added Phileo Aviation understood the manpower constraints in aircraft manufacturing and assembly particularly in Malaysia. "However, we do not anticipate such problems with the RV6A parts and components assembly at a rented factory near the Glenmarie-Hicom Industrial Park (in Subang)", said Tong. In a media briefing at Shangri-La Hotel here, Tong, who is also the man behind Phileo Allied Berhad, the financial services and property group, said the assembly plant would concentrate on putting together the fuselage, wings and tail. "These parts account for 49 percent of the aircraft. The engine, avionics and other parts of the aircraft will be manufactured and assembled in the US together with our kits", he said. Phileo Aviation will have an initial staff of 35 to assemble parts for five aircraft a month, before gradually increasing capacity to 20 a month by the first year and 40 by end of 1996, with staff strength then increasing to 100. Tong hoped to start assembly of the kits by early next year. "In the US, the kits will be marketed to Do It Yourself enthusiasts who will complete the remaining 51 percent assembly process, involving such fittings as the engine, propeller, undercarriage and avionics". He added there was a demand for the quick-build kits as the assembly time now averaging between 2,000 and 3,000 man- hours would be reduced to about 800. The kit alone will cost US$11,000 while the whole builtup aircraft can cost anything from US$20,000. The 49-51 percent breakdown is a mandatory requirement under the Federal Aviation Administration regulations for experimental aircraft. Being classified as a kit-plane, the manufacturer is allowed to build up to 49 percent of the aircraft only. Tong said the RV series had proven to be popular with flying enthusiasts in the US, Europe and Australia, where special packages involving pilot training, aircraft maintenance and parking facilities are included for the aircraft buyer. Under the second phase targeted in mid 1996, Tong said they would expand into marketing the quick-build kits and completely builtup (CBU) units locally. "Phileo Aviation has the exclusive marketing rights for the CBU in Malaysia and is negotiating with Van's Aircraft for similar rights in other Asian markets", he said. Also present were Phileo Aviation directors Rudy Koh Eng Wah, who is also Phileo Allied Berhad Executive Director, Ahmad Abdullah, General Manager, Alan K.S. Foo and Assistant General Manager Dr Lim Kong Loong. Asked for his rationale for getting involved in an industry with a long repayment period on investments, Tong said it would help the nation further develop its aerospace industry and establish Malaysia as a regional base for the manufacture and marketing of small aircraft. He also said the company was impressed with the technical performance and affordability of the RV6A. "It is safe, cheap, and easy to maintain, which are important if you want to sell such aircraft overseas and here", he added. More than 5,000 RVs, including some 500 RV6As have been sold in the US alone. The first model of the aircraft, the RV1, designed by former US Air Force officer Richard Van Grunsven, flew in 1965. Van Grunsven, who went on to develop the RV2, RV3, RV4 and RV6 models, is currently developing the RV8. Tong said the RV6A, the top end of the RV range, has enough power and manoeuvrability to do basic aerobatics. The aircraft can also take off from, and land on, less developed or rugged airstrips, and has short field capability. The RV6A is powered by a single 160 hp Lycoming O-320 engine, has a gross weight of 1,650 lb (about 750 kg), cruises at 299km per hour and has a range of 1,216 km. Phileo Aviation will next month bring two RV6As for aerial and static demonstrations at the Langkawi International Maritime and Aerospace (LIMA) '95 exhibition on Dec 5 -10. END OF NEWSPAPER ARTICLE. Bill Benedict from Vans was in Perth just before Christmas, and he was surprised we knew about the Malaysian deal. I thought others would be too.

Subject: When Did You Become An RV Builder?
When did you consider yourself an RV builder? Was it the first time you saw one on the flightline or in a magazine? Was it when you ordered your first info kit and video? The plans? The first kit? Was it when you bent that first piece of metal, or skinned that first knuckle? Completed that first component? Or was it when you finally got signed-off for your first flight? This is a really big project, but like a headache, it's difficult to say sometimes when it really starts or when it really ends. I've seen a lot of homebuilt airplanes. But I've *never* seen one that was done! Someone is always thinking about a better radio, or another carpet color, or an additional fuel tank or something. But when did it start, for you? And what was the one biggest factor, in your decision to build an RV?

Subject: Manual Elevator Trim on RV-6
Hello from South Carolina! Hope everyone survived the Christmas rush. I'm still working on the trim tab on my RV-6. I have the manual trim, and I am concerned about slop in the cable. Right before Christmas, Jerry Springer responded to Scott in Chicago: >I flew for over 400 hrs with the manual trim and did not like it because of the >slack that was in the cable. I installed a Mac trim and have over 300 hrs on >it and find that it works great, I have the switch on the control stick and I >find that it is much easier to trim now...... I also have some play in the cable (about 1/8"), and I wonder how aggravating that will actually be in flight. Won't aerodynamic loads on the tail keep the slack taken up? What about the possibility of trim tab flutter? Is anybody else happy (or unhappy) with the manual system? I really want to keep everything as simple and reliable as possible, but it also has to be functional. If there is a compelling reason for the electric trim (other than the obvious "coolness" factor) please let me know.

Conversion looked messy so I asked Van about it when he was in Australia in March. His advice was that manual has no problems, but to convert, leave the elevator setup as for manual, use an RV4 throttle cable to run back to the servo mounted behind F606 bulkhead. This gets rid of the 180 degree bend which is the cause of the slop Bill Benedict was in Sydney a couple of weeks ago. He is confident that mechanical has no problems. I have flown in two RV6s which seem to have no problems, but Simon Pike's second RV6 (with all the "wish I hadda" items included) has electric. You choose!

Since the two HS Spar flanges are a butt splice there you won't lose any appreciatble strength by notching the flanges; of course, I assume you would only be notching for about 1 to 1 1/2" out from the splice.

I guess I considered myself a builder when I finished my first component, the HS. That was quite thrill. Sorta like a first solo. The biggest factor in my decision to build one was (and this in Vans buzzword, but it's a fact) the value. It represented the most airplane (IMHO) that I could buy for the money.

I'll admit that there are times when I see an ad for the Lancair 4P that I think " It'd sure be cool to be able to cruise @ 335 MPH and almost 30,000 feet !" , but then I start thinking about all the negatives : - Alot of extra build time. (I heard of one glass plane the builder spent 9000 hours on!) - Alot of extra maintenance.(Especially with turbocharger) - Alot of extra runway. - Alot of extra money. - Fussier building environment requirement. - Fears of delamination.

Subject: I bought an engine
Well, everyone, I just had to share this. Yesterday I bought an engine. I found a used IO320-B1A. It's runout, at the end of it's second run. The logbook shows that at the last overhaul the crank had not been ground and was still a standard crank. The engine was pulled out of a twin Comanche at TBO for a 180hp conversion. It is a complete 'firewall forward' engine (I even have the old Comanche engine mount), with all accessories (even the oil cooler and baffling!), and cost me $4500. In a few weeks, I'll tear it down and send the crankshaft out for inspection (and cross my fingers). A couple of notes for anyone else considering an IO320-B1A: These engines have the Bendix fuel injection servo mounted on the aft face of the sump. IN order to fit easily, you need to swap the sump for one that mounts the servo on the bottom. My local parts supplier says he can find a sump for me for about $250. Second, not only is it a Dynafocal 2 mount, the mounting surfaces have recessed notches that require the use of aluminum spacers to provide crankcase clearance for the dynafocal shocks. (Fortunately for me this was not a problem, since my engine came with the old engine mount, the spacers and old dynafocal shocks were still in place.) Before I bought this engine, I called Van's and talked to Tom. I asked him if there was anything else that was special about this engine I should worry about, and he said no. So now that I've got an engine, I think I'll go ahead and reserve an N-number and get the (future) airplane registered. How does N601DB sound? :-) Best Regards, Dave Barnhart rv-6 sn 23744 ________________________________________________________________________________

First up, congratulations to "DB" on getting his engine.... I just wanted to let you fellow listers know that I have installed an 0-320 with the curved riser in my "6A" - this was not supposed to be a possibility according to factory info. The engine is a 1956 vintage 0320 - (no suffix on the plate or in the logbook so I guess its an A1A?) - conical mount, from a mooney M20. - I expected to have to convert the sump to a straight riser when I bought it... but the price was right...(3000tt, 800smoh) - $6000 including C/S prop, all accessories including the governor. I even managed to use the standard air box from Vans, but I did need to make a new top plate to move the box further forward away from the nose wheel mount - the filter is now a pretty tight fit... I also had to modify the rig to make the fibrglass bowl detachable to allow easier maintenance - . It's pretty close but I have about 1/4" between the airbox and the gear mount. I will be happy to give further details to anyone who has a similar situation.... All the best for a safe and prosperous new year to all RVators - especially Lancastrians !!!! ;^) Rob Lee ________________________________________________________________________________

Subject: Drill Bushing -Spar & Rib Reinforcing Angle Brackets
What did you use as a drill bushing for the 3/16 diameter holes in the spar where the AN bolts attach the rib reinforcing angles? The plans recommend using a bushing so as not to enlarge the factory drilled holes in the spar. This drilling step is where the rib reinforcing angles (Rib Attach Angles W-630) are clamped in place on the spar and 2 holes for the AN bolts are drilled into the rib reinforcing angles using the existing holes in the main spare as a guide. I am not familiar with bushings. Are they available at a hardware store? Did you not use a bushing but drilled carefully?

Subject: Extra Row of Rivets ...
.... on the F-672 (RV-6) forward bottom skin. I need some advice before pressing on. The center bottom skins (F-676/677) extend far enough forward (overlapping the F-672 forward bottom skin) that a THIRD row of rivets could be placed directly underneath the spar. Here's the problem ... best I can measure, it looks like I'll ONLY have between 1/8" and 3/16" clearance between the skins and where the spar will rest. An eighth of an inch is plenty of room for the shop head on a 3/32" rivet, but what kind of problems will be introduced when it comes time to insert the spar into the fuselage? Is there any benefit to adding this third row of rivets, or should I just hack off the center bottom skins at the trailing edge of the spar as per the plans? Mark G.

I just got my RV-4 flying. I found that most of the 'slop' in the trim tab was due to the clevis pins and not the cable. I removed the pins and used AN-3 bolts and this got rid of most of the slop.

I do not have a strong opinion on this, but I did install a parking brake (and dual brakes) on my 6A. My resoning was that it is much more convenient than lugging chocks around when you are fueling or whatever on your own. Or indeed when just popping into the FBO to answer natures call! The park brake wasn't too complicated, and used the existing hoses from Vans. I used the Cleveland parking brake valve which I got from Aircraft Spruce. It mounted on the inside of the firewall, directly above the pilots feet, and just below the top upper angle. Cable comes out on the extreme LHS of the panel. The only additional thing needed was about 18" more 1/4" alum. tube.- John, From your other posting I presume you are a Lanky too ? Details ?

Subject: Explosion while priming ?
Preface: I have heard of a few stories of people blowing themselves up when pouring gasoline from cans into airplanes and lawnmowers (via static electricity sparks). My local FBO always grounds the airplane before he fills it. Yet I have never seen anybody ground their lawnmower when they fill it. In light of reasonable safety, what do you think of the following questions regarding the potential of explosion from priming? (Note: up to this point I have been priming with Tempo zinc chromate cans and have not given it a second thought. However, I am switching to a spray gun today for the wing spars.) Most metal spray guns I have seen contain the warning on the side of the spray head that says 'do not use glass jars'. Does this have anything to do with the fact that glass is not a conductor, and there could be a differential electrostatic charge between the paint in the glass conatainer and the metal spray gun (potentially causing and explosion)? Or does it only have to do with the fact that glass jars can break in the spray gun - jar attach neck. I have purchased one of those paint zip guns that works by syphoning to variprime my parts. I noticed that the paint only flows through plastic parts and is stored in paper cups. Couldn't there still be an electrostatic potential between the paint and the metal being painted? Does anybody out their go to the trouble of grounding their paint sprayers and parts their spraying? The paper cups fall off the zip gun so I took a small glass jar with a metal cup lid and riveted to the zip gun. Is this safe considering the above? Why do they sell the zip gun with wax cups when I have read previously the wax comes off the cup and ends up on the primed surface? Thanks in advance to all the people who shed some light on this ...

The wing is heavy and awkward enough when inserting into the fuse. with out having the additional problem of hanging up on rivets that shouldn't be there. The rivets could also remove primer off of the bottom of your spar and in fact, gouge the metal. I figure there are enough rivets to drive without addiding additional ones.

I purchased a small touch-up gun ( they can be found in various catalogs) for about $ 20-30 and they do a much better job. I haven't worried much about explosion from static electricy.

Go to your hardware store or hobby shop and buy brass tubing.

(for the 1/4 in the main spar, use a 1/8 inner dia. tube). Cut the tubing to about 1.5" lengths, stack together, push in the hole and drill.

Yes it does complicate the lines, especially if you have dual brakes. I just finished my changeover to dual brakes with parking brake. I mounted the valve (from Spruce) on the firewall and a push/pull cable on the panel to set/release it. I used the high pressure plastic tubing from Van for everything inside the fuselage except the input to the valve where you must transition to aluminum lines and AN hardware. I used heavy duty airbrake fittings on all the plastic. These have the insert attached, and a special ferrule which provides a superior seal. It was difficult to push the hose on to the attached insert in the confined spaces under the panel so I broke off the inserts and instead used hardware store inserts which fit tightly into the plastic. I used my flush rivet set (in the gun) to tap them into the hose. Speaking of brakes, after about 200 hours my AL lines broke at the fitting on the caliper assembly. I had provided the relief Van has recommended in the construction plans. They apparently work hardened from the vibration. This time I'll transition to a flex hose (aircraft type) about 6 inches from the caliper.

How does one countersink the wing skins where they overlap the spars = (main and rear) and the tank baffle? The way I see it I have at least = three options: 1) Machine countersink the skins (not my first choice). 2) Dimple the skin and the spar/baffle (I think the material is too = thick to dimple). 3) Dimple the skin and countersink the spar/baffle. (I'm not excited = about taking material out of the spar). What's the preferred method here? Thanks. ________________________________________________________________________________

How many times have you noticed (or been involved) when there is a radio mis-communication between aircraft or aircraft/controllers due to poorly enunciated call signs, and/or bad radios or reception? Choosing easily said and understood numerics and alphabetics can help this problem. I personally favor 4 character call signs if you can get them, since it's less tempting to truncate during an exchange with a controller. "Fiver" , "niner" , and "zero" also are particularly hard to distort. I also like the two syllable alphabetics. Just my opinion. As you are probably aware, you will be allowed to list several choices in rank order. Congratulations on your engine! Can you use a carb or fuel injection on the existing sump? You could take the scoop off the cowl and cut your drag. There might be enough clearance with the mount, etc. Nose gear could complicate it tho.

I live just off exit 189 in Everett and this is about 45-50 miles north of where Boeing surplus is. I believe the 188 referred to in the above message is the street number and not the exit number. You can get to Boeing surplus one of two ways: Take exit 152 off of I-5 and head east. The road winds down the hill to the valley floor and then heads straight across the valley. Turn left on 84th and left again at the first light which will put you in the parking lot for the surplus store. A second way is to get on I-405 and take the highway 167 exit. I am not sure of the exit number but it must be exit 2 or 3. Head south on 167 and take the exit for 212th street. Take a right on 212th (heading west) and then a right on to 84th. Again, a left at the light puts you in the parking lot. I stopped there just before the Christmas break and bought two vixen files for a total of $4.00 and two rivet sets for about $4.00. Both rivet sets have a slight angle near the tip and look alot like the EXTRA LONG BACK RIVETING SET as shown on page 29 in Avery's 95 catalog. I took the longer one (about 10 inches long) into work and worked with our model shop to mill the rivet cup flat. I plan to use it for backriveting my top main skins on my wing. You can never predict what you will find there, but I (and my family) always enjoy going there and will usually try to fit it in if we are going past during their open hours. Happy shopping!

Subject: How do HVLP systems work?
How do the "turbine" HVLP systems work? Campbell Hausfeld sells an HVLP system, in which a single hose runs to the gun. I'm presuming that paint is supplied to the gun under high pressure through this hose, and atomization occurs when it is squirted out through a fine tip. Is this the same technique used in the Croix system? I get the impression the answer is no, since a blurb I saw on the Croix specified something like "90 CFM @ 5 PSI". This implies to me something akin to a centrifugal blower inside the box (the "turbine"?). I also heard that Eagle makes a nice HVLP system that comes with the Accuspray gun, reputed to be the best HVLP gun in the business. What makes these things work (besides money)? Do they work well? Any experience with C-H, Croix or Eagle? Can anyone help me sort all this out?

I don't think you want to counter sink any of these pieces!! If I recall correctly, you can dimple all the parts you listed. I think if you check, you will find the nut plates that are to be used here are the type that go under a dimpled skin as they have the large depression in them (not flat as used on C/S skins). You can dimple the spar flange just fine, esp with a pneumatic dimpler. The only special tool you may need is the 'pop rivet dimpler' from Avery. You need this on a few of the holes on the spar flange close to the wing root due to the thickness of all the spar strips in that area. I just finished assemblying and flying my RV/4 and I recall noting all the rivets around the tank and spar were dimpled.

> > > How do the "turbine" HVLP systems work? The turbine is like a fan and blows a lot of air, but without developing much pressure. Since there isn't a big blast of pressurized air, there isn't much overspray. Conventional guns end up with about 50% paint on project and 50% overspray. HVLP it's more like 90/10 when they are used correctly. There is nothing wrong with a turbine setup. However, you have to buy a turbine. Another option (since most of us already own a compressor) is to buy an HVLP gun which runs off a compressor. The special HVLP gun will convert high pressure low volume to high volume low pressure at the gun; I don't really know the details of how it works, but the result is you end up with a HVLP setup off your compressor. I have a Binks Mach 1. It's supposed to be one of the best HVLP's. It's expensive at $300 plus cup and/or pressure pot; I chose a pressure (not siphon) cup ($100) and a pressure pot ($90 for cheap one). It works fine. Although it's expensive, it's still cheaper than the turbine route. > > Campbell Hausfeld sells an HVLP system, in which a single hose runs to > the gun.

A side tube from the main airway provides some pressure to the paint can forcing paint out the needle valve at the front of the gun. Air jets at the sides of the needle valve atomize the paint stream and carry material to the surface. There is less overspray than with the conventional airless I used to use. With my Campbell-Hausfield I have to over-thin regular alkyd enamels to avoid a pebbled texture. No idea how it would spray materials you'll need to use.

Access is easy through removable wingtips. I don't have details but could provide if anyone is interested. Three flying RVs (2-6's and 1-6A) are having difficulty getting their units to track on the centerline. They all report off center tracking. All three also reported unexplained radical turns requiring the immediate decoupling of the units. One builder has installed a disconnect switch right above the throttle for easy access. Anyone else experience this?? I noticed in the recent postings that one person had to change the GPS to 1/10 th of a mile from 4/10's and another said they had to be within 2-3 degrees of course to start tracking. Two of the flying RV's also reported that the airplane must be retrimmed after disengaging the unit. Some of the recent posting seem to alude to the fact that their installations did not require this. What did you do to prevent this??? Does Navaid have any competetors (price/value/reliability)???

Brian, there are two types of HVLP systems. The 'turbine' type (like Croix) and the other type just uses a regular air compressor with a HVLP spray gun. I think the EPA rules and California laws have forced most spray gun makers to go to HVLP guns. I think the Campbell Hausfeld HVLP gun you refered to is of this later type and the single hose is just the air hose (does not carry fluid). I just painted my plane and I looked into a number of these guns. Most of the HVLP guns that you can use with your regular air compressor are designed to use more volume and lower pressures. I ended up buying a Sharp HVLP gravity feed gun and used it with my 2 HP compressor. It did have less overspray. I like the gravity feed as you can use all the paint in the container (the cup is on top of the gun). You can now get HVLP in all three types of guns, gravity feed, suction cup, and pressure feed. I decided to stay away from pressure feed as you waste a lot of paint to fill up the hose and you use a lot of cleaner to clean up the hose and gun. From what I found, the German made 'Sata' guns are the most expensive and highest quality. There are several Japanese guns also. The Sharp gun lists for $250 and I got it for 210. In summary, you can now get HVLP guns from all the major paint gun vendors. Most of these work with your regular air compressor. By the way, I was steered away from the Accuspray gun as the expert I talke with here at Austin Laquer said they had some design problems with the gun. I don't recall the details now. They may have fixed the problems by now. Herman > > How do the "turbine" HVLP systems work? > > Campbell Hausfeld sells an HVLP system, in which a single hose runs to > the gun.

Subject: More Pre-punching...
Happy New Year All! I spoke with Van's before the holidays and it appears the direction is to offer more "pre-punched" skins in the RV kits. I was told that in the near future the tail kit will be sold with pre-punched skins. I asked how the holes are punched. They said that it is done with a "punch press" and is fairly impressive operation to watch it work. It actually moves the whole piece of metal around on a table rather than moving the punch. It is supposed to run at a fairly high speed. Van's currently has a third party perfomring the punching since "punch presses" are expensive. The Vans representative said they are looking into buying a machine since they will be punching the tail kit in the near future. This whole subject was started since I believe there is an error in the plans in the Vertical Stabilizer dimensions. Using the formula a squared+ b squared = c squared for triangles it appears that the 11 1/8 dimension shown near the tip rib may be in error. It caused me to have a difficult time getting the skin overhand on the spar at this end when the 82.5 degree angle is properly achieved. This will all be history when the tail skins are shipped pre-punched. fyi, John Hovan hovan(at)apple.com http://atlantis.austin.apple.com/people.pages/jhovan/home.html ________________________________________________________________________________

Is this safe considering the above? I don't think there's any potential danger with paint guns, I think it has to do with gasoline being FAR more volatile than primer. However, I don't know why the mfgr reccomends against glass containers. I too, had trouble with cups coming off of the zipgun (which is one of my favorite tools) I found that the reason the cup comes off is because of the gun deforming the lip of the cup when you press it on. Press the cup on, then rotate it 20 degrees or so. Now the ears will be holding "virgin" cup rim and won't fall off. As for the waxed cups - use 'em for coffee but not for painting. That primer is pretty acidic and will eat some of that wax into the primer (quite a conflict of interest). The wax also comes off and clogs the opening of the nozzle. I found a great cup locally; it's a Solo #116FS (it's got "french fries" written on the outside) No wax, and it works great. I think it may be a little deeper too, but it has the same mouth diameter. -- Ed Bundy ________________________________________________________________________________

I bought it after seeing the demonstration at Oshkosh a couple of times. I only had a 2 hp compressor and didn't want to spend the big bucks for one large enough to run a spray gun continously. Also, the 110 volt aspect appealed to me as I intended to primer and paint my house, so I thought that I could spread the cost over many different jobs. I also intended to restore a 1972 Pontiac Grand Prix the we bought new ($ 4,540.00) but decided I'd rather build another new RV than restore an old car. I also painted an old steam locomotive for the county hisorical society (they're a lot bigger than they look). There are a lot of home projects you can use it on and it is very portable. I've been mostly satisfied with the Croix although the Accuspray gun looks easier to clean. You do save a noticible amount of paint and there is very little overspray in the air. I primed the inside of the RV and finished the instrument panel and all visible surfaces in the cabin. I had a professional painter (who happened to use a Croix) paint the outside (I helped on the prep work). After painting the inside of the RV I decided that the way I mess around, I'd better have a pro paint it or it would be another 3 years before I got it flying. We painted when it was 90-95 degrees and used the warmest weather reducer that PPG made. The paint did have some orange peel. It was not real bad and I've had a lot of compliments on the paint job, but if you look closely, you can see it (especially under florescent lights) The painter said to bring it back after it cured and he would rub it out. I've heard from others that the HVLP will orange peel quicker than a conventional spray gun. The turbine tend to heat the air and I mentioned to my painter that perhaps additonal lengths of hose coiled in a 50 drum full of cool water might drop the temp and help the paint flow out a little better. I'd be interested in hearing from anyone who was able to put down a finish that flowed out properly. Perhaps another paint system would work out better. I used PPG Durethaned on DP epoxy primer. Another advantage to the HVLP with a turbine (they make HVLP guns that use conventional air) is you don't have to worry about oil contamination in your air line.

Subject: Re: Notching HS Flange So Elevator Control Horn Can Move
Just mounted my HS on fuselage last night... which brought back memories of asking myself the same question about notching the aft edges of the h.s. spar channel to get the required 30 degrees of up travel. Yes, I did notch my channel edge (only about 1/8" cut out) where the elevator horns hit the channel... but certainly NOT the reinforcement flanges themselves, which lie inside the spar channel. Never-the-less, here are some tips I would like to pass on: 1. Be sure you are measuring angular deflection of the elevator center-line... NOT the angle of the elevator skin surface (makes a big difference!). Here's where an electronic level (e.g., "Smart Level") is useful... as you can simply add the starting angle of the elevator surface to the total deflection angle of the surface in the down position. 2. If you are just starting on the HS, look carefully at picture #4 on page 6-29 of the construction manual (andat plans sheet #34)... notice the two holes in each end of the horiz. surface of the 1 X 1" angle in the picture, these holes are used to bolt the front spars of the HS to the fuselage longerons. So... don't get carried away in cutting and filing away the horiz. face of this angle (which you do to allow bending the vertical faces so they will mate with the front HS spar channels). I did... and filed away extra metal (to be "sure" to avoid stress fractures when bending the vertical faces)... metal I wish was still there now, as I only have minimal edge clearance for the AN3 bolts that attach the ends of this angle to the longerons. As described in a recent RVator... you can make up a doubler, if you end up without enough edge clearance. In my case, I gained some extra edge clearance by mounting my HS 1/8" farther aft on the fuselage than planned (and adding 1/8" plate spacers behind the rear HS spar attach flanges). This worked out fine... although, I did have to file about 1/8" off the aft edges of my elevator horns... again to get the full 30 degrees of "up" travel. Yet another lesson in the saying that "every minor change from the plans generates three more down the line".

Re: Your questions about Eaglespray HVLP system. I purchased an Eaglespray unit with the Accuspray gun (the gun was rated a top design achievement by Popular Science magazine in 1993, I believe). I bought it through Mel Turcanik from a Sport Aviation ad, and he offered a discount to EAA members. I have been very pleased with its performance to date. I have only primed with it so far (both Variprime and PPG DP-48) and have had excellent results. Cleaning the gun is about on a par with conventional spray equipment. Scott McDaniel in Phoenix painted his very nice RV-6A using a Croix HVLP ( owned by the Arizona council of EAA Chapters) and PPG paint and got excellent results. If you don't already have the big compressor needed for the good HVLP guns, the turbine systems are a good choice, but they are not cheap - figure $600-700. Hope this helps.

There is no mention as to where 3/32 stop and 1/8 start. I went ahead and made ALL 1/8. Is this OK? Couldn't resist doing a test fit of the right wing into the fuselage last night.

You'll find that it's OD is 3/16". Cut to the length that you need, even solder/weld a handle on it, then drill out to #30 using a long drill bit. The result is a neat sleave that you can put thru the spar and sparbox to drill the lading gear attachments. You can also use a long flexible #30 drill bit when drilling these holes without worrying about bit alignment.

The "Aeronautical (formerly "Airmans") Information Manual" has a nice write-up on radio communications, phraseology and techniques, including correct phonetic pronunciation. Also mentioned there is a note that you may omit the word "experimental" after initial callup. Here in Austin, our controllers have a list of "common" experimentals, including 16 types, 4 of which are our RV's.

This was done by bringing the low pressure side of the brake pistons up to a tee, then feeding it into the resivor. Given this type of setup, it should be possible to put a parking brake piston (single) in the feed line from the resivor. Any comments on this approach?

Subject: Question for RV-6 builders
I've got a question for the 6 builders. How does Van recommend you terminate the brake line at the caliper? Does he suggest going all the way to the caliper with AL tube or using a small piece of flex between the caliper and AL tube? I decided to use AL tube and have already run it inside my fiberglass gear leg farings to the caliper; after hearing of the break in the tube the other day on the net I've been trying to decide if I should go ahead and replace the tube and use flex at the bottom. This would mean cutting the farings but... TIA Dan Boudro RV-4 N9167Z ________________________________________________________________________________

Item Subject: cc:Mail Text Hi gang; here's my first real builder's question: Starting my HS spar. One of my 409s fit into the 603 channels just fine, but the other one is way off, no matter how I try it. Comparing the two 409s, they're nowhere near the same shape. My friend's 409s are identical. If I have one side against the flange, the other end is at least 1/8" away from the flange. I emailed Van's, and Tom said to just cleco the center in, bend the ends so they're flush against the flange, and keep drilling/clecoing outward. The pre-load should have no effect. I suppose I might try it, but the question is: would you? Maybe I'm being too anal about this, but I don't want to be worring about it for the rest of my life.

Steve: I probably would send it back and get another part, or else grind it to fit, assuming you don't have to remove too much mat'l. It's easy for me to say "I'd get a new part" since I live close to Van's though.... I had something similar happen to me with a wing LE skin -- the bend at the nose was off by at least 1/2" and I really had to work to force the skin to conform to the ribs. I talked to Tom about this and he showed me a stack of LE skins that were bent exactly the same and said if I REALLY wanted they could bend another one special for me (although I'll bet they went back and changed the way they bent them after I brought it to their attention). Anyhow, he convinced me to just use it and said it would be fine. So I did and made it work but I kind of wished I had insisted -- it just didn't sit right with me forcing parts into shape that much. Also especially this early in your project, you want things to be RIGHT. That's my two cents worth anyhow.

Subject: IFR flight in our homebuilts
I've just started my IFR training, and I've started to think about the equipment I want to put in my 6A's panel when it becomes time. I want to be able to fly IFR approaches. In order to fly IFR in our airplanes, does anyone know how much of our equipment must be TSO'd for IFR flight? We experimenters get away with installing a lot of non-TSO'd equipment. One of the big questions -- if I install a non-TSO'd GPS, can I do GPS approaches? What if I install a TSO'd GPS, but install it myself? (I understand production airplanes must have their installation performed my an approved-for-IFR-installation shop.) Does anyone understand why a GPS that is TSO'd for IFR is so expensive? Is it the certification process that's expensive, or is the actual box that much more capable? -J -- Joe Larson ________________________________________________________________________________

Subject: Fuel Tank Slosh Removal
Hi all, About 3 weeks after I finished the left fuel tank, Van's came out with the recommendation not to use slosh any more on the fuel tanks due to several instances of chunks peeling off. I made the bold decision then not to do anything until I got ready to rivet the right tank. Well, that time is just about here. I think I will try to open the hummer up by cutting access holes in the rear baffle on each bay, somehow cleaning out the lovingly applied slosh, and then closing the thing back up. A few questions: 1. How do I get the inevitable metal shavings that will be generated out of the tank? 2. What is the best way of removing the slosh? I know the part about "Pour in a gallon of and shake it all about" but how about some real world experience about what happens when you do this? What is left after the solvent is poured off? How do you remove the residue? Paper towels? Rags? ScotchBrite? Hammer and chisel? Will there be any suprises? How long do you have to get the crud out after soaking with solvent (I assume I'll want to do the solvent bit before cutting open gapping holes in the back)? How do you pour out the old solvent without having a toxic waste emergency response team sent out to your house? 3. Is making an .040 reinforcing ring for the outside of the baffle ok (the ring on the normal opening is on the inside)? 4. Are the same pop rivets used for attaching the rear baffle to the ribs ok for attaching the cover, or is something stronger (screws?) more appropriate? 5. Any other sage advise? I may end up calling Van's anyway to discuss this, but I was hoping I could get a few real-world-war-stories before venturing off into the unknown. I know some folks have had good luck removing the whole rear baffle, but I kind of like the idea of (relatively) easily removable access covers in case I ever need to get into the thing in the future. I'll build those into the right tank up front, I guess... The feeling of delight after getting the left tank "done" and tested was oh so short...

If you did a good job of prep work, you might get by fine. I talked to a couple of RV "gurus" that had worked on leaking tanks and they indicated that the slosh had disappeared after a period of time. It didn't sheet off, just evidently eroded (mechanicly or chemically) away. As far as chemical to use to remove slosh, I'd worry about any chemical action on the proseal, as well. I'd recommend not cutting the access holes until you have a problem. It'd be a shame if later, your tanks didn't leak, but your access holes did and by not cutting them now, you would speed construction along. In other words, don't cut them until you have a problem because you might not have a problem. If you decide to go ahead, I'd recommend the pop rivets as a bunch of screws is just another source of possible leaks and construction time is longer. I used the white slosh and have 196 hrs on my RV-6 since Feb. 95 and have not had any problems so far. (But like every one else, I have my fingers crossed.) I'm building a 6-A now and won't be using slosh. Good luck, Bob Skinner ________________________________________________________________________________

The pre-load should have no effect. I had the same thing happen to me. I didn't talk to Van's but I ended up doing what Tom suggested to you. In my case, the pre-load *did* have an effect. When I removed the completed spar from the jig, it had a curve to it. When I stretched a string from one end to the other, the center line where the 603's came together was off by about 1/8" (it was straight when I drilled it on the jig). Probably not enough to matter, but it bugged me. Because of the misalignment and the fact that I drilled the holes for the center bracket the wrong size, I ended up reordering the two 603's and 409's. The second time around, I did not have to bend the 409's to get them to conform to the 603 channels and the spar came out perfectly straight. ------ Russell Neeper Texas A&M University russell(at)net.tamu.edu Computing & Information Services RV6a #22884 - working on the ailerons. ________________________________________________________________________________

Subject: Re: RV-List- IFR flight in o
Reply to: RE>RV-List: IFR flight in our homebuilts The "experimental" category pertains to your airframe and engine only. It has nothing to do with the instrument panel. To fly in IMC or "on instruments" you must meet all applicable FAR's just as in a certified aircraft. That is, all "primary" flight instruments must be TSO'd, dated, signed-off, calibrated etc... "Secondary" instruments (those not essential to the safety of the flight) are not required to be certified or meet instrument calibration dates. Example, if you are performing a non-precision, VOR approach and happen to use a hand-held, moving map, non-tso, or other type of GPS for "situational awareness!" you should be ok. However, if your VOR's FAILED during the flight and you relied on the non-cert GPS you would be illegal. Your burden would be to prove that all PRIMARY (minimum equipment instruments) were functional BEFORE take-off and that they subsequently failed during the flight. Not only are you putting human life at unnecessary risk but the cost of legal representation will be greater than if you bought a tso'd GPS in the first place! The extra cost is due, in part, to the paper trail for certified parts but, in some cases, improved technology. Certified GPS units MUST announce a system failure if it occurs (your hand-held doesn't have to). I don't know about mean-time-before-failure but if the certified unit has a higher MTFB than a non-cert unit that would account for the expense of better parts. Certainly the mfgr is exposed to greater liability - so you know part of the cost is for that insurance premium to pay the lawyers!

I had the same situation and same worries (longer ago than I care to admit, given where I am today...) so I called Van's and happened to get Van himself. He said it was no problem at all, just to hold the edges tight against the spar flange while drilling. He explained that the little bit of pre-load was insignificant, and that the distortion of the parts was the result of the heat treating process. I found when doing this step that the force required to hold the parts tight to the flange was really quite small. At least that's my best recollection of what transpired... yikes... that was almost 4 years ago!

Joe: As a Canadian, I don't know much about the FAA's requirements for equipment. But I think you need to consider whether you _want_ to shoot approaches with non-TSO'd equipment. It's TSO'd for a reason. Perhaps someone out there can correct me if I'm wrong, but I think one of the requirements for TSO'd GPS units is that there is some way to determine if unit is receiving bad information. VORs are self-checking; if one starts to send an erroneous signal it shuts itself down. If you're on approach when that happens, you lose the signal, overshoot, and you're safe. If you're on approach and you start getting bad GPS data, and the unit has no way of checking that, you won't know that something has gone wrong. That's not a situation I'd feel comfortable with, even if it were legal.

There are several classes of TSO for IFR certified GPS units pertaining to the type of operation. Basically there are 3 defined approaches, Overlay Supplemental (traditional approach equipment must be on board), Overlay Standalone (Only after 1997 when the Wide Area Augmentation System arrives), and Standalone (there are less than ten of these existing now). A signal testing technology called RAIM is used in IFR GPS's. I am not sure its required for all approaches but certainly is for Standalone. As you mentioned, certified a/c must obtain a 337 including a test flight. Then it is legal only if the database if current. Handhelds do not qualify.

Subject: Is it in yet?
Okay, somebody just mentioned trial fitting their wing to an RV-6 fuselage and said it fit like it was supposed to. (???) I just trial fitted one of my RV-4 wings to my fuselage as well. While it was gratifying to see the main spar did in fact fit, I was mildly surprised by how tight the fit was (I built my carrythrough bulkhead around the spars before building the wings or fuselage, so I know the carrythrough structure and spars were matched). The question is: Is this tight fit typical? I mean TIGHT - to get the wing out I had to drive the spar out with a piece of wood and a heavy hammer. Are there any techniques out there to loosen up the fit (if this is even desireable) or special methods developed to insert and remove the main spars?

Subject: Re: VStab, to offset or not?
Began mounting my VS to the fuselage tonight (yes, got the HS mounted to my satisfaction last night... sigh of relief). This brings up the question of whether to offset the leading edge of the VS to compensate for the rotation of the air flow across the tail due to the effect of the prop. If so, how much? And in which direction? Opinions/Pireps? Thanks in advance, John Pallister p.s.- Found an easy way to check that the VS was mounted vertically. First, level the fuselage. Then, run a plumb bob line down the center holes of the three hinge mounts on the aft surface of the VS (assumes your VS was built straignt). Adjust to center the plumb line, clamp & drill. p.p.s. Also, caught myself about to use AN3 bolts instead of AN4's in the 3 holes that secure the base of the VS to the fuselage and tail wheel mount. (An easy mistake to make, after using AN3's in the upper mount holes, and a bunch of AN3's to mount the HS). (Wonder how many of you are going to go out and look to see if you did the same?)

Same problem here couple years ago. I also did what Tom said.

It did not. I carefully drilled and riveted. The spar came out perfectly straight.

Oops, sorry about the blank message. I routed (or tried to, anyway) the pitot line in the left wing last night and it's left me with some questions. 1) Did everyone/anyone use a single piece of AL tubing from the end of the spar to the L fitting in the leading edge? Seems like it'll be tough to replace if something breaks. I considered using soft tubing under the tank, and it's not too late to change it. 2) Is some kind of support for the tubing required behind the fuel tank? It seems like a long run for the tubing with no support, but I'm not sure what I'd use. 3) How does the line get from behind the tank outside the former (F-405) to inside the fuselage? If anyone's got any other suggestions I'd appreciate them. This stuff is either not on the plans (MY version, anyway) or I just can't find it.

INstead of using aluminum tubing, I used polyflo. I've had a lot better luck keeping the nylon fittings from leaking than I have with the standard AN fittings. Besides, I don't have to worry about making a bunch of bends in the tubing where it goes from in front of the spar through the lightning hole and connects to the pitot tube. As for securing the tubing behind the tank, the plans show fabricating a couple of little clamps and pop-riveting them down. If you use polyflo, I'd suggest that you use some groomstrip (sometimes called 'caterpiller') around the edge of the lightning hole in the spar where the polyflo passes thru (for abrasion protection). You'll also need a couple of extra fittings at the pitot tube, since nylon flair fittings seem to be unavailable.

I have been using PPG DX 1791 self etching primer on my wings. I like the way it goes on and the slight brass/gold color once it is dried. This week I went back to my PPG paint store and the seemingly knowledgeable salesman told be that the DX 1791 was not very good for corrosion protection and that their best product was DP 48/50 (number depends on the color, available in five colors). He convinced me to go with the DP 50 rather than the DX 1791. A question for those that know or use PPG products, just how corrosion proof is the self etching primer, and should I go over the wing areas that are metal to metal with the DP 50? I have already primed the entire wing with DX 1791. I am worried about weight, but then again, I do not want a rusty wing if I should move to the Florida Keys! Another primer question. What is faying, and what should be used to protect against it. Will a good primer solve this problem?

Date: Jan 04, 1996
I thought thats what she said :). I just assembled my RV4 and the wings slid in with very little force required. When you build the fuselage, you need to keep spacers (wood blocks) between the carrythrough bulkheads so that the spacing is maintained when you are riveting on things like the floor ribs and such which attach to this carrythrouh structure. Failure to do this may alter the dimensions some and cause it to be too tight. All you can do at this poing is spray the spars with silicone or oil when you go to insert them. You may also look to see if you caused some problem with the floor ribs or the two ribs that go forward to the firewall. As long as you can get them in (even with some force) is all that matters as they will probably never be taken out again.

Hi All, One thing that I have come across is that drilling or riveting parts "under stresses," as would be necessary in the procedure above, can cause twists in the final part as Russell states above. These twists can form in the vertical and horizontal planes! I used 6 plumb lines to ensure that the twists did not impact the HS. For the horizontal plane, the procedure for locating the fabricated brackets removes horizontal twists in the spar. Here's how I tried to ensure there were no vertical twists. Put two nails into the side posts of the jig about a foot higher than the tallest HS skeleton rib. Run a heavy piece of string or fishing line across the jig and attatch to the nails. (The string is parallel to the cross beam of the jig) Next, about 2" away on the string (measured from the post), hang a plumb line that reaches the horizontal centerline of the jig cross beam. Bend the nails to center it perfectly. Perform the same procedure on the other side of the jig. This ensures that the sting is exactly parallel to the centerline of the rear spar. Then, simply tie plumb lines as needed to the horizontal string across the jig. I aligned them so that they hung 1/4" from each tip rib. Then the ribs can be adjusted so that they are on the centerline. Remember to check the centerline on the jig cross beam so that it is exactly the same as the centerline of the rear spar when it is mounted in the jig. If not, make adjustments to the procedure above so that the string follows the spar centerline. Also...As Tony Bingelis once told me, "The centerline is your best friend!" So, be sure that it is accurately drawn and measured both on the jig and spar to allow the above procedure to work properly. enjoy, John hovan(at)apple.com http://atlantis.austin.apple.com/people.pages/jhovan/home.html ________________________________________________________________________________

It runs from a heated AN pitot tube located just outside of the second to the last wing rib just behind the spar. Yup, it's way out there like a Piper installation to keep it away from the aileron bellcrank and tie down rope. It wouldn't fit in the location suggested in the plans. The tube runs through grommets installed in the wing ribs behind the spar, then makes a jog through a spar lightening hole before reaching the aileron bellcrank (I don't remember exactly which station), and then the routing is completed per Van's recommended path for the -6 with little clamps pop-riveted to the spar web which holds the tank. As I was almost done closing my wings, I realized that I'd forgotten to route this line but I was still able to do so with some trouble. The line is not long enough to extend all the way to the panel so I intend to install a coupler somewhere near the root.

Yes, I did notch my channel edge (only about 1/8" cut out) where the elevator horns hit the channel... but certainly NOT the reinforcement flanges themselves, which lie inside the spar channel. (ADDITION: LATER REALIZED THAT I WAS MEASURING DEFLECTION OF THE ELEVATOR SURFACE AND NOT THE CENTERLINE... WHEN I WENT BACK AND MEASURED CENTERLINE DEFLECTION, I DISCOVERED THAT LITTLE IF ANY NOTCHING WAS REQUIRED (SEE #1 BELOW). Never-the-less, here are some tips I would like to pass on: 1. Be sure you are measuring angular deflection of the elevator center-line... NOT the angle of the elevator skin surface (makes a big difference!). Here's where an electronic level (e.g., "Smart Level") is useful... as you can simply add the starting angle of the elevator surface to the total deflection angle of the surface in the down position. 2. If you are just starting on the HS, look carefully at picture #4 on page 6-29 of the construction manual (and at plans sheet #34)... notice the two holes in each end of the horiz. surface of the 1 X 1" angle in the picture, these holes are used to bolt the front spars of the HS to the fuselage longerons. So... don't get carried away in cutting and filing away the horiz. face of this angle (which you do to allow bending the vertical faces so they will mate with the front HS spar channels). I did... and filed away extra metal (to be "sure" to avoid stress fractures when bending the vertical faces)... metal I wish was still there now, as I only have minimal edge clearance for the AN3 bolts that attach the ends of this angle to the longerons. As described in a recent RVator... you can make up a doubler, if you end up without enough edge clearance. In my case, I gained some extra edge clearance by mounting my HS 1/8" farther aft on the fuselage than planned (and adding 1/8" plate spacers behind the rear HS spar attach flanges). This worked out fine... although, I did have to file about 1/8" off the aft edges of my elevator horns... again to get the full 30 degrees of "up" travel. Yet another lesson in the saying that "every minor change from the plans generates three more down the line". NEW: 3. When drilling/riviting the aft fuselage deck to the longerons, do not drill any holes in the last 1" of the deck/longeron join. This is where you will bolt a piece of 3/4 X 3/4 X 1/8 angle to attach the longerons to the vertical stab spar. Or, I suppose you could carefully lay out the piece of angle (with aft, vertical surface parallel to the web of F612 and checked for plumb with the lower part of the web) and pilot drill the bolt holes. 4. One question that I wondered about for months: whether to trim the extra 1" or so off the aft ends of the longerons, where they extend beyond F612... was finally answered when I mounted the VS. The answer is yes. Not only did I trim them off flush with the aft edges of the F612 flanges, but I also trimmed the horizontal surface of the angles back to flush with the F612 web plane (left the vertical surfaces extending the extra 1/2" or so to end at the F612 flange edges. This allowed adding one final aft skin rivit. Visualize fitting the VS spar extension into the aft end of the fuselage to fit flush with the F612 web and you should get the mental picture. Trimming turned out to be easier that I had feared- used a 24 tooth jigsaw blade, and filed to fit. (Incidentally, if you have not yet discovered chainsaw sharpening round files, they are great for rapid cutting of radius corners!) Bottom line... doesn't hurt to leave 'em long till ready to mount the VS... it is an easy trim-to-fit job.

Subject: Re: VStab, to offset or not?
Springs might be a solution. Once had a C177 that was slightly misrigged so that it liked to roll left at cruise... a simple fix was to hang an extra headset on the right side of the passenger's control yoke. I bought my RV6 kit before the change to overhead rudder pedals, so still had the idea of rudder pedal springs to keep the pedals upright in mind... so, when installing the overhead pedal upgrade... I went ahead and added a couple of tabs for springs (thinking that they might be useful just to keep slack out of the cables). Did not occur to me that a little differential spring tension might also serve as rudder trim... hmmmm... Yet, it seems to me that trim tabs have a distinct advantage over springs... the greater the airspeed, the greater the force applied by a tab.... whereas, spring tension would be constant, and given no foot pressure, would produce more deflection at slower speeds... so you might find that ideal spring tension for cruise is overkill at slower speeds. I'm tending to think that it makes the most sense to "build it straight" (no offset), and add a trim wedge to the rudder, if necessary.

Date: Jan 04, 1996
> Could someone familiar with landing in that white fluffy stuff describe a > few things for me. Steve: When I was with the Canadian air force I flew Twin Otters on skis. I can answer your questions from that perspective, but some things might not apply to light aircraft. > 1. Can a tri-gear (rv6a) be fitted with skiis? Well, a Twin Otter is trigear, and it works great on skis. With trigear in fresh snow, it's very important to "drag" yourself a runway with several passes. We generally did one pass on the mains at just below flying speed, followed by one or two more passes on the mains bed in the tracks, followed by a pass with the nose gear on the snow, and finally the landing. The first pass is the most critical, of course, because that's your "runway", so you want it to be straight and into the wind. We also use to taxi through a "dog-bone" turn at each end before stopping, so we had nice turn-arounds. Some of this might be overkill for a lighter airplane (our gross weight was 14,000 lb). > 2. What condition does the snow have to be in to land? Can you land in > waist deep powder? (more than once :) We landed in some pretty deep snow. I've heard of people landing in waist deep, but I've never done it myself. There's quite a variety of snow types, and of course depth is only one variable. I had a "moment" once landing in snow that was about two feet deep: I let the mains pop out of the track I had dragged, and with the extra drag we could only accelerate to about 5 or 10 knots below T-O speed, even at max torque. We blasted down the lake for about a mile or two that way until we ran into a spot where the wind shifted and picked up a bit. Turning into the stronger headwind gave us enough lift to rise out of the snow a bit a pick up enough speed to start planing and accelerating, and eventually take off. One problem with an RV might be prop clearance. If the snow is deep, your nose gear is going to sink in a bit, and you could be stirring snow with the prop. I have no idea what the implications of that would be, but I suppose they could be serious if you sunk in enough. > 3. How flat does the surface need to be? Is relatively flat good enough, or > do small bumps cause huge problems? Is it common to look down and say, > "that looks like a good spot." Or is it more of a check with the locals to > see where is safe enough. I guess that depends a lot on your gear, and the size of plane. I would think that, with an RV, you'd want a pretty smooth surface. Depending on the snow, the bumps can be either soft or hard. Soft is better . Most lake surfaces are as smooth as a slightly whoopy grass strip, and the snow does cushion the shock loads somewhat. I wouldn't even think of ski flying in a new area without at least discussing it with experienced local pilots. There are too many variables, many of which are not visible from the air. > 4. Why do I ask?

Or am I > being un-realistic. I'm planning to do the same sort of thing with my RV-6 when it's done. To be honest, I think the tail dragger is probably a much better configuration for that sort of work. If there's a lake there, reliably frozen, that's likely to be your best option. I don't know what part of the world you're in. Around here (Alberta, Canada), the lakes are pretty reliable for about four or five months of the year. I've never landed on snow that wasn't on a lake or a runway, but I can imagine a lot of potential hazards, mostly from nasty things hidden under the snow (fences, tree stumps, that sort of thing). You need to consider a lot of things you might not consider in non-ski flying. Off the top of my head: - snow and ice in the controls - different flight plan considerations (flight itinerary vs. flight plan) - cold starting - fuel planning (it's probably not available where you're going) - weather (what's going to happen while your plane is parked on the snow--will be buried, will it get stuck, will you have VFR conditions when it's time to go home) - reasonable winter survival gear and knowledge if you plan to land away from civilization (a good idea even if you don't _plan_ to land away from civilization) - make damn sure your ELT works On the positive side, ski flying is tons of fun. The first time I flew on skis I had to keep telling myself it was legal, because it's so much fun it feels like it shouldn't be! Good luck.

In Europe I have seen exactly what you described but never, never in America. I have also seen hang gliders, ultralights and parasails operate right off of the slopes. The only place I know that allows hang gliding in the US is at Telluride and then you have to be an employee of the ski corporation. Now that many private airstrips will not let you land because of liability, I think you would cause quite a commotion when landing your RV at a ski resort. Don't forget a ski resort in the winter has big mountains with a lot of real tricky air, clouds, fog and ice fog. However the angle fire ski resort in NM is about 1/2 mile from the lifts, and if the runway is plowed you won't need skis! Good luck. Let us know what resorts you are thinking of trying this at.

I just painted my RV4 and had the same concern. I decided to use SS screws and painted most of the items seperatly and then installed with the SS screws. Note that most of these screws are structural type screws (have an x on the head) so you need to order the proper SS screws. I got mine from Alexander however I later found a note in the RVator that Van's sells these now as well (and lower cost of course). What I painted seperate (no screws) was the wing tanks, the top cover over the inst. panel, the various insp. covers and fairings. The only problem I have found is that if a screw does not go into the panel perfectly straight (90 degrees to the surface) then this puts a stress point on the paint area under the screw head and it will tend to wrinkle the paint under the head. This is typically not a problem but I had a few screws on that panel that covers all the instruments and a few of the screws that go into the firewall area were not square and cut into the paint. I used SS Tinnerman washers under the screws where ever fiberglass was used, like the Spinner, wheel pants, and fairings. I also used #6 SS screws to hold on the fiberglass wingtips. You can use an elect. drill/screwdriver to drive the screws in but I stop short and hand tighten them the final turn or so.

Subject: Re: Is it in yet?
Thanks to those who responded to my questions about tight fitting spars. Since I sent the mesage I called Van's and talked to Tom. He said the important concern was whether you could get the spars in. He recommended the use of 2-3 guys at the wingtip to wiggle/manuver the wing in and 2-3 more at the fuselage to stabilize it and keep it from shifting. I did this with just myself and my wife (5'2", but mean when she needs to be); getting the wing in was not a big problem, but she could not keep the fuselage from moving when I pulled on the wing. Tom also recommended the use of dry lubricant (graphite-effective but messy) or talcum powder (easily cleaned off later); not recommended was oil (could attract dirt, leading to galling) or WD-40 (evaporates too quickly - okay on the way in but not on the way out). I also asked about methods to "loosen" the fit; he said they had not yet had a person with a spar that wouldn't fit. To correct such a problem would entail removing the rivets from one side of the carrythrough bulkhead, inserting a spacer to get the proper clearance, and then re-riveting the bulkhead, redrilling and using oversize rivets as required. Obviously a lot of work, with a risk of misaligning something with the structure out of the jig. Incidently, I did use a spacer in the carrythrough slot when building the fuselage in the jig. It was 1-7/32" thick as specified in the RV-4 manual. Tom said 1-1/4" spacers would not be a bad idea, allowing that 1/32" for any slop. Hope this is helpful to anyone else sweating out the fit of their wings.

I worried that the pressure of the screws on the paint in the dimples would cause the paint to buckle. I have seen this on other airplanes. I had one or two that did chip a little and I touched them up with a fine artist brush. Thought about the fuel tanks for a long time before I painted them in case the tank(s) might leak.

My wings and tail are both 95% complete and the fuselage skelaton is riveted up and the skins are just now going on. Not too shabby since I got my wing kit only 8-1/2 months ago. I'm shooting to have it flying by OSH, with or with-out paint. With a goal like this I'll at least get it in the air before bad weather moves in next fall. I'm planning on an O-320 (just located one), basic flight instruments, Grand Rapids engine monitoring system (any one with experience with it?), com, nav, GPS and of coarse a CD player. I'm a Mechanical Engineer for a semi-trailer manuf. so alum. and rivet construction is a pcs of cake but the engine and systems will be a challenging experience that I'm looking forward to. I have just mailed the first edition of the "INDIANA RV BUILDERS NEWSLETTER" for which I am the editor. I hope that it will allow more of us RVators in the Hoosier state to get together.

My lofty goals for the -6 includes trips to New Orleans (I can taste the food now), the west coast and Alaska (hopefully with 2 or 3 friends who have a similar dream). Otherwise I would like to use it to go to skydiving drop zones around the Midwests. Keep on building/flying FS ________________________________________________________________________________

After waiting nearly 3 months for my heated pitot tube from Wicks (they did have the cheapest price) I now am looking for some advice from those of you who have installed these things (the standard Piper type). My questions are these: 1. Does anyone have plans for a mount for this thing? I saw on John Hovan's home page an ad for one that costs about $100 but I'd sure like to make my own if possible and save some money. 2. Mine came with an oval steel tube that appears as if it should slip over the vertical part of the tube. Is this supposed to be used as part of the mount? 3. Van's plans show that the tube should be mounted 6"-7" below the wing. Have those of you who installed heated ones adhered to this dimension? Since the vertical dimension of the tube itself is only about 3.5", it seems to me that this means I'd need an unusually long extension on my mount. I don't recall the Cherokee's I learned to fly in having the pitots hanging this far below the wing. 4. What length wire did you use when you soldered it to the "plug" that attaches to the pitot tube, enough to reach all the way to the instrument panel or just enough to reach to some intermediate point where you made a second connection? 5. Where did you actually mount the tube, in what rib bay and where in relation to the spar? I'd appreciate answers to any or all of these questions either to the list or to me personally.

Hi, Just back from my Christmas/New Year vacation, I see there have been a few postings concerning the rudder pedal 'AD' mentioned in my intro. It was actually a 'Mandatory change notice' from Vans dated 5. Sept 1990 (even published in RVator Sept 1990). As pointed out in some of the postings, it is about adding gussets to the floor mounted pedal tube/arm. New to me, though, was the failure of the pedal itself. It is a well proven design that should be sufficient in normal use. I am sure Van's will come up with a fix if considered necessary. I'll keep an eye on it anyway. Thank you for the information.

Subject: HVLP systems...
Thanks to everyone who replied to my question on HVLP systems. Your responses clarified things tremendously. What confused me is a Campbell Haudfeld system I thought was an HVLP system, but is not (at least in the true sense). It is a gun without a cup, that is supplied paint under pressure through the hose. No air is involved. As such, it is more akin to the Wagner Power Painter family of products, and is probably better suited for shooting heavy-bodied latex paints at things like houses than polyurethanes at airplanes. -Brian ----------------------------------------------------------------------- Brian Yablon Position: Hardware Engineer LANart Corporation Internet: byablon(at)lanart.com 145 Rosemary Street, Suite D1 Ma-bell: (617) 444-1994 x206 Needham, MA 02194 FAX: (617) 444-3692 LANart: Difference by Design ----------------------------------------------------------------------- ________________________________________________________________________________

Last winter I did some skiing in Switzerland and sure enough, people doing exactly what they want (parasail, hang gliding etc.) The ski area I had in mind is in Oregon. Mt.

Now I practice the sport of 'lawn-darting'. :( I think putting skiis on the rv to get close to a ski resort is more of a novelty. Not saying it wouldn't be a blast, but I think with the restrictions and so forth, it would be more trouble than it's worth just to taxi up to the resort.

About twenty years ago when stationed in Alaska we used to fly our R/C models off of the snow. All the club members agreed, flying off of snow was much more preferable than flying off of our dirt/cinder surface. What I learned was that the landings were just beautiful, no bounces and you never could tell exactly when the plane touched down. But on the down side if there was some obstruction in the snow, like a foot print or car tracks, you really could do some serious damage to the landing gear. Also we discovered that putting skis on a conventional gear was pretty straight forward, however the ski on the nose wheel (weenie wheel) was just courting disaster. The rigging and the maintenace ware unbelievable, even for an R/C model!! When using tricyle gear, we always had steerable nose wheel skis, not sure how to maneuver on the ground without a steerable nose wheel ski for a tricyle gear aircraft. If you are going fast enough, the rudder will help some, depending on the snow conditions, ruts, ice and wind. If it is a strong wind you are doomed to takiing into the wind, or sailing the A/C like you would do for floats. Taildraggers did not seem to have as much problem taxiing and turning on the snow. One thing to keep in mind is that the skis become shock absorbers, they must have some flexibility and should not be rigidly mounted to the A/C. Either the 94 or 95 Vans calendar had a picture of an RV-4 on skiis. It looked to me like it was designed with a lot of flexibility in the landing and flying wires. The depth of the snow that you can land in is determined by how long and wide the skis are. The plane will float on top of the snow if the ski surface area keeps the pounds/square foot loading light enough. While in Alaska I knew of many bush pilots that landed in snow too deep for them to take off. The solution is to dig out the snow shoes and pack down the runway! For two people this is about an eight hour job for a piper cub! Bob Busick RV-6 ________________________________________________________________________________

I think you should consider a little ski flying just for its own sake. It is a blast (although I'm speaking out of turn a little, never having done it in an RV; maybe it's a pain in the neck, but I doubt it). I hope to put skis on, fly north to a secluded lake, and do a little xc skiing, backcounty skiing, or snowshoeing, and maybe camp overnight.

I used laquer, and there was less overspray from the Accuspray gun than with a can of spray paint! I did not have to spend alot of time wet sanding the laquer and it had less orange peel than the factory finish had. The air from the turbine is warm, and OIL FREE, a distinct advantage over the regular compressor. I plan on using it on my RV when I get to that stage.

Subject: Tips
RVer's---Bad day for flying or building (-18 deg. f this a.m.) so am doing some computer work today. Been reading through the archive files for entertainment and enlightenment and keeping in the spirit of helping fellow RVer's thought that I'd pass along some tips that maybe you can use. I'm working on my second RV now. Got 196 hrs. on the RV-6. It took me 5 years but if I'd known how much fun it was going to be, I would have worked harder on it. Tips-odds & ends I used Van's squeezer for the # 6 spar rivets on the first RV. (Tennis elbow, too much scotch briting) On the second set of spars, I used the Avery tool. This worked very well. Tip-with the factory head down in the #6 set, I placed the ram with the hole in it over the rivet. The hole is a perfect fit. I then tapped the ram lightly to make sure that all of the flange strips were together. This also is a double check to make sure the factory head is setting in the #6 set properly. Then I inserted the flush set and wacked the ram 3 or 4 times with about a 3 lb. hammer. I used the money saved from not buying the Phlogiston spar to buy TOOLS!, a pnuematic rivet squeezer, a very worthwhile tool among others. When making my panel, I laid everything out on Masonite, the same shape as the alum. panel. I then drilled small holes at the center of each gauge or instrument and at the four corners of the radio stack cut-out. I then laid the Masonite over the aluminum panel and marked all of the centers, etc. so if the Masonite panel turned out OK, I wouldn't have to lay out everything again. I then cut all holes and cutouts in the Masonite and mounted all of the inst. and gauges in the Masonite and installed it in the airplane to make sure everything would fit. It worked so it was a simple matter to center punch the marks on the alum. panel and make the cut-outs. Fab air box. I clecoed the FAB bottom to the carb attach plate, installed the top & bottom cowl and then went in through the bottom cowl outlet with a block of wood and some body putty and bonded the FAB box to the cowl bottom. Then took top cowl off, un-clecoed the FAB bottom from the carb attach plate and removed bottom cowl with the now bonded in FAB box. It was then easier to fabricate the inlet to box layups. Also, on my FAB airbox, I put one strip of the baffle material along the top of the fwd part of the box (above the carb heat door). The other strip of cowl seal I bonded to the cowl inlet so it comes off with the bottom cowl. In other words, the FAB box nest in the rubber attached to the inlet. I also made removable front baffls that attach to the fwd horizontal baffels and fit under the lip on the bottom cowl. These two modifications made removal and installing the bottom cowl a lot easier. On the Tri gear, it should be realy easy as you don't have to clear the gear legs. Cowl hinge pins. On the two hinge pins that attach the top and bottom cowl, I scotch brited all of the cad plating off (therby reducing the dia. slightly.) I degreased the pins and put a light coat of "Moly Coat G" which is a molyibdimum disulfide (sp?) lubricant that I got years ago for the lubrication of firearms. It takes very little and doesn't gum up. It's very slick and kind of bonds into the metal. I then slid the pins into the hinges several times to transfer the moly to the hinge loops. The pins were easy to install and remove, no need to drill them in with a drill. As the hinge loops wear over the years, I can purchase new pins and keep the cad plating on to make up for a little of the wear. For pin security, I bent a hook in the end, screwed two drilled, fillister head screws to the front horizontal baffle and attached two, 1 1/4 inch long, fairly soft springs which I strech and hook over the bend in the hinge wire. To remove the pins, I detach the springs, slide a short piece of looped safety wire over the pin, stick the wire through the slot between cowl halves and pull on it with some small vice grips. I carry the wire loop and small vice grips in my a/c tool kit. My fingers are tired, so I'll quit for now. Hope some of the above ramblings were helpful to someone.

Subject: Van's WWW (Confusion Clarification)
RV-Listers: At the beginning of December, a small message was posted asking for any user contributed materials for the Van's WWW. The following days brought eight printed pages of concern into my mailbox. One of these was posted to the rv-list, so I feel it is necessary to answer in the public forum. > Isn't this going to make your site a duplication (or a repeat) of > John Hovan's Web Site? An understandable concern - but not the intention. I was primarily looking for some pictures of RV's that were already digitized - at the time, I didn't have the ability to scan any pictures. The intent was to add more pictures, as was requested by many. This was approved by Van's Aircraft. > If you are really going to represent Van's, the feedback should be > the other way. I personally would much prefer to see comments, articles, > PLANS/INSTRUCTIONS UPDATES, how-to articles, etc. come from the experts at > Vans factory .... after all, they do have more experience at building RVs > than most of us. Unfortunately, this sounds easier than it is. See the note about Van's and the Internet later on. > If it's not really a "Vans Aircraft" site (I find your e-mail > disclaimer a little strange) then does it really have any value-added over > John's Web site?? This is the offical Van's WWW site. I worked with Van's to put the web site together, and have only "Van's Approved" material. However, people have intrepreted this to mean that I work for Van's, which I don't (except at OSH). Therefore, my disclaimer, which said that any comments are my own and any tardiness on e-mail is not to be reflected upon Van's, was meant SOLELY for e-mail messages. I don't want to have someone quote a personal opinion that I might make on the list as an official statement from Van's Aircraft. > If it is somewhere in-between (a sort of semi-official > site) then the spectre of editorial control of negative comments is always > present in the background. Van's Aircraft has any control of negative comments, not me. > Perhaps you really need a clearly stated purpose for the site, and > an editorial policy statement? The site ended up targeting both builders and prospective builders, with more emphasis on those who have not yet purchased a kit. Most material was written by Van's Aircraft. Any that was not was approved. > ... just my personal comments ... Gil Alexander (ready for flames) > gil(at)rassp.hac.com General Comments and Notes: The original intent was to get Van's aircraft established on the Internet. After months of "pleading" for them to do something on their own, I realized that it would not happen, so I volunteered to create the site for them, free of charge of course. The problem is that not everybody holds a favoring opinion of the Internet at Van's. Things from the rv-list, in particular, have made their way to Van's. Negative posting are remembered much more than positive ones. Because of this, developing anything for them on the Internet is a challenge. Final Note: The Van's WWW site will be removed from earthlink.net on January 15, 1996. As always, any comments or flames are welcomed to jbenedic(at)uofport.edu Over 300 comments were received on the web site in the first few months, I was not able to reply to most of them. But yes - they were read.

I would like to get a electric die/disc grinder, however, the only ones I have seen in Harbor Freight, Sears, etc. have no way that I can see to adapt to a 1/4" Mandrel needed to use the Scotch Brite system.

I like it better than the Variprime that I used on my first RV. I Scotch Brite lightly with the grey SB and then clean with acetone or some other paint prep. I believe SW recommends 1.5 cat. to 1 part base. Is there a possibility that your batch of lacquer thinner became contaminated? I generally pour a small amount into a seperate container and even then am very careful to pour the liquid on the towel. It doesn't take much oil or silicon to ruin a whole can if you put the cloth or paper towel on the mouth of the can and tip the can to get liquid on the cloth. Was the temp warm enough? Do you have oil contamination in your air supply line? Did you let the paint cure long enough? Did you mix the two ingredients well?

Are you using the G4P (whatever the reducer is??) I bought this cheapo parts spray gun and Fred Meyers and tried doing my parts. Couldn't believe how much trouble I was having. (same exact thing happened to me, flaking paint) I tried everything I could think of, no success so..... I started using the little spray cans of Zinc Oxide primer and found it to leave a much darker coat and thought I was getting better adhesion. (Wrong!) I saw a guy a few hangars down using a DevillBiss (spelling) and I was amazed at how fast he could prime his parts. I bought one and tried the Sherman Williams again, the stuff went on like glue. I have bumped the painted parts pretty good with another piece of metal and most of the time it doesn't make it to bare metal. Not sure if the gun made that much of a difference, because I was painting under same atmospheric condition (humidity, temp etc) Don't know if you have a really good gun, but if not, I'd try borrowing someones and see if you get the same results.

Subject: Vans WWW opinion
When it is said the pages are going down on Jan15th!!!????? Why?? I hope it isn't going away for good. I am really curious what Van and other have against the Web? I think it is really great to have that type of resource. I'm sure there are a lot of question people call about that could be answered through the web. Having pictures of people's projects are also really inspiring. Something I wish could be added I saw on another users group list. Their web page has a link to the email that has been exchanged by subject, so the rv web page would have links something like: Email tips: Air tool oilers... Flying rv with skiis How do HVLP systems work? Problems with pitot tube etc.. etc.. You click on the topic you want and you are shown that thread of messages relating to the selected topic. It was a really neat idea and would be great for new users who come on the list, they don't have to re-ask questions already asked in the past. The problem is that this idea would require someone who understand how to accomplish this in an automated way. Which also means Van would have to hire someone. (wonder why he doesn't, there is so much that could be put on a web site) Whenever they make a change in the plans, the update can be posted in a graphic. Any manditory changes can be posted. Events etc.. etcc I really wonder Van's isn't interested in sponsoring a web page. Couldn't someone convice him that adding the web pages is part of the Total Performance package. hehe...... really. -Steve Day sday(at)pharmcomp.com (CK ID - RV6a RV for short) ________________________________________________________________________________

The fee is $10, and the reservation is for one year, at which time you have to renew (and send in another $10).

Well, unfortunately, you are PAST the point where you have the best chance, in my opinion. You want to start fitting the elevator to the HS before you have the tip rib installed, but after the root rib and weldment are riveted to the elevator spar. (This assuming that you have left the HS skin untrimmed at the tip) With the tip rib aff, it's very easy to get the rod-ends positioned correctly on the elevator spar. ONce that's done, then you can go ahead and install the tip rib. If I remember correctly, the next steps are: - rivet the skin on - roll the elevator skin leading edge - install the rod-ends in the elevator spar - add the lead counterweight to the tip rib (Did you know that Van sells pre-formed lead counterweights now?) - INstall the elevator tip - Trim the HS skin - Install the HS tip BTW, Frank Justice's instructions are extremely helpful in this area.

I tried some zinc oxide in spray cans from Aircraft Spruce and couldn't get one of the damned things to empty. Then I tried Mar Hyde in spray cans and they worked great. The problem is that Mar Hyde is not believed to be as good protection as Vari-Prime or even zinc oxide. I primed my horizontal and vertical stabs with Mar Hyde. A few days ago, I bought a De Vilbiss spray gun because I wanted to go back to Vari-Prime, which I had used much earlier and liked very much but gave up on because I didn't have a decent mask. Later, Gil Alexander and I bought a pair of positive pressure masks that work very well. I haven't tried the new gun yet but will do so this coming weekend when I prime my rudder components.

Subject: RV4's -Leaky Canopy ??
I've been working on fitting the side skins on my RV4 canopy. Since the side skins overlap the canopy near the canopy bottom, it obvious that water flowing down the canopy will find it way into the cockpit area. Van's doesn't mention the use of RTV or any other agent to seal this joint. Have any of you out there had a notion to seal this joint and if so with what? It seems to me that a good rain storm could leave a lot water inside the plane. Separate question. Has any body used the prefabbed NACA scoops (found in Aircraft Spruce or Wicks) on the curved area of the canopy skins. They are $20+ a throw and I just a soon not go throught the hasel of returning them if they won't work. Are the conopy sides an effective area for the NACA scoops or should I place them lower on the fuselage? -- Rich ________________________________________________________________________________

Subject: A couple of wing questions
I finished my landing light installation and attached the leading edge to the spar over the weekend. Feels pretty good to see the wing taking shape with riveted on parts. I am now ready to rivet on my single piece top skin but have a few questions for those who are working on their wings or recently finished them. 1) When did you countersink the inner row of screws on the fuel tank -- before Pro-Sealing and riveting or after the tank was completely assembled? 2) Has anyone installed the nut plates for this same row of screws with the bolts that hold the ribs in place already installed? If so, did the bolt heads get in the way of using a squeezer for riveting the nut plates? 3) I've looked high and low for a torque wrench in the 0-50 inch pound range to torgue the AN3 and AN4 bolts. The only one I have found was >$100! Did you actually use a torque wrench on these bolts or just tighten them nice and snug and called it good? Thanks for the help!

It has worked fine. I did find that its difficult to seal the fit between the forward top skin (F421) and the front skin on the bow. It showed up the first time I flew in rain. I ended up custom fabricating a one piece seal from one side to the other. It has to be thin enough not to bow up the front skin of the canopy when you close it, but thick enough to fill any void. I shaved down some "P" strip with a razorblade and put it on the lip of the forward top skin (F-421), it does the trick. No rainwater and a tight airseal. As far as the NACA ducts, It's been found that they don't work well on the skirts. They need a high pressure area and the skirts don't have it. If you want air off of the skirts the only ones I've seen that work are "pop outs" like you see on a Pitts. UGLY, but functional. I took my fresh air off the baffle and routed it to a console in front of the pilots stick. Works fine and the backseater gets enough flowthru air to keep them happy.

I'd like to broaden the topic being discussed by Randall and Elon a little: FAR 91.319 says: (c) Unless otherwise authorized by the Administrator in special operating limitations, no person may operate an aircraft that has an experimental certificate over a densely populated area or in a congested airway. The Administrator may issue special operating limitations for particular aircraft to permit takeoffs and landings to be conducted over a densely populated area or in a congested airway, in accordance with terms and conditions specified in the authorization in the interest of safety in air commerce. I'm somewhat confused about how this really limits us. How does one typically get/apply for these "special operating limitations" to fly near urban areas or in "congested" airways (which must include every victor airway in the Boston-Washington Corridor)? It seems to me that the absence of such a permit would pretty much preclude *any* IFR operations. > 91.319 EXPERIMENTAL Certificates: Operating Limitations... > C.

When you work with bare steel you really appreciate how fast it rust if its not painted and sealed correctly. I used Dupont Variprime quite a bit, however the problem I experienced with it was that it is not a sealer and needs to be top coated to keep out the moisture. I switched to the DP-Epoxy Primers because they are one of the best sealers made and do not need top coating. When I build an RV the PPG system I would use on my RV would be the following: 1. Start with the DX-533 Aluminum Cleaner 2. Then the DX-503 Aluminum Conditioner (visible or clear, I recommend the visible), this is the acid based coating chemical that will produce a chrome conversion coating on aluminum and its alloys. 3. Then use one of the DP Epoxy Primers, DP-40 = green, DP-48 = white, or use the DP-70 which is yellow and meets MLS(HML-P-23377). 4. On top of this I will use a base coat (color) clear coat system for the top coat. I really like the PPG DU-1000 Polyurethane Clear. It could be argued that the DP-70 is slightly better than the others but any of the DP-Epoxy Primers will give you a sealed primer surface which you will not get from the DX-1791 or from Dupont Variprime. If you use the DX-1791 or Variprime they need to be top coated to be sealed (to keep out moisture). Ive never heard of faying, could you describe what the condition is. I would also second Bob Skinners advice to you that you contact PPG tech assistance. If you explain to them what you are going to use their products on they will send you their spec sheets. The thing to keep in mind is that there are allot of good paint systems out there, just pick one and stick with it. If you try to use one companies primer and anthers top coat you are asking for problems. Curtis, ________________________________________________________________________________

NASA scoops I bought from VANS works great. Other builder/completers placed theirs a little different from mine and are not as effective.

RV6A vents I have even work in hot TEXAS, on the ground, whereas some RV6 won't even work very well in the air.

Regarding limits to flying experimentals over densely populated areas or congested airwys: there is a little known FAR that specifically addresses enforcement and investigation of this regulation: FAR 91.34 Enforcement and Investigation: Experimental Operating Limitation Violations (a) Investigation and enforcement against pilots who violate section 91.319 (c) shall be deemed suspended or low priority until such time as any operator of an experimental aircraft is invoved in an incident or accident involving people or persons on the ground who are in a schoolhouse, shopping mall, open air assembly, or a family or friend of a member of congress. After such time, enforcement of 91.319 (c) along with any other regulation relating either directly or indirectly to experimental-amateur built aircraft, shall be arbitrary and capricious, and new regulations highly restrictive to experimental aircraft shall immediately be put in place, and will be enforced retroactively. But seriously folks.... I believe that it's standard operating procedure for the inspector to write the "special operating limitations" allowing you to take off and land over densely populated areas or in congetsted airspace when they sign off your project, at least for proven designs like the RV series. But you may need to ask for it. I'm sure people who have been through the process can answer this better than me though. And in fact I wouldn't mind hearing from experienced folk about just what other sorts of signoffs you can ask for and/or expect. The ones I know about are IFR/VFR, Day/Night. What else?

Dick, I am just finishing my left elevator, so I have some recency of experience. Before going any further mount the skeleton to the HS and make sure the tip ribs fit with at least 1/8" clearance. You will have to use a square to make sure the tip ribs are being held perpendicular to the spar. Once this is done, drill and cleco the counterweight skin to the tip ribs, except where it goes under the elevator skin. Then mount the skeleton and skin in the jig and drill the skin to the skeleton, including where the skin overlaps the counterweight skin. Make sure the tip ribs are square to the spar. At this point you can follow Van's procedure or the Frank Justice procedure. The Justice procedure calls for you to rivet the CW skin to the elevator skin ( using 3/32 rivets) at the four rivet locations where there is no underlying rib or spar. (using this procedure requires 3/32' holes at these locations rather than 1/8" holes). Then mount the skeleton in the skin and the skin in the jig. Van's procedure is to rivit the CW skin to the tip ribs, the mount the skeleton in the skin and the skin in the jig. This procedure uses pop rivets in the above four rivet locations. I made the mistake of drilling the CW skins to the tip ribs with the tip ribs only clecoed together. After riveting the ribs together, the holes in the tip ribs did not match the skins; riveting pulled the ribs closer together. I hope this helped.

You should probably at least go out and find someone who has a torque wrench and torque a couple of bolts to get the feel of the required torque. You should then be able to go back and tighten them up close enough by feel. I don't remember the exact torque values, but remember you need to add the resistance for the locking nut-plate or fiber lock nut to the normal torque value for the bolts.

It is important to remember that what you can get away with varies from FSDO region to FSDO region (and from inspector to inspector). Obviously, there are a lot of high-performance homebuilts around that are certified for IFR. The best thing to do is to join one or more EAA local chapters in your area. Find some folks who have IFR-certified homebuilts. Ask them who the inspector/DAR was, and talk to the guy to see what he requires.

One reason is that RVers are great rumor-mongers, and Van likes to play things close to his chest and not release info on new projects, etc. until he's ready. With the internet it's really easy to spread rumors to LOTS of people. A number of times info has leaked out before Van wants to make it public, and through the internet a whole lot more people have heard stuff a lot faster than they would otherwise. Examples are the pre-announcement rumors about the RV-8, wild speculation on various accidents and investigations, and the posting of the Malaysian article (not the poster's fault but Van was upset about the article before it was posted on the internet). What Van's (and we!) need to understand is that the INTERNET doesn't spread rumors, PEOPLE spread rumors! Since I live close to Van's I spend a lot of time snooping around there and have personally tried to honor their wishes and not blab stuff until after they've announced it officially. I suggest we all use discretion in this area and maybe this will result in Van being more receptive to the advantages of the internet. > Something I wish could be added I saw on another users group list.

I use Tempo Zinc Chromate primer in cans for what I consider "non-critical" applications. i.e. places where two pieces of alclad metal touch, into bolt holes, etc. It provides very good corrosion protection, but marginal abrasion protection. Anything that might get scuffed; or for critical stuff (steel, spars, etc) I feel a lot more comfortable with SW.

Subject: Corrosion proofing steel
I have a question about sealing/primering steel against corrosion. I've been using PPG Metal Cleaner, then Metal Conditioner (I don't remember the numbers), before priming my steel parts. I've found that using this treatment, unless I dry the parts QUICKLY after rinsing, I will get some areas of light rust right away. Also, even though the label on the metal cleaner says it's supposed to lift out rust, it doesn't seem to do that very well and I have to scotch-brite any rust off completely off before using it. My questions are: is a little surface rust OK to prime over? Is there any other method that will stabilize rust better before priming? Also, what about inside the tubes where you can't get at it with scotch- brite? How paranoid about getting every speck of rust off the steel before priming do I have to be? After trying this method with several steel parts I'm starting to think it's better to just sandblast the parts and wipe down with lacquer thinner, and priming directly over that instead of trying to use some fancy metal conditioning treatment that seems to result in MORE rust. I might mention here that I'm not really interested in doing any fancy powder-coating or chroming of the rudder pedals, control sticks, engine mount, etc. I just want to prime and paint with good quality primer and paint.

Subject: IFR requirments...
Speaking (again) of IFR requirments, I should have been more specific when I said "all electric". I envision two electrical systems each driving an electronic ignition unit. Two of those little geo metro alternators and two of those little gel-cell batteries. I get to eliminate all of the mag maintenance and the plumbing/ hassle, not to mention the potential danger, of the vacuum pump. I know that an Electric horizon is expensive, but in my fantasy panel, I would have only the minimum instrumentation for "safe" flight. A "perfect" panel would be: a horizon, a gps, and a comm radio, nothing else. Low maintenance low cost, and low hassle. Practically speaking, you need more than that but every piece beyond the basics will have to "earn" it's way into the panel. Aside from the legalities, I don't know of a good way to back up the electric horizon?? To pony up the $$ for one of them might hurt, I don't think I could swing two of them. If the FAA makes me put too much "junk" in the panel for IFR, I am thinking that I may just make the plane VFR only. I don't want to replicate the sorry state of GA panels in certified airplanes. I want something lean and mean and simple to maintain. I've got a few years to go, so there's no rush. Any thought would be appreciated.

I countersunk after assembly and curing. Initially I drilled the holes to 1/8" so that I could use clecoes to help hold the tank together while the pro-seal was curing, then drilled out to the final size and countersunk afterwards. The proseal layer adds to the overall thickness of the material, so I don't think pre-countersinking would be a good idea. > 2) Has anyone installed the nut plates for this same row > of screws with the bolts that hold the ribs in place > already installed?

Its a good idea to have the bolts in place when you are installing the nutplates, so that you *can* work around them when necessary.

Did you actually > use a torque wrench on these bolts or just tighten > them nice and snug and called it good? I found a 1/4" drive torque wrench for about $30. Its a cheap import, and not very accurate as far as I can tell (+/- 5 in=lbs), but its a whole lot more accurate than doing it by feel. Case in point: On my first wing I tightened my bolts til they "felt right". When I got my mini-torque wrench I discovered, even considereing the error of the wrench, that I had over-tightened the bolts by more than 100%! 25-30 in-lbs is not very much torque at all. If I were tightening by feel, I would probably recommend using a *nutdriver* instead of a rachet wrench. 25 in-lbs with even a small rachet wrench feels like nothing. Considering the large number of AN bolts in the RV airframe, and their relative importance to the survival of the pilot, I don't think $100 for a good torque wrench is unreasonable. I wish I'd bought a good one. Cheers, Curt Reimer ________________________________________________________________________________

If you dont use the metal conditioner then you need to use a self etching primer. After you wash off the conditioner dry the surface as fast as you can, I use a blow gun and my compressor. This will still leave you with a small amount of surface rust, remove this rust with one of the following PPG cleaners, DX-330, DX-220 or DX-380. These cleaners are the same cleaners you would use before priming. If you are using Variprime Dupont recommends 3919s Prep-Sol or 3929s Prep-Sol II. The PPG DX-330 is very good at removing grease & silicone which can really mess up a paint job. For the tubes I would block off one end and pour in some of the Metal Cleaner, and shake it for awhile, then do the same with the Metal Conditioner, then drain it and blow it dry. Then paint the inside of the tube with an epoxy primer, if you have a compressor and spray gun just place the tube against the spray gun and spray, you dont need to worry about runs in the tubes. I hope this will be of some help. Curtis ________________________________________________________________________________

While on the subject of elevators, be VEWY VEWY careful about the alignment between counterbalance and elevator horn. One of the most common problems I have seen is that when it comes to lining up both elevators on the HS, you can line up the horns or the tips but not both. This is usually because of warpage in the LEFT elevator , the most flimsy(I think). What seems to happen is that using the same fixture for both elevators multiplies any errors.

That and the altimiter (required) constitutes "partial panel" for pitch and roll that can be used to get you out of a pinch if the Horizon goes out. Of course you would want to put the Horizon and Turn and bank indicators on different circuits. > If the FAA makes me put too much "junk" in the panel for IFR, I am thinking > that I may just make the plane VFR only.

Well to clear it up, here's the FAR that deals with how much "junk" you'll really need. Note that (1) and (2) specify day and night VFR stuff that you have to have as well. Sec. 91.205 (d) Instrument flight rules. For IFR flight, the following instruments and equipment are required: (1) Instruments and equipment specified in paragraph (b) of this section, and, for night flight, instruments and equipment specified in paragraph (c) of this section. (2) Two-way radio communications system and navigational equipment appropriate to the ground facilities to be used. (3) Gyroscopic rate-of-turn indicator, except on the following aircraft: [... snip cause it's N/A ...] (4) Slip-skid indicator. (5) Sensitive altimeter adjustable for barometric pressure. (6) A clock displaying hours, minutes, and seconds with a sweep-second pointer or digital presentation. (7) Generator or alternator of adequate capacity.

The book will be available about 1 1/2 months after we all receive the December 1995 RV-Ator from Ken at Vans. But first, I'm writing to ask your help. I need three things. 1] BUILDERS CLUBS I need to update the list of builder's clubs. If you are a member of, or know of a builder's club please e-mail me the club's name, the name of the leader, and his or her address and phone number.

(the 14 year cover featured two RV-4s in inverted formation near Seattle) Flying photos are great, but building pictures could work too, as long as it's interesting and unusual. I'll pick a photo based on content, clarity and lighting. If I pick yours, you'll get a free book. If the picture has more than one plane, then everyone pictured will get a book, including the photographer in the event of an air-air shot. (up to five please) Please tell me if you want the picture returned. 3] OTHER SUGGESTIONS For those who have the 14 year book, if you'd like to make a suggestion for the new edition, now is the time.

Subject: Re: RV4's -Leaky Canopy ??
When I was at Copperstate in 1993 I asked every RV-4 owner on the field I could find what they thought on the canopy skirt mounted vents. Everyone I spoke with who had such vents were disappointed in the amount of airflow. Most also described the problem as notably worse for the rear seat occupant. Tony Bingelis addressed this problem and proposed a "better" solution in his column in the March 1991 Sport Aviation. This solution was a front baffle mounted air pickup, with SCAT tubing to the cockpit. Bingelis claims the airflow obtained was the best he had experienced. When I had my factory demo ride with Bill Benedict, I discussed this method with him. He thought it was a good one, but also pointed out a potential for an engine fire following the duct work into the cockpit. A solution to the fire integrity question may be a firewall-mounted cabin heat-like butterfly valve to allow you to shut off the airflow at the firewall. I have also considered a plenum chamber to reduce duct/airflow noise, but I may just hold off this extra bit of work until I see how bad a problem this may or may not be. Cooling the rear seat is the bigger problem, one I also saw well addressed by an RV-4 at Copperstate. It had a NACA duct on the bottom of the left wing, just behind the main spar and just outside the wingwalk area. This had ducting running to an outlet in the rear control stick well. The owner has high praise for this installation, this method was also highly recommended in the RV-6 message thread on the AOL homebuilt forum. This is any easy mod that I have already installed using a NACA duct from Van's. Hope this was helpful.

Rich Sealing them with a bead of sealer is what I did. I used a black gooy substance I can't remember the name of, which I obtained from a winshield installer. The material was one that was paintable. I masked the metal at the line where it meets the canopy and about a 1/8 to 1/4 inch above that on the plexiglass I put another line of electrical tape. I then spread the material with a popsical (sp) stick and once it had dried removed the lower tape from the metal sides and left the electrical tape on the canopy and used this to mask prior to painting. After, painting the seal looks good, the paint hides it completly. It has not been in weather yet but I see no reason for it to leak. >Separate question.

Subject: Re: 16 years of the RV-ator
Hi Andy, I haven't announced it yet to the RV-List but in a couple of weeks Matronics will have a new web page on the Internet. Along with detailed promos for the Matronics FuelScan and Governor products is a complete section on the RV-List including a subscrition form, and browsable RV-List Archives. It seems like these might be good things to include in the publication somewhere. As I said, the pages aren't quite complete and I havn't yet announced it on the List but I suspect to have the whole thing ready in about 2 weeks. Here is a breakdown of the Web URLs that will be available: http://www.matronics.com/index.html Matronics Homepage. Links to all other pages from here. http://www.matronics.com/rv-list/index.html RV-List Homepage http://www.matronics.com/fuelscan/index.html FuelScan Promo http://www.matronics.com/governor/index.html Governor Mk III Promo For now I would prefer that these pages not be general knowledge until they are complete. I will announce their availability on the RV-List as soon as they're ready. Thanks! Matt Dralle RV-List Admin. >-------------- >Yes, the 16 year RV-ator book and update pages are now being prepared.

It was big enough that even the engine mount fit. I handled all steel pieces with latex gloves after the bead blast, wiped down with paint prep and sprayed away. On some steel parts, I used a Dupont metal stabalizer that seemed similar to blueing a gun. Didn't notice any rusting. Where do you live? I'm in Nebr. and it does get humid in the summer. I put a de-humidifier (and airconditioner) in the shop. Really dropped the humidity. Bob Skinner ________________________________________________________________________________

They are used extensively in some types of pipe welding. I have an old Black & Decker model 4286 but I think it spins too fast and has too little torque for good cutting. Be very carefull in matching the RPMs of the grinder to the type of wheels you buy for it. They can be deadly when they explode. ________________________________________________________________________________

Hi! I've just spent the evening trying to read through the archive. Only got to May '91, but can't wait to ask this: 1) Is the $575 tool kit from US Tools&Supply the best deal or would it be smarter to buy individual pieces? I don't think I need the air drill, and can get a used rivet gun for $105 (US Industial Tool, pg 163 Trade-a-plane Jan '96). 2) I'm considering buying a half-built (or so) RV-3. WIngs are complerte, fuselage in boat stage. The question here is how do I document the parts already built - and will I still be under the 51% rule -- guy selling it (brought it from someone else as is now) says no problem. But reading the earlier postings here leaves me wondering. Any input on these points would be greatly appreciated!
