      Check the vent hole.  If it is plugged,  that was what caused most of my
      problems.  You can thin veriprime with acetone.  thinned out primer sprays a
      lot easier.  you are looking for a very thin coat anyway.

Yes, I initially flew my RV-6A without the wood stiffeners and disliked the amount of bouncing and swaying. I tried the nose gear as well without the stiffeners and found that it did shimmy under certain conditions. I then applied the stiffeners and liked the ride much better.

I check my original nose gear with dye penetration and found no cracks, but changed over to the beefer nose gear that van offer as replacement just to be on safe side. I flew the new one initially without the stiffener and noticed what appeared to be a tendency for the nose gear to tuck under (at least that is what it felt like - I am certain it was not really tucking under), so added the stiffener and that went away. No need to add wood if your gear is giving you what you want. I would not suggest that anyone take my advice over Van's regarding wood stiffeners, it is just that I have tried it both ways and found I prefer the gear with wood stiffeners. > 2.

Whether the gear would have hopped without the wood stiffeners is conjecture on my part, but having seem similar response to hard braking with wheels on spring gears, I do believe that the stiffeners minimized that tendency. But hopefully, most folks will not face that situtation to find out. > Didn't I just read in one of the threads that Van's no longer suggests > the wood stiffeners?

In the 70's there was an article in an aviation magazine about an STC for a Piper that allowed full flight envelope power control with wide-open throttle and power moderation with mixture. In an emergency you will disregard the roughness when well lean of peak. The engine is getting its cooling from excess air rather than fuel.

Thanks for the clarification, Cy. The ensuing backfire could also start a fire. As a matter of safety, I'd feel more comfortable if list members would leave suggestions on emergency procedures to those that are qualified to answer them. I respect the right of any member to comment on any topic but I feel this is a critical area with respect to safety. Some of the comments (Lyc's can't run continuously at 100% power, use mag switch to moderate power) could get a pilot into trouble. Please don't take offense gentlemen -- valuable RVs and even more valuable lives are potentially at stake here. Off my soapbox -- and my apologies for the rather direct wording.

The only reason I can think of not to rivet them on until needed is that unless the holes and location of the bracket are predrilled (by the factory) then you really have no idea where the final location of the bracket should be. It may ve close enough, or then again it might not. My rule of thumb when building my non prepunched 6A was to not drill or rivet anything until I absolutly had to.

The C-85 in my old Aeronca Champ would start just fine at full throttle. A little used hot-start procedure only used when there was a qualified hand-propper on the front and a qualified pilot in the seat. Many a pilot have found out that without the aforementioned precautions, a plane will start up, leap forward, and chew up other airplanes or even take to the air, not caring that there wasn't a qualified pilot at the controls or any pilot for that matter. -- Scott VanArtsdalen, MCSE, CCNA Network Adminstrator Union Safe Deposit Bank 209-946-5116 "Fear of failure is only for the weak and arrogant, for those who foolishly think that somehow they can achieve success without paying the price." -----Original Message----- From: Mike Thompson [mailto:grobdriver(at)yahoo.com] Sent: Wednesday, February 14, 2001 7:10 AM Subject: Re: RV-List: Faster than normal landing, (was Component structural failure...) > I'm not convinced that a Lyc would restart with the throttle wide > open. > Anyone tried that?

l failure...) I find this thread disturbing. If you build the a/c to proper specs and then maintain the a/c in a reasonably timely manner i.e. performing 25, 50, 75, and 100 hour inspections also the annual you should not have a problem with sticking or broken throttle cables or for that matter mixture cables cracked weldments etc. We are building an airplane to fly in and I believe that safety is paramount. The aformentioned problem was on a spam can and probably in all likelyhood maintained by a mechanic that was not paid well because he obviously did not pay attention to detail. Guys just build the airplane to spec's and maintain those specs and since most all of us that are building will have the repairmans certificate on that airplane, maintain that airplane as if your life depended on it because someday it just might. To the other guys who do not have the repairmans certificate I would suggest getting an A&P who is familiar with the RV series a/c. Do not use anyone who is not for this reason. An A&P who is "type specific" will know the intricacies of the a/c and know what to look for while performing your annual. Sure you may get an A&P who is thourough but in the back of your mind do you want a job done by a guy who is not really familiar with your a/c? that is for you to decide. I just hate to see needless accidents due to negligence or pure stupidity.

But like other comments on this thread, it's off the subject. Bob is retired from TRW. After spending his carrer designing antenna's for TRW. Bob has documented REAL radiation patterns of antenna's on also any shape imaginable. If Bob says that the best location for a COM antenna is on top of the vertical stabilizer, it's because he has PLOTTED that radiation pattern, and the radiation pattern for every other imaginable location of an antenna on an aircraft. (Bob may have started with a textbook, but it went past it long ago.) If Bob Archer's wingtip COM antenna works as well as a standard belly mounted COM, why put the COM antenna on the belly? The question is mine; The choice is yours. Bob will still tell you that the best COM antenna location is on the top of vertical stabilizer.

The thoughtful exchange of ideas (even bad ones) help to stimulate thinking. Welcome to one of the major drawbacks of the information age......too much information.

And the people doing the inspections are probably better at it than I am. Many of the responders to this thread were discussing the prudent practice of spring loading the throttle to the open position IN THE EVENT of a break. In addition, several posters on the List have had these cables break. Your assumption that they broke because they failed to perform an adequate inspection is flawed at best. >We are building an airplane to fly in and I believe that >safety is paramount.

Building and maintaining to specs will not prevent mechanical failures from occurring. That's why we have redundant systems, checklists, etc. And that's why we practice emergency procedures and maneuvers. You are entitled to your opinions Glenn, as we all are. But I think this thread has wandered just a little off course. I consider it prudent to back up your throttle and mixture connections with a 5 cent spring so that in the unlikely event of a failure, you have an opportunity to prevent a small failure (cable broke) from turning into a larger failure (off airport landing). The subsequent questions on how one controls speed with a broken throttle cable is a good one, in my opinion.

Subject: IO-360 Throttle and mixture Bracket
Bob, This is not RV-specific, but one approach. I owned a Citabria with an IO-320 and Bendix injector. The throttle cable (swivel-end style) was attached to a bracket, with about a 6 inch arm, welded to the lower left engine mount tube. There was probably 10-12 inches from the bracket to the servo arm. The mixture was just a bowden cable attached to the lower right mount tube and an adel clamp on the airbox. See if you can find a Super Decathalon and see their mounting for an IO-360.

Personally, I've learned from this thread not to emulate techniques used on rotary-engined aircraft nearly 100 years ago, as I probably would have tried to do if my rented aircraft went to and stuck at full throttle a week ago. Neither my basic instructor, or numerous BFR check rides since, ever covered that eventuality. I bristled a little today at comments made implying that if I'm not a Super-CFI or career piston pilot I shouldn't be adding my two-cents worth, lest someone else use them to their detriment - but many of these threads usually start with a question or ignorant comment and through the combined experience of the participants the truth and best-practices generally shine through at the end.

I beg to differ with your statement that Lycs can "only run a few minutes at full power". When I'm practicing my far off in the future Vegas pylon turns, running my "low altitude fast route or just smoking along, I can run max 2800 rpm for quite a long period of time without any signs of excessive EGT/CHT/oil temp or pressure, etc. In fact, I think I can hear my engine singing along with me on the ride, tho it is in better tune.

Subject: Re: Aileron mounting brackets
I mounted mine whilst the wing was in the jig. I installed the brackets first, after the top wing skins, this way I could have the ailerons hanging whilst testing out the pushrod assembly and making bits and pieces. Don't forget, Van's also tells you that you can rivet the bottom skins on after it is out of the jig, just to be carefull moving the wing out off the jig. I thought riveting the bottom skins on in the jig would make more sence with the wings in the jig, unmoved. This meant riveting the brackets on inthe jig too I believe Ole George did it in the jig on the video too. I defenitely would do it again, all in the jig. Gert 80721 p.s. in the end it's a horse a piece, If you have a good table to put the wing on it doesn't make that much difference. You can always ask me more off of the list.

Listers, As Gert mentioned, the conversion isn't hard. Been there, done that. Essentially, you need to drill out 14 3/16" rivets in the F-804A. These holes get opened up to 1/4" for the bolts which will hold the landing gear weldments on. I ordered an 8A wing kit but received an 8 center section. I spent 2 hours carefully marking and drilling out the necessary rivets. My weldments fit perfectly. Be aware that your rudder cable holes will need to be relocated for the 8A.

Gert: Your answer to the aileron bracket was an excellent procedure. I have been down this avenue with two Rv's. The thing that is difficult is the vertical positioning is critical to make the airfoil conform to the wing. As you will notice from previous builders aileron and flap alignment is easy to do in the jig. Also you notice the quickbuilt has all the wing assembled but the outboard top skin. The Ortmdorf method works, I have had to replace brackets that were not aligned properly, not fun. I think all Rv-6 builders will tell you to be extra careful in the alignment as it will bite you later when you install flaps and wing tips for a perfect alignment of the wing.

Dear fellow RV-List'ers: I had been trying to locate a supplier for some small latches made by Hartwell. They are plastic, you push on a plunger, that expands a grommet, and that holds your panel closed. They are small, lightweight, and have great holding power. The only problem was I couldn't find them anywhere. I contacted Aircraft Spruce and good as their customer service is, they really didn't want to bother with such a small order. I then contacted Wicks and asked for help. Deeann Vogel of Wicks has worked for two months trying to find a suitable supplier. She took great pains to make sure I had the correct part numbers and was going to get exactly the latches I wanted. You don't find that kind of customer support too often. When I do see examples of stellar customer support I like to spread the word. From now on, I'm going to try to do as much of my purchasing as I can from Wicks. -- Scott VanArtsdalen, MCSE, CCNA Network Adminstrator Union Safe Deposit Bank 209-946-5116 "Fear of failure is only for the weak and arrogant, for those who foolishly think that somehow they can achieve success without paying the price." ________________________________________________________________________________

Ok, I've had enough. We all know adding the spring won't hurt. My thought, just do it.

Bruce, In my RV-8A with an IO-360 I have the flow meter mounted almost exactly 4 inches downstream from the servo with a 90 degree elbow coming out of it then the line going directly up to the flow divider. It is not the optimum 5 inches that they suggest but it works prefectly. After 25 hours of flying every fillup has been within 1/10 of a gallon of what the VM1000 says has been burned. I made a small strap of aluminum bolted to the mounting hole in the flowmeter and the other end to the engine case oil sump bolts to give a little support to the small rigid 4 inch line between the flowmeter and the servo.

Only problem is that there are no injection-molded models of the RV series available. I've checked the catalogs and talked to the model shop owners.

Thank you for your inquiry. Our Cool Jugs conversion kit is just that - a kit that converts virtually any wide or narrow deck O-360 or O-540 series Lycoming engine to liquid cooling. This includes carbureted, fuel injected, turbocharged and turbo-normalized engines. Running liquid cooled the cylinder head temps are maintained at a steady 190 deg F (+/- 5 deg F). Cylinder to cylinder temp variance is essentially eliminated as all cylinder temps run within 2 deg F of each other. Shock cooling and heating are *completely* eliminated. Cool Jugs is a complete, bolt-on kit that will allow a conventional air cooled O-360 or O-540 parallel valve Lycoming engine to be converted to liquid cooling. The result is a fully liquid cooled aircraft piston engine. An engine that operates at a stable 190 degF without any* need for airflow over or through the engine compartment. The Cool Jugs liquid cooled conversion requires absolutely no internal engine modifications! In fact no existing reciprocating/moving components are changed in any manner. The conversion creates only one additional moving part - the coolant pump, which is grear driven via a standard accessory pad. Normally aspirated engines can be run at peak lean EGT or even at 50 deg F lean of peak EGT at *all* power settings and RPMs providing you with substantial fuel savings and *more* power. You also have the option of using the higher compression 9.0:1 pistons for even greater power. The stock O-360 engines typically run 8.5:1 pistons. Our dyno testing shows that an O-360 with 9.0:1 pistons puts out 195HP at 28"Hg manifold pressure at peak EGT resulting in a fuel burn of 11.7gph without even a hint of detonation. Keep in mind this is at sea level pressure. The best an air-cooled O-360 can do is around 12.5gph at peak EGT, 28"Hg manifold pressure and that's with occasional detonation occuring. In fact as part of our dyno testing we ran a detonation survey on our liquid cooled O-360 in an attempt to discover if and under what conditions detonation might occur. What we found was that we could run the engine at wide open throttle (28"HG manifold pressure) at peak EGT and even at 50 degF lean of peak EGT and load the engine down to 1600 rpm (as much load as the dyno could apply) and left it there for as long as 20 minutes without so much as a hint of detonation. That's practically the equivalent of running wide open throttle with a feathered propeller. The reason you get more power when running at peak lean EGT is because you aren't cooling the combustion mixture with excess fuel so you get more thermal energy and in turn more power. You absolutely don't have to be concerned about 'burning up' our liquid cooled engine running at peak EGT or even 50 deg F lean of peak EGT - even at sea level manifold pressure. In fact running at peak EGT at all times will actually improve the life expectancy of the engine since it prevents the buildup of lead deposits. For reference a typical air-cooled O-360 running at wide open throttle (28"Hg) at full rich will consume over 18gph. Even at altitudes above 3000' when leaning is possible, an air-cooled O-360 will consume more fuel because it is (a) running much hotter, around 380-400 degF and (b) due to uneven cylinder temps, you can only lean until the hottest cylinder starts to misfire. You should consider that installing a liquid cooled engine in any airframe will require re-design of the cowling since our engine does not require any* airflow through the engine compartment. You should also consider where you might be able to locate the radiator. You will need approx. 5000 CFM of cooling air for the radiator. A well designed low drag radiator installation should incorporate a relatively small air intake and a ducted air plenum to the radiator that provides for at least a 3-4 times expansion of the air intake. *Note: A small volume of 'breather' air is recommended for cooling the alternator and generally keeping the engine compartment ventillated against any buildup of fumes. You may also need separate cooling air for the magnetos and possibly the fuel pump. The radiator for the O-360 engine is fairly small (14" h x6" w x6" d) and could be mounted in the engine compartment or remotely depending on the airframe. We can have a custom radiator built to meet your needs. A properly designed installation would be to have no more than a 24 sq" intake and a ducted plenum that gradually expands to meet the radiator face which is actually 12"x6" (72 sq"). The expansion rate should be limited to 15 deg in order to prevent undesirable turbulence from developing within the plenum. This may in some cases result in an expansion plenum that is too long for a given airframe installation to be practical. In such cases internal vanes can be incorporated in the plenum in order to spearate and maintain a 15 deg expansion path. For more information take a look at the following site: http://www.inforamp.net/~raac/CoolingSystems/CoolingSystemsIndex.HTML Weight ------ A typical conversion will add an additional 30-35 lbs to an engine installation. This weight includes all of the components, radiator, hoses and coolant. The coolant is the largest percentage of additional weight since water (glycol/water mix) weighs 8lbs/gal and the typical system requires 2 to 2.5 gallons of coolant. A significant portion (12 lbs) of this weight can be offset by installing a lightweight starter. Given the potential performance improvements both in terms of drag reduction and engine life expectancy we feel confident that the additional weight of a liquid cooled engine will be more than offset by its benefits. While we can't address the potential of additional weight savings in every airframe we can tell you that in converting a Piper PA28-180 to liquid cooling we expect to offset a significant portion of the additional weight with a *much* lighter cowling. The redesigned cowling will be built from carbon fiber and we anticipate that it will be approx. 10-12lbs lighter than the original cowling. This savings along with the removal of the aircooled baffling and changing the induction air box will result in an additional 7-8 lbs of weight savings. Overall, with the lightweight starter (12lbs), cowling (10lbs), air-cooled baffling (3lbs) and induction air box changes (5lbs) we have managed to achieve 30lbs of weight savings - virtually offsetting all of the weight gain of the liquid cooled O-360. Certification ------------- Currently the Cool Jugs liquid cooled conversion kits are not FAA certified and are for experimental use only. Liquid Cooled Air Power is persuing FAA certification and are hoping to achieve certification by late 2001. Pricing ------- Our Cool Jugs conversions are available for both the O-360 series and O-540 series engines. The Cool Jugs conversion kit includes: . New nitrided cylinders/valve train All valve train components are New FAA-PMA approved parts: o Intake and Exhaust valves o Valve seats o Valve Springs o Rocker Arm bushings o Top end gasket set o Rocker box covers . Coolant manifold & Coolant pump . Thermostat housing & thermostat . Engine hoses o Steel braided Aeroquip TSO C53a 1000psi test hose o AN fittings .

Subject: Re: Faster than normal landing, (was Component structura
Jim, I drilled a small hole in the large washer that is used as a retainer on the outside of the rod end bearing where it is bolted to the throttle arm. I then went down to my local Ace Hardware and bought a small selection of lightweight springs of various lengths. I then bent a small tab and mounted it underneath the forward right nut that holds the carburator to the intake stud. It took just a little experimentation to get a spring that would stretch easily through the full swing of the throttle arm without applying too much tension. I also played a little with different tab lengths and dimensions. Overall, it probably didn't take me more than a half hour or so. The spring on the mixture cable was a little more difficult because of the mixture arm's location and swing pattern. However, a little experimentation there and I was able to attach it to the washer (like the throttle) and to the mixture/throttle cable bracket. Cheap insurance and not hard to do.

Well, this the bare minimum to qualify as a jig. What you need is a way to support the wing's front spar and rib structure while you put the skins and other stuff on. Van's recommends 2 posts about 133" apart with a angle brace about shoulder height on each post to support the spar and keep it level. That's all you need but many builders have been more elaborate, sometimes building both wings at once and some even made the jig or frame on caster so they can roll it out of the way. Not the kind of jigs other RV models require!

Greg and others: >> I was under the understanding that with the 9, it wasn't absolutely necessary to have a jig. Can anybody confirm this? << That's right. You don't need a jig in the sense of a kit that is not predrilled. You just need something to hold up the wing while you work on it - doesn't have to be trued. At a couple of points (like mounting the tank) it has to close to true - about 1/4" is okay. The instructions tell you how and when to do it. The jig in the empenage documentation shows two uprights 133" apart. That is the jig they are talking about. Just install a couple of brackets to hold the spar. Pretty simple.

Date: Feb 16, 2001
Hi All, I'm helping a friend drill the fuselage aft side skins on an RV-6. Last week we drilled (backdrilled thru the bulkheads) the left side skin. We didn't notice at the time but the panel just behind the baggage bulkhead is loose, meaning you can push it in with your hand to oil-can it. On the right side we stopped drilling after the j-stringer next to the longeron was drilled 'cause it also had loose skin in the same place. He had his straps in between the bulkheads whereas when I built mine, i put the straps next to the bulkheads. Does the strap location make a difference or is this skin just formed this way? We didn't have time to shift the straps around tonight to find out so I thought I'd ask the List.

Subject: Wing rib rivet distance-pre punched 6
When drilling the inboard bottom wing skin, the last three or four rivets (aft) on a few ribs are very very close to the bend of the rib flange. Yeah I thought I could move these as I riveted toward them but it did not work out like I expected. These are the two-three ribs outboard of the walkway, but on the bottom. I may have to use a few cherry maxs due to the fact that I may have difficulty in bucking. Question: Do you guys think I should leave as is, or add another rivet or two between current rivet holes-in the proper rib placement of course? The row of aft skin holes that attach to the rear spar align nearly perfect. Structurally am I fine without adding extra rivets?

Subject: Throtle Spring
From: Gary Graham <beeb(at)teleport.com>
There I was at 10,000 feet. Once upon a time I was cruising along in my RV-4 when all of a sudden I was set upon by really rough air. Not wanting to crack the canopy with my noggin, I abruptly reduced my power setting. To my dismay I was holding the power control in my left hand. It must have failed somewhere between the black knob and the the carburetor. To my good fortune I had been a subscriber to the "RV List Digest" and only the week before had installed a "power on spring" to my throttle arm. However, because I sometimes think "outside the box", I had installed the spring (with a length of 1/16th inch stainless aircraft cable) so that the spring was fully collapsed with only partial power (16 inches MP). After I broke out of the rough air I joined up with a large flight of C-150's that were heading my way. They made me fly lead because I didn't have a formation endorsement (not to mention that I was speed control chalanged). We had a great time flying along for what seemed like hours. I wish I could have seen all the things that they were pointing out on the ground. I made an almost normal landing (one mag off on long final). I pulled my mixture in the round out. Darn if I didn't have to land with a Red knob in my left hand. Gary, On the ground in the N.W. ________________________________________________________________________________

Albert- I don't like to squat or sit on the floor so I opted to mount my spar at about eye level. The only time you'll spend at the top (front) of your wing is drilling the front of the tank and leading edge skin (oh, you're building a -9, don't have do do that!) and perhaps dealing with the tank to LE attach platenuts. If the -9 wing is similar to my -6A, you'll spend MUCH more time doing stuff like flap on/flap off, aileron on/off, fitting/attaching aileron brackets, fitting gap seal, flap brace etc. I have a small office chair on wheels that's low enough to roll back and forth under the spar and have done much work sitting. At this height, you can balance the trailing edge of the flap and aileron on your knees for attachment and removal. Has worked very well. Just be sure to pad the end of your spar- it'll put your eye out!!! ;) From the PossumWorks in TN Mark -ALMOST done with 2nd wing!!!

Fellow builders - I built my wings several years ago but found that when I had completed the wing , less the cotrol surfaces, that it was easier to flip the wing over so it sat leading edge down. I moved the jig arms down so that the wing leading edge was about 6" off the floor and that left the trailing edge at a good working height and was much easier installing the aileron hinges, flap brace, and control surfaces.

If you get the straps in between bulkheads you'll pull the skin in beyond the normal line, and then when drilled and the straps released that skin will be loose. You had it right - tighten the straps on top of the bulkheads to avoid this, and to avoid bending longerons.

I've noticed vans is now adding the bulkhead and changing to epoxy pants. But, could you elaborate on the balancing procedure you used on the wheel pants. I also wonder why balance would make that big of difference to a stationary (non-rotating) wheel pant?? Why wouldn't we spin balance the tire- rims?? As compared to its physical alignment with the airflow, balance would seem to be secondary. I'm very curious, as it's been posted as a remedy for some time...

First put a bulkhead behind the wheel (I don't see them on Van's products, but Sam James has a nice cut out that can be glassed in) to keep dirt out of the rear of the pants, then balance them, IMHO.

I've been starting to pick up some vibrations in my 6A. Its not that noticeable yet, but I can feel an increased overall roughness. I can also definitely feel it if I touch the panel, as do the instruments, as the altimeter needle is starting to bounce around. My mag checks are good and my 4 egts appear normal within less than 100 degrees of each other. I suspect that my 4 1/2 year old wood prop is starting to go out of balance, mostly because when we used to have these problems with ultralights, a good prop balance job or a new prop would typically make it go away. Then, when I switched to Composite props which stay in balance, the periodic vibration problems never returned. Any comments? Is re-balancing of wood props considered standard maintenance every 4-5 years? Andy ________________________________________________________________________________

The trouble is that the sides of the canopy next to the passenger don't appear to come all the way down to the tubing on the frame. Do I need to just pull the sides down and make them fit? I still need to trim the final millimeters of flange off of these sides which will shorten them even more.

Gene, it you can double nut the stud and turn it out, this might be the time. The old stud can be replaced with an over size stud. On the other hand if it is tight and holds the proper torque, forget it. Many studs come out when the nut corrodes so that they come out when you try loosening the nut. That all is the time to get an over-sized replacement stud. They come in about .003 increments so your can get .003, .006, .009 oversize and are listed in the Continental parts book.

What I think is happening is that by adding weight in the nose of the assembly, you greatly increase the moment of inertia of the wheel pant, which changes (slows) its natural vibration frequency. I'm guessing that the natural frequency of an unbalanced set of wheel pants can be close enough to that of the gear legs that when one starts vibrating, the other follows.

We have a small problem (I hope) with the fit of our spinner.

We've fitted the cowl and have a good 1/4" clearance the bulkhead. As we see it we have three options: (Would appreciate additional ones) 1. Cut out the center of the front bulkhead and rivet in a 1/8" spacer plate to shift the spinner 1/8" closer to the cowl. This will allow us to add a couple washers - giving clearence between the prop blades and and the rear bulkhead in flat pitch and retain 1/8' clearence between the rear bulkhead?rear of spinner and the cowl. 2. Cut out or relieve the small area on the rear bulk head that is in contact with the prop. Not sure sure how. This retains the 1/4" clearence between the rear bulkhead & and cowl. 3. Follow Van's advice and forget about the fact that our C/S prop contacts the rear bulkhead and flexes it. We are leaning toward option # 1, but would appreciate any commments/suggestions.

The aft bow then had to be reformed to fit the Plexiglas...not easy because it is 6061 T6? (hard). I spliced it back together by inserting soft alum tube. I think shortening the canopy that way complicates fitting the side skirt around the back. I cut and lapped the side skirts at the rear vertical member of the canopy frame but they want to buckle as they travel the shorter curve. I'm now working my third set of aft skirts. If I knew anything about fiberglass I would try that...maybe later.

Daniel, the pre fab spars are extra-approx $950 extra. You need to contact Phlogiston and they will co-ordinate with Vans. The spar pieces are sent to Phlogiston assembled, and then sent back to Vans in order that your entire wing kit can be shipped together. Many of guys will tell you to save your $950 and do it yourself. Others have told me differently. It will help resale of your plane someday, and I did not want to bother with the larger rivets-too much possible damage in my mind if I had to drill too many of them out.

It does not take much pressure and then drilled and put in a few rivets spaced about 10 inches to hold it in place. I am now waiting on my second set of skirts as I was not pleased with the first set. Go easy when trying to fit these. I would also suggest you remove the rollbar while fitting the canopy.

I'm not sure what you are building, but on an 8A most Home Depot / lumber stores have standard wood molding strips that would go between a floor and wall for decorative purposes. I used a plain strip (no fancy curves on the face) . . . 2 1/4" wide. It tapers from almost a point on one edge to a "rounded" 5/8" on the other edge. These are cut, per plans, and fit inside Van's leg fairings nicely. FMHO, Cutting the stiffeners is best done on a bandsaw with tiltable table (my cheapy Sears does this) because you are cutting along the length of the stiffener at an angle, necking down the piece, plus the cut surface is at an angle so the left/right sides can mate together (this is shown on the plans). As to front/back, apparently it doesn't matter, and mine fit either front or back. Good luck.

There is really not much to it, the holes are all pre-drilled, all you have to do is deburr and polish the pieces, prime it and rivet it together. Several replies have mentioned using a large rivet gun, I used the Avery C frame tool with a 4 LB small sledge hammer (as explained in the manual) and found it worked great. Only had one bad rivet to drill out. Save the money and just build it. For what it's worth, the three biggest hurdles (so I was told) in this project are the spars, the tanks and the canopy. Doing the spars yourself gives a certain confidence to attack the other two later on. I am looking forward to starting my tanks shortly.

Daniel, The pre-fab spar is an option that adds to the cost of the wing kit. It is completely unnecessary as the spar is very easy to build. The fact that Van offers a pre-built one brings up the intimidating doubt that this is an important piece that needs to be professionally built but in fact it is not the case. The spar is very straight forward and simple to build. It doesn't even take that long to do. Save the money, do it yourself. Thousands of homebuilt spars are out there. My comments refer to kits produced after the mid nineties when the wing kits became pre-punched. They must have been a bit more of a challenge before when the builder had to drill all of those very important 3/16th holes. (Comment Jerry?)

Subject: oil cooler doors - final answer
Enough speculation. An oil cooler door DOES work well to regulate oil temperatures and a permanent cockpit controllable sliding door is being installed on my 6A. Previously my oil temps were much too low. Even in an extended climb I would not see much over 140 degrees. Not good! Today, as an experiment, I sealed with duct tape the air entrance to the oil cooler; a 3" hole in the rear of the baffle that feeds cooling air via a 10" length of scat tube to the firewall mounted cooler. After about 10 minutes flying at as high power as I can get up here my oil temps climbed to and stabilized at about 185 degrees. I flew for another 1/2 hour or so including a full throttle 90 mph climb to 14,000 and watched the steady indicator at that perfect 180-185 level. I then landed, pulled off the duct tape, went to have lunch while things cooled a bit, and took off again. Back to 140-145 degree temps. Bottom line - done deal - final answer! Restricting airflow at the intake of the oil cooler does work in regulating temperatures. I also feel that a controllable door is a necessity. If I was content buzzing around the Fraser Valley in similar conditions, a permanent patch would be OK. But, if instead I wanted to hop over the hills into Denver, (4000' lower and 20 degrees warmer), and then face a long climb from 5000 - 14,000 to sneak back over the pass, I'm sure a blocked oil cooler would have caused overly warm temps. There was some discussion earlier that oil does not even go into the cooler until about 180 degrees. This is not true. We do not have thermostatically controlled valves accessing the oil cooler. Its just an open hose and oil flows through the circuit at all times. My hangar partner who flies Falcon Jets for a living said that some advanced turbines have such a feature. And perhaps some bigger more advanced recip engines do too. But our simple little 360s and 320s don't. A sliding door and the cooler intake seems like a simple thing to build probably from scrap laying around my shop. Its the same as the cabin heat door that most of us already have. Problem solved! ________________________________________________________________________________

Just my uneducated speculation here- the common thread in this discussion is that blocking the REAR of the cooler often (but not always) has little effect on cooling efficiency, but covering the FRONT yeilds good results- (recalling several posters who sucessfully duct-taped or had a butterfly type valve in the duct leading TO the cooler) Perhaps there is enough turbulent, cold airflow within the cooler itself when blocked at the exit and exposed at the plenum to effect some degree of heat transfer...

Subject: Re: oil cooler doors solve a symptom not the problem
For those following this thread, the last two posts by Jerry Springer and Bruce Gray bring up a very serious potential problem for RV owner/operators: it appears that very few of our current or future "certificated repairman" have never seen the inside of the Lycoming Engine Operator's Manual, the Overhaul Manual or the Parts Catalog (Mazda and Chevy guys are off the hook, for now.. If you look at the Lubrication diagrams in the Overhaul Manual (2-3, 2-4) it is obvious that a vernatherm valve between the oil pump and the oil cooler (items#1 & 2) in the oil flow journey would allow the the oil temp to reach 180 deg. F before the oil was diverted to the oil cooler. This is an inexpensive part that is very simple to install, BUT it has to be on the engine to work. You can use this neat device called a telephone to order these manuals from Lycoming or call/email Andy at Builders' Bookstore (Yeller Pages). The same device will get you the vernatherm from Lycoming or maybe your local FBO. It's incomprehensible to me how people can spend thousands of dollars and hours on a project and not be able to fork over $50-60 for the material that will actually save their bacon, while they page thru a POH (downloaded from the 'Net) compiled by somebody else and probably has a totally different engine and engine controls/devices.

Subject: Fit of U803
Date: Feb 18, 2001
Hi, RV-8 When doing the final fitting of the legs to the Fuz the left leg torqued up fine but we are having some difficulty with the right leg. When torquing the bolts through the U803 the rear bolt tightens up much sooner than the forward bolt leaving a larger gap between the U803 and U805-1 at the rear than at the front. Also the U803 only contacts the leg at the front leaving a gap a piece of paper can be slid trough at the rear. Thought we had the problem figured out when we noticed the bolt holes appeared to be angled back slightly so that even without the leg in the way we had to have a small gap at the rear between the 803 and 805 to get the bolts all the way through the holes. We cleared the holes with a drill so the 803 could be held flush against the 805 and the bolts pushed all the way through easily. Very little material was removed from the holes. However subsequent fitting of the leg had the rear bolt tightening up early again with the large gap at the rear! Our next move will be to get some bluing compound and tighten the assembly up to figure out where the contact areas are. Any ideas much appreciated.

I've been using a cheap gun called a Docken sprayer. I bought it many years ago and haven't actually seen it lately. It is merely a pistol grip device with a small syphon tube that sits down in a paper cup that you fillwith paint. The cup attaches to the gun via a c clip about 3" in diameter. Once you are done painting you throw away the paper cup and run a little lacquer thinner through the gunand you're done. Not much more than putting the cap back on the spray can. My biggest problem right now is finding paper cups. Everyone has gone to plastic and they dissolve in a heartbeat with thinners and epoxy paints. I have actually written to Sweetheart cup co to see where I can buy the right size. Now that I have the right formula for thinning and pressure I think this is the way to go for easy priming. Not so good for finish painting. Also. you can't tilt it much or the paint will run out the top of the cup.

Subject: F 635 layout problem
Hi list, I'm working on a 6 QB.I've built up the F635 bellcrank for the elevator push/pull tubes and I believe that there is a problem with where it mounts on the F629. If I'm reading the plans right, it should mount through the horizontal angle in line with the rivets which are spaced about 1 1/2" on center and through the (basically) vertical angle on the F628. My problem is that when I lay it out, the location of the hole in the F629 is only about 9/64" from the center of the last rivet. With a 3/16" hole, I'm drilling into the edge of the rivet. Then there is a 3" gap where I'm guessing they thought that the bellcrank is supposed to mount. On the F628 they left several rivets out at the bottom, but the bellcrank layout appears to be between two of the ones they put in and clear by about a half inch so that one should be OK. What now?

I have found I can cruise at 165 knots at 17,500 at about 7.5 gph (fixed pitch prop, O-360, RV-6). I'm happy with that but you do lose some speed with all the time spent climbing. That is about 1 gph less than I would run at around 10,000 feet at 165 knots. I love it up there for reasons other than economy, like great tailwinds and terrain clearance over 14,000 foot mountain ranges. It also gives a sense of security over rough terrain in the glide range it gives you in case of engine problems. As much as I like it, I consider 2 hour legs about minimum to justify it. My web page (under Mountain Tour 2000) has some details about a trip I took last summer where I operated quite a bit a high altitudes.

When I looked at my own data I found my own fuel burn at that altitude was slightly more but could be much less. That is because I have to lean to best power at that altitude to get that much speed. At a best economy leaning the fuel burn would be much better but I don't know what the speed would be. Maybe around 155 knots at 6.5 to 7.0. Not sure. I'll have to try it.

Subject: Re: oil cooler doors - final answer
Enough speculation. An oil cooler door DOES work well to regulate oil >temperatures...... I have a door on the back side of the oil cooler and still have to block off the incoming air to the cooler as the weather cools down. I have one sized blocking aluminum plate for the oil cooler air intake for mild weather and one for cold that stays in place all winter. I leave them off if above 70F OAT. The back door seems to work best for keeping temperatures even in the summer. SO: in my experience the door works and I use it often. If I was to do it over, I would regulate the air coming INTO the cooler rather than air coming OUT of the cooler. My setup, however, works just fine for me. My oil cooler is mounted on a bracket behind #3 cylinder and takes air off the left rear baffle. The gate is controlled via control cable mounted on the left sub instrument panel. 170-180F is the norm, year round.

Subject: Round Head #4 Rivets
Date: Feb 17, 2001
One of the first tough things I remember as a new builder was using the gun and bucking bar setting 1/8 rivets in the various skeletons. I recall that one in my tail was tried a few times and got worse each time. A call (cry) to Vans taught me that I could use a 3/16 bolt with a nylock nut there for the fix. Awhile later I bought a computer and got on this RV List that I had been hearing about. I soon started to catalog neat tips and suggestions. One thing that caught my attention right away was several people discussing how to get these round head 1/8 rivets perfect every time. They were talking about using hockey shin guard tape over the rivet sets on the gun. I thought, hey that's cool but it must be the same as vinyl electrical tape. So I tried it but still got the occasional smile next to a rivet. I then started trying all other different kinds of tape with again the occasional smile. I just couldn't get why those Listers were so adamant that shin guard tape is the ultimate solution. Finally about a year ago I went to Burnaby 8 Rinks and got some of this shin guard tape. It comes in a massive roll around the same width as electrical tape. It is enough for about a hundred builders to complete their projects. It is almost rubbery and stretches evenly when putting on shin guards. It is much thicker than electrical tape. I took it home and low and behold I haven't pooched a rivet since. This stuff is the goods. Perfect rivets every time. Why? I don't know but I do know that every one should try this stuff. I can't say this enough, it makes a difference. Go to your local hockey store and get some, put a small piece on the head of your gun set, it will never slip again. I change it every 5-10 rivets. Use your local yellow pages under "sporting goods".

Boy, this thread just won't die. :-) Actually, this lister has found that both statements can be true. When I found a used O320-E2D for my RV-6A, the oil screen housing did not have a vernatherm by design. During my early test flights, the oil temps went way up. We realized the oil wasn't getting to the oil cooler as well as it should because the oil was flowing back to the sump. With that, I replaced the housing with one that had a vernatherm installed. The oil temps immediately went down to normal for that time of year. BTW, the time of year was winter; so, temps well over 400F should not have been seen. Without the vernatherm, I saw temps rise to almost 450F on a 35F day. Not good. If memory serves me, and it sometimes doesn't do that very well, the vernatherm expands as it gets hot. When it gets hot enough, it closes off a hole back to the oil sump and forces the oil to the cooler. Since the vernatherm is very much like the thermostat in a car cooling system, there must be huge differences in the temps that we'll see in our systems. Mine has to have the oil cooler door so that I can warm the oil because the vernatherm opens the flow to the cooler well below the 180F mark. Others don't. If the vernatherm sticks at the cold position, the oil can't get to the oil cooler and could possibly heat up the oil to dangerous levels, even on very cold days. Mine did just that when there was no vernatherm; so, it stands to reason that a stuck one would have to do the same thing. As I said, my memory banks may fail me; but, that's what I experienced. I did a lot of head scratching before I realized how the vernatherm controlled things and still may have it wrong. I'm not an expert. :-) I'm going to archive this note because others may have similar problems in the future.

Subject: Engine install help
Listers.... Will you allow a non-RV guy to infiltrate with a couple of pi**-a**ed questions? I'm doing the engine install on my 180HP injected Lycoming. First up, a location for the fuel pressure take off. My bendix injector spider sits on the right side of the engine, and came plumbed as follows, looking from the pilots seat forward. The fuel intake is at the 3 o'clock position, low on the spider body. There are what appears to be 7 identical ports, higher on the body. The four that are plumbed for lines to the injector are at the roughly 1,5,7 and 11 o'clock positions. There are two more unused at the 8 and 10 positions, and the one at the 2 o'clock position came with the pressure tap fitting. My question is, can I take the pressure tap from the 8 o'clock position with the same results? I'm presuming that this spider is universal for a 6 cyl Lyc, plus one for fuel pressure, and that they're pretty much interchangable amongst the 7 points. Second question, manifold pressure. Never had one before. I understand that I take the readings from the primer port on the right rear cylinder. Question is, what material can I hook up to that 1/8th" AN fitting? Ultimately, I've got to hook up to some "poly" line into the cockpit, and if I could go poly all the way it would be simple. But I'm concerned about the heat at the cylinder. Solution would be some stainless or copper line for the first few inches like a normal primer install, but then it gets complicated as I try to tie it to something solid, while not having a cantilevered end of the solid line vibrating towards ultimate destruction. Experiences?

Mark, I didn't use the wood stiffeners on either the mains or the nose. I have not had any shimmy on the mains at all to the best of my knowledge. I corrected nose wheel shimmy by torquing the nose axle bolt to the spec in the manual, 7-10 ft lbs. & inflating the tires to the correct pressure. I didn't balance the wheel pants either.

Quick comment: those few who, like myself, have no vernatherm installed, and have taken the cheap n' easy route of plumbing the remote oil filter in series with the oil cooler, will see unfiltered oil as long as the vernatherm is bypassing the cooler circuit. Retaining the oil screen might mitigate this disadvantage somewhat, as you'd always have that system working on the larger particles.

Of course the one of the joys and priviledges of homebuilding is to experiment but... I have to confess, I don't understand the logic behind leaving out the gear leg stiffeners in the first place. They are recommended in the manual, they are easy to do, cheap to do, kind of fun to do (hey, I don't get much of a chance to do woodworking on an RV), and no one who has done them is complaining of shimmy. Okay, they do add 2 or 3 pounds. I mean, if we were talking about spar web stiffeners, no one would be debating their inclusion. (shudders at the thought). Perhaps the manual should be a bit more forceful on some of these "optional" construction details like gear stiffeners. The gear is a part of the secondary structure of the aircraft and you would think the design deserves to be finalized after 25 years of production. Not that I am complaining.

At the last Sun&Fun I attended the Unison forum on LASAR installation. We got to mount and time mags and do all sorts of neat things that helped me when it came time to wire my 6A. The technician was asked about running other wires with the spark plug wires and he said it was not recommended. However, the Mooney on display in the forum tent had some wires wrapped with a spark plug lead for a short distance. The tech said it was probably all right. The spark plug leads for my LASAR system are shielded so in theory there should be no coupling of impulses into nearby wires. However, recommended practice is to segregate the two classes of wires.

In my experience, the Vernatherm is not a "snap acting" type of thermal switch, but a device that begins to move at some temperature and continues to move as it gets hotter. I've personally tested one by placing it in a vice, and heating slowly with a propane torch. It did not suddenly move to a position and stay there, it just started creeping in length until it would not move any further. I'm finding that with my present spin on oil filter housing with vernatherm, the oil temp will not go above 140 degrees in the winter unless I mask off at least 1/2 the surface area of the oil cooler. When this is done, the oil WILL go to 180 degrees and stay there. So, I reckon there must be SOME amount of oil going to the cooler at all times. I vaguely recall reading that having a stagnant volume of oil in an engine lubrication system isn't a good thing, so maybe Lycoming designed the valve to always allow at least SOME amount of oil to make it to the cooler just to keep the oil moving. Just my WAG at it. Brian Denk RV8 N94BD 176 hrs. ________________________________________________________________________________

In the words of the great Van's technical manual: "Shimmy is a nebulous thing". Logic: 1) Van's told me to try it without the stiffeners and see how I like it -- I did and I like it. 2) It saves time and weight not to install stiffeners 3) One function of the gear is to absorb the shocks of landing -- it does this better w/o stiffeners. 4) Hearsay: Nose gear leg breakage has been attributed, among other things, to stiffeners. In general automotive, motorcycle and, I think, aeronautical terms, a shimmy is a side-to-side oscillation of a wheel, usually fixed frequency -- a kind of mechanical resonance. It is usually considered objectionable because it diminishes steering authority and the oscillations can be felt though the frame of the vehicle. In some cases it is divergent in amplitude -- the "speed wobble" sometimes found in older bikes without adequate steering dampers. In the case of my 6A, the gear legs do flex during take off and landings. I think this is their purpose in life. I can't perceive this flexure in the cockpit except for grass takeoffs/landings. Others have observed the motion. However, I can not feel any "shimmy" and the directional control of the plane is positive. I maintain precise directional control with rudder only at speeds above about 7 knots, taxiing included. The only time I use the brakes is during runup and sharp turns while parking. I use about 1500-2000 feet of total runway, after which the speed has decayed to a speed at which I can make a turnoff without brakes. I do land pretty hot -- about 65 KIAS over the threshold. This is with a constant speed prop -- it would not be possible with a fixed pitch prop. Scott McDaniels: How about a word from you on the gear stiffener issue? Does the demo 6A have stiffeners? We listers clearly need some advice from the experts!

[The Canard Aviators's Mailing list] A separate regulator is desired when the battery and the regulator are in different locations. The charging voltage required by the battery lowers as its temperature increases. In automobiles, the battery and the alternator are usually in the same temperature environment, ie, the engine compartment, hence no problem with the regulator being located in the alternator. However in my RV-6A and the VariEze, the battery is in the cabin, and that is where the regulator should be. The regulator is temperature-compensated for the varying requirements of the battery. If you have an alternator with an internal regulator when the battery is in the cabin, the battery will be undercharging by about .5 volt. This could leave your battery in a low state of charge at any given time. This would probably show up when starting on a cold morning. You can reduce this problem somewhat by ducting outside air to the alternator to keep its temperature down, but you don't have any control over this. It's better just to put the regulator near the battery. Garth Shearing VariEze and 75% RV-6A ________________________________________________________________________________

When I found a used O320-E2D for my RV-6A, the oil screen housing did not have a vernatherm by design. During my early test flights, the oil temps went way up.

The oil temps immediately went down to normal for that time of year. BTW, the time of year was winter; so, oil temps well over 200F should not have been seen. Without the vernatherm, I saw oil temps rise to over 225F on a 35F day. Not good. If memory serves me, and it sometimes doesn't do that very well, the vernatherm expands as it gets hot. When it gets hot enough, it closes off a hole back to the oil sump and forces the oil to the cooler. Since the vernatherm is very much like the thermostat in a car cooling system, there must be huge differences in the temps that we'll see in our systems. Mine has to have the oil cooler door so that I can warm the oil because the vernatherm opens the flow to the cooler well below the 180F mark. Others don't. If the vernatherm sticks at the cold position, the oil can't get to the oil cooler and could possibly heat up the oil to dangerous levels, even on very cold days. Mine did just that when there was no vernatherm; so, it stands to reason that a stuck one would have to do the same thing. As I said, my memory banks may fail me; but, that's what I experienced. I did a lot of head scratching before I realized how the vernatherm controlled things and still may have it wrong. I'm not an expert. :-) I'm going to archive this note because others may have similar problems in the future.

Ed, I went out and looked at my setup. I have no rivets near the holes. In fact the holes for mounting the bellcrank appear evenly spaced between the existing rivets on both the F628 and the F629 angles. I'd double check where you are laying out your holes. The plans didn't give dimensions as to where the holes should be, just the drawing. I remember some consternation while figuring out exactly where to locate the holes. If the rivet spacing is screwed up on your F629, it wouldn't be the first error found on a QB.

F before the oil was diverted to the oil cooler. Wow, what a great idea. You should write Lycoming and tell them to redesign the engine so it is configured as you describe, then it would work the way YOU think it should. Here in the real world where the rest of us live, the oil cooler bypass valve is NOT located "between the oil pump and the oil cooler". Instead, Figure 2-3 on page 2-2 of the (current) Lycoming overhaul manual shows that the oil cooler bypass valve is in fact installed in a path between the input and the output connections leading to the oil cooler (in other words, the bypass valve is in parallel with the oil cooler). By the way, Bob Ohnmeiss (Lycoming tech support) told me that the vernatherm (oil cooler bypass valve) is installed stock on the O-360 A1A as shipped from Van's. The vernatherm ("Valve Assembly, Temp control oil cooler bypass", Lycoming part number 75944) is part number 44 on figure 15, page 2-10 of the O-360-A series parts catalog. Bob told me that even though the parts catalog doesn't show it, part 44 is installed into the bottom of part 29, the Oil Filter Base Assembly. >This > is an inexpensive part that is very simple to install, BUT it has to > be on the engine to work.

What am I missing? The vernatherm is in *parallel* with the oil cooler, not in *series* with it. The vernatherm does not shut off the flow of oil to the oil cooler, it provides an alternate path circumventing (somewhat) oil flow through the oil cooler if the oil is already too cold. When the oil is too hot, the vernatherm restricts the circumventing path, forcing more of the oil through the oil cooler. >Are > vernatherms standard on some/all engines?

Thanks, Bob >> Bob, Only bevel the corner where the two skins meet right behind the tank skin on the spar flange. This is only about a 2" square area. Don't bevel the skins full length or it could weaken the splice. The goal is to make the area where the skins overlap each other and rest on the main spar, to be at the same level as the tank skins. I beveled them by filing the skin thinner. I placed the skin on my workbench so the corner to be filed was in the corner of my workbench. Then using a file, I filed the skin in that corner only, down to where it was about as thin as the aileron skin.

The bulkheads are made with a softer aluminum that what the rest of the airplane is so it allows for some adjustment.

Now using you hands you can slightly "dish" the shape of the fwd bulkhead so that the flange moves aft by the amount that you moved the aft bulkhead.

From: bcbraem(at)home.com Subject: Re: RV-List: oil cooler doors solve a symptom not the problem For those following this thread, the last two posts by Jerry Springer and Bruce Gray bring up a very serious potential problem for RV owner/operators: it appears that very few of our current or future "certificated repairman" have never seen the inside of the Lycoming Engine Operator's Manual, the Overhaul Manual or the Parts Catalog (Mazda and Chevy guys are off the hook, for now.. If you look at the Lubrication diagrams in the Overhaul Manual (2-3, 2-4) it is obvious that a vernatherm valve between the oil pump and the oil cooler (items#1 & 2) in the oil flow journey would allow the the oil temp to reach 180 deg. F before the oil was diverted to the oil cooler. This is an inexpensive part that is very simple to install, BUT it has to be on the engine to work. You can use this neat device called a telephone to order these manuals from Lycoming or call/email Andy at Builders' Bookstore (Yeller Pages). The same device will get you the vernatherm from Lycoming or maybe your local FBO. It's incomprehensible to me how people can spend thousands of dollars and hours on a project and not be able to fork over $50-60 for the material that will actually save their bacon, while they page thru a POH (downloaded from the 'Net) compiled by somebody else and probably has a totally different engine and engine controls/devices. Boyd Braem N600SS flame away--at least it will increase your chances of staying alive Boyd, This is not at all meant as a flame but just to point out that it is much more complicated than you imply. I am very familiar with the schematic in the Lycoming overhaul man. I am also familiar with the fact that it doesn't tell the whole story. If you ever sit down with just an accessory case cover and look at were oil passages go you can finally get a good idea about what is going on. Now it has been a while since I did this my self so every thing that follows is from memory (meaning I could be totally wrong) but I think it is pretty close. First of all most Lycomings that RV builders are using probably have a vernatherm installed (unless they are really old). Some may have a washable filter screen and many probably have a spin on filter adapter but either one of these can and probably are using a vernatherm. One of the big misunderstandings about the vernatherm is how it directs oil to the cooler (Lots of stuff in the archives about this. Some by me, and some by others). When the engine oil gets up to a temp matching the value of the vernatherm that is installed the vernatherm grows in length an closes off a by pass path. If you are using a spin on adapter this also closes the bypass for the oil filter (thick cold oil doesn't like to flow through a paper filter element very well). What this means is that there are two paths for the oil when it is cold (through the filter and cooler or through the by pass path that allows it to flow around it. When the vernatherm elongates and entirely closes off (assuming the seat surface and the end of the vernatherm are in good shape) the bypass, forcing all of the oil to go through the filter and the cooler. Here is the problem... when the oil gets somewhat warmed up (say 120 deg F.) it is warm enough to flow through the filter, but the temp is not high enough for the vernatherm to do any regulating yet. Since the cooler is mounted in the warm engine compartment, maybe even directly attached to the baffles which get heated up by the engine cyl., it gets warmed enough to warm the oil in the cooler and the lines. This in turn means that there is now much less resistance to oil flowing in the cooler circuit, even though it has a by pass path to flow through since the vernatherm has not yet closed the bypass path. More simply...a vernatherm does NOT keep the path to the cooler closed until the oil warms up. What it does do is close the path which allows the oil to not flow through the cooler. If you want to test for your self... run your engine on a cold day, just long enough to get the oil temp. up to about 120 deg. Then disconnect the oil hose that returns to your engine from your cooler. Put a cap on the open fitting on the engine. Now start the engine and run it for about 5 seconds. I think you will have a big mess to clean up (but maybe I'm wrong). The main problem is that until you can get near the vernatherm temp, you have two paths for the oil. The oil will tend to take the path of least resistance but not all of goes that way. Because every RV (and engine) is a little different sometimes this little bit of residual cooling is just enough to keep the temp from ever getting high enough for the vernatherm to do its regulating job. Devising a means to variably block air into the cooler seems to work well for alleviating the problem though I highly recommend that you not do anything to deal with the problem until you are flying and you find out that you really have a problem (many builders do not, as attested to here on the list), and then only after you verify every other possibility (gage error, etc.).

Bob, Check the archives for a procedure that I used and worked great. I can't remember the poster's name, but there was a thread I started sometime around the end of the year regarding this very topic. One of the replies was to cut a small square out of the inboard skin (that's the one that lies under the outboard skin per plans). The inside of this square is even with the outboard skin, so they lie flush together on the spar. The original post even contains a diagram. Works great! Looks great!

Thanks, Bob I offer my posted reply to a similar question back in December 2000: "e I tried both methods of getting a single layer where the skins meet. I tried overlapping them - I used my finishing palm sander; I think a belt sander might be too aggressive. The joint was not very good even though I started thinning some distance from the actual overlap area. On the bottoms, I figured few would get on their backs and look at that joint, so I trimmed them to a butt joint (notched one side). You know what? That was a better looking joint and truly _was_ a single layer thick. I was so impressed that I did my other top skins the same way, and I recommend it. Cut your notch and trim a bit at a time, and then use a scotchbrite wheel on the die grinder to finish. You can get the joint so it is barely noticeable. "e If you check the archives (use the word "chamfer" as well as "bevel") you will get a lot of hits and some more view points.

Subject: Lycoming on Vernitherms
The following are questions I asked Lycoming regarding Vernitherm operation and oil temps. My questions are in lower case. The answers are in upper case: my 0-360 A4M installed in an RV-6A, has very low oil temps (just over 140, even in long climbs). I have been advised that the vernitherm may be stuck in the open position thus allowing oil into the cooler, even when it does not need to be. because I am unfamiliar with this part please answer these questions. THE VERNITHERM IS ALWAYS OPEN, UNTIL THE TEMP GETS TO HOT!!! 1] is this a likely scenario? NO! 2] Is the vernitherm adjustable or will it simply need replacement? If adjustable, how? NO! 3] I was also advised that there is an AD on this part. If so, where can I find a copy? THE FAA. 4] Another person suggested that the vernitherm also restricts or adjusts oil flow into the screw on oil filter. Is this true? NO. An alternative or additional step might be to construct a cabin adjustable door to open and close air intake into the oil cooler; Your comments on this? THE VERNITHERM ONLY CONTROLS MAX OIL TEMP. IT HAS NOTHING TO DO WITH LOW TEMPS. THE AIRFRAME CONTROLS THE LOW TEMPS. JAMES MATTHEWS TECH REP TEXTRON LYCOMING Also, I've been looking for a copy of the relevent AD.

This has been a pretty interesting thread to say the least. It appears those trying to control the air flow across the cooler itself have been correct. Lets add another wrinkle to this solution, instead of controlling the air, how about installing a ball valve right at the oil cooler which would direct all, some, or none of the oil either through the cooler or divert back into the return line. This valve would be controlled from the cockpit via a cable. Just like the valves that control the hot water that flows to the heater cores of our millions of automobiles.

I sure don't get a warm fuzzy feeling about having yet another knob in the cockpit to adjust something that seems like it should be automatic. Doesn't there exist a reliable thermostatically-controlled valve that could control the flow of oil through the oil cooler, to do what a lot of people seem to think the "vernatherm" should be doing? From the sound of the Lycoming reply, it sounds like the "vernatherm" is sort of an emergency backup in case whatever the airframe mfr put in series with the oil cooler got stopped up. If so, then maybe they were assuming a thermostatic valve? I don't know about anybody else, but I think a hundred-dollar-or-so valve that let me concentrate on flying the plane rather than messing about with the engine would be a safety enhancement, especially if there was already a backup device to slow it down from destroying the engine if it failed. I guess I'm biased. I earn my living automating stuff a thousand times more complicated than a thermostatic valve, and have make it cost under $10 most of the time. It's galling that to get a reliable airplane I'm having to install so much 1940's-vintage control stuff. > -----Original Message----- > From: Im7shannon(at)AOL.COM [mailto:Im7shannon(at)AOL.COM] > Sent: Monday, February 19, 2001 10:40 AM > To: rv-list(at)matronics.com > Subject: Re: RV-List: Lycoming on Vernitherms > > > > This has been a pretty interesting thread to say the least. > It appears those > trying to control the air flow across the cooler itself have > been correct. > Lets add another wrinkle to this solution, instead of > controlling the air, > how about installing a ball valve right at the oil cooler > which would direct > all, some, or none of the oil either through the cooler or > divert back into > the return line.

Kevin, After mulling this thread over, controlling the air to the oil cooler seems like the right way to go. Besides the benefit of bringing all the oil up to a temperature that will drive off moisture, a inlet air control valve has the secondary benefit of redirecting cooling air no longer going to the oil cooler back to cool the cylinder heads.

Subject: Balanced wheel pants benefits and How to land this thing!
From: Rick_Smith(at)tivoli.com
Date: Feb 19, 2001
02/19/2001 02:53:31 PM My 180 hp. RV-6 (N1150S) has 215 hours on it now and it has been quite an enjoyable learning experience. Concerning gear leg shimmy and balancing wheel pants there are a couple observations I can relate. Some gear legs shimmy fore and aft while taxing and some don't. If I have greater than 30 psi in the tires they shimmy all the time while taxiing with or without wheel pants. At 25 psi shimmy very rarely occurs and it is much easier to land. A wooden stiffener bonded to the gear leg may prevent the symptom but it appears the causative factors are brake disks that are not perfectly true and hard tires on smooth pavement. Balancing the wheel pants for and aft so the CG is at the axle does a couple neat things. One is it prevents a torque load from being applied to the mounting points when the wheel gets deflected vertically by a bump. If you operate out of rough hard fields you will notice that the mounting attachments get torn up and the pant mounting develops play allowing the pants to tilt up and down. Theoretically, balancing may also cause them to be directionally stable in flight just like an airfoil which may reduce drag some minuscule amount. My second set of pants are not balanced and I have not experienced shimmy and since they fit so close to the wheel (quarter inch gap all around the tire) I don't go into dirt strips anymore but it sure is fast. Now for a question I have been struggling with. How do you wheel land a RV-6 taildragger. My normal attempt scenario is to approach at about 85 with half flaps, level off as close to the runway as possible and try to kiss the runway with the tires and relieve back pressure or try to feed in forward stick to plant it. Hasn't worked yet!.. As soon as the wheels touch it bounces into the air before you can feed in forward stick to suppress it. Should I just feed in forward stick while holding off and fly it into the concrete while saying "damn the decent rate, I wanna wheel land"? Last week I flew in a F1 Rocket with Titanium gear legs and it soaks up the decent rate like oleos and wheel lands perfectly. Feels like you couldn't bounce it if you tried. Apparently the Sonex guys also use titanium gear legs and they also claim similar rebound dampening performance. If that is really what I am experiencing my next venture may be building a set of RV-6 titanium gear legs. The gear legs on the F1 are not bent but use a welded axle fitting that lets you adjust the wheel alignment with shims. Very clever. Sorry for the long post but not being able to land my own plane is getting embarrassing. Regards, Rick ________________________________________________________________________________

"Doc, it hurts when I do this." Doc says; "don't do that." You will get many opinions but mine is that it is never NECESSAY to wheel land an RV. That includes a 20 knot gusty direct crosswind. That being said I understand why one would want to be able to do it. I can do it five times in a row perfectly and the next one will completely humble me. Mostly I don't try it anymore. I think the only trick is that the descent rate must be very low or you will be relaunched halfway into orbit. There is nothing more impressive to a passenger than a really well executed one but the potential for complete humiliation is far too great. My only go around to date was with a new passenger and a botched wheely.

Subject: Help! RV-4 Fuse Bulkhead Line Up Problem
OK, I have a problem and can't figure it out. I was wondering if anyone else had this problem. On my RV-4 Fuse, the .125 AL angle on F413 does not line up with the .063 angle on F404. These AL angle should meet approx. 90 degrees and have one rivet attaching them. They are about 1/4 off or so and thus I cannot get a rivet between them. I have the F413 aligned with the bottom of the firewall and the bottom of F404, but the top side appears to be 1/4 too tall thus not permitting the AL angles to line up. I am having the same problem on the back side, the AL angle on the F415 does not line up well with the .063 angle on the back of F404. Again the F415 is lined up on the bottom of F404 and F407, but it too appears too tall as the AL angle on F415 is higher than the attaching angle on the back of F404. I assume that is a very important rivet as it ties the heavy AL angle from the firewall to the wingspar and then back to F407. Is it safe to just rivet the rest of the rib bulkheads but not the AL angles together? Any help/advice would be greatly appreciated. Thanks -Mike was doing good on the fuse, now frustrated.... ________________________________________________________________________________

There are a boatload of pictures but the initial pages load pretty quickly so you can pick and choose which ones you want to see. http://bmnellis.com/FlyIns/TwinCity.htm BTW, in case you haven't noticed, I got my own domain name now so my website address has, hopefully, changed for the last time. If you have my site linked or bookmarked please make the appropriate changes so you'll get the latest information and updates. I've also updated the site to reflect more consistency from page to page and improve the navigation structure. I appreciate your patience while I've gone through some recent ISP changes. Thanks also to Bill Vondane for helping me through this process.

Subject: Re: Lycoming on Vernitherms
It actually does make sense. If you've followed this l-o-n-g thread it has been explained that there two parallel paths for the oil to follow. One path is through the cooler and filter, the other is via a bypass passage the size of which is controlled by the vernatherm (sp?) valve. Hence the minimum or low oil temps are controlled by the airframe i.e. how much cold air passes over the cooler etc. and the maximum temp is (hopefully) kept in check by the vernatherm (sp?) whose function causes ALL of the oil flow to be through the cooler when the temps get up to it's set point. Thus at lower oil temps the vernatherm is wide open and the oil has two paths to follow. Hopefully enough bypasses the cooler for the temperature to rise to acceptable levels. If not then reducing cooler efficiency by blocking airflow comes into play to help raise temps. Thus the "winterizing plate" installed on most aircraft in the north where we get WINTER. At higher oil temperatures the vernatherm gradually, as the temp rises, reduces those choices of flow path to one. Namely through the cooler thus hopefully keeping a fixed ceiling on what temperature the oil can attain by forcing all of it to be cooled.

Subject: Tank screws - lose fit
Date: Feb 19, 2001
I'm trial-fitting the fuel tank and was surprised to find that the tank screws that fastens the tank to the main spar are not difficult to fasten - in fact, they almost seem too easy. This is the first time since I started the RV-8 that I've encountered 'easy' plate-nuts. They are not lose, but I bet my 7 year old son could fasten them. I used AN509-8R8 screws and K1100-08 plate-nuts. Anyone else? Are RV-8 Wings ________________________________________________________________________________

The smallest hose they sell is 1/4" so I used that although you can get 1/8" as well I believe (from Aircraft Spruce?) which would probably be better. At any rate the flexible hose gives me a better feeling than the copper or whatever. Got the fittings for the port from Vans as well.

Hi Kevin: Little late replying on this, generally speaking the cost to overhaul is about the same as a new pump. The pump for the 0320 & 0360 run around $ 200.00 US. If you call 1-800 822 3200 they can take care of you. I believe they are located in North Carolina, they supply most of the pumps that come up our way or get one from ACS the part # 41271 and the price is 193.00 in their current catalog.

Yeah I had this problem too and I know others have had. Its actually pretty close (depending on the thickness of the f-glass in that area). I used a bench mounted disk sander to sand down the mounting surface on the receptacle by 1/32" or so before riveting on; problem solved.

Subject: vibrations (floor stiffeners)
Date: Feb 20, 2001
I installed these brackets a couple weeks ago... I did all 4 stiffeners even though only the outboards show on the plans. In discussing this with my local RV bunch we finally snapped to the fact that Van's standard center console ties the inboard stiffeners to the spar. If you leave out the console as I did, then add the brackets to the inboard stiffeners. They make a noticeable difference in oil canning. I crawled underneath before installing the brackets and got a fair amount of flex & oil canning when I pressed up on the skin. After installation, it's almost non-existent. Plus, it's gotta help withstand my 10+ bubba factor.
