I discussed this with the guy who was doing the inspections in Ottawa before I got too far into the project. He suggested that I leave corners of the HS and VS skin on one side unriveted so he could peel them back a bit and look inside with an inspection mirror and a flashlight. I think I left about 10 rivets at the ends of the spars, and a similar number along the root and tip ribs. For the elevator and rudder, he wanted to be able to look the riveting on the stiffeners, so I only riveted one side of the skin to the spar and ribs.

Wow, thanks for the quick responses! To all who have asked, I live in London, Ont. I should have mentioned that in the first email. It seems to be the consensus that one side should be left clecoed, and that is what I was leaning toward but it seemed like the inspector would then only be seeing half of the work (the other half being the open side). This puts my mind to ease and I can now get back to building. Thanks again Carl ________________________________________________________________________________

Let this be a lesson to new builders, don't let this happen to you! Make your tanks easily removable by painting them separately, and NOT painting the screws. This could have been a half day job to do both tanks.

Subject: Re: Fuel Tank SB Experience
Larry, The Titeseal consistency does not seem to change markedly with time. I don't believe that there is any sort of "cure". It is a viscous "honey-like" consistency. When removing the plates after four years, the gaskets easily separated from the tank and plate surfaces. I refilled both tanks within an hour of re-mounting the inspection plates. I checked the area of the seal as I filled the tanks and two days after with no sign of leakage. After two days without leaks, I re mounted the wing fairings. I used new cork gaskets. The old gaskets that I removed were permeated with the Titeseal. I believe that the gaskets serve a purpose to hold the Titeseal, allow it to extrude around the screws and that the saturated cork provides a seal conforming with the two mating surfaces and is a mechanically strong barrier to leakage. I, too, would recommend to new builders to paint the tanks separate from the wings, or at least avoid painting the screws. That avoids the anxiety of unscrewing painted screws. I was able to remove the tanks, clean the Titeseal residue, conduct the SB on the pickup tube nut, replace the inspection plate, replace the tank with all its screws in about 3-4 hours per tank. A second pair of hands is helpful to navigate the tank clear of the tubing and avoid scratching the wing.

Hello, I noticed that a couple builders had a problem with the button head cap screw stripping. I experienced the same problem but in a more accessible location, and even that was very difficult to remove. My solution for the tank access covers was to use socket head cap screws. The head is actually knurled, and sticks up about .125 so if the hex drive does strip there is something there to easily grip and back it out. McMaster Carr carries them.

Listers, Since this is the hot topic right now, here's a suggestion. Buy a few new no. 2 Phillips dry wall screw driver bits. Get the kind that have the serrations at the tip. These will bite into the screws and not strip them out. They can be taped into a 1/4 inch socket with a turn or two of electrical tape and turned with a ratchet handle. There's my $.02 worth.

I need some advice from other un-muffled RV owners who fly in and out of TOA. I'm heading south for the Halibut Derby, and would like to park at TOA for a couple of nights while fishing. I heard that you can get fined for exceeding noise limits, but I was unable to find out how much it might cost if caught. I'm sure it's more than I want to pay. Anyway, My RV-4 has an O-320 with Vetterman's crossover system, and it's very loud. How do I get out of TOA without getting cited? Should I full power climb over the airport as steeply as possible, then pull it back by the boundary? Where are the sensors?

Charlie: Sounds like you have a bang up engine. The only real problem we see with running the engine past TBO is that the longer you run it the more wear occurs on critical components and the more your overhaul might cost. I wouldn't buy a core with an unknown history for o'h or exchange. The core you have sounds like an excellent candidate for overhaul, and that would be our recommendation. You won't really know what the condition of the internal components are until the engine is in teardown, but if your cases, crank and cam are repairable, you are making a good investment in going with a quality overhaul shop. Make sure that the engine will be built to Factory New Limits and that all SBs and ADs are in compliance. Good luck! Rhonda Barrett-Bewley Barrett Precision Engines, Inc. 2870-B N. Sheridan Rd.

As I recall, orig builder that I bought it from, let the engine sit coupls years without running, and knew the history. Anyone have experience with this quandry?

From: windsaloft(at)rmisp.com
We've been flying the RV for a few years now, and today in the hangar I stumbled upon...........the ol' squeezer! I had no idea I still had this. CP-214 Original Chicago Tools Squeezer. It has the quick change pins and a C-Yoke with a 1.25" opening 1.5" deep and accepts 3/16" shaft dia rivet sets (none included). THe head was ground down to 3/8" thick to help us get all the tight rivets on the RV-7 wings. It built one RV-6A in Casper, WY (that is who I bought it from) and then built a set of -7 wings. It has been sitting in the WYoming hangar now for two years. It worked flawlessly for me on the wings, and I oiled it and squeezed it at the hangar today and still works as well as always. I'll guarantee that it works when it arrives your location or I'll refund your $$. $225 plus shipping via UPS ground, insured from Zip 82520. Email with questions. I wanted to put it in this community first before going the ebay route.

I wouldn't buy a core with an unknown history for o'h or exchange. The core you have sounds like an excellent candidate for overhaul, and that would be our recommendation. You won't really know what the condition of the internal components are until the engine is in teardown, but if your cases, crank and cam are repairable, you are making a good investment in going with a quality overhaul shop. I own a PA-28-180 with 2140 TTSN. I have replaced one jug about 200 hrs ago. This is a 1965 aircraft. It has always been inside and maintained better than recommended. I would not even consider exchanging it for an unknown case etc. Especially with the crankshaft problems LYC is having these days. My C/S might be 41 years old, but they sure didn't have any AD notes on them every year! If you have a clean, tight, good running engine I would not even consider anything except an overhaul by someone you personally know and trust.

Scott, I took these apart and re-assembled (but for a different reason). No it was not difficult; the larger 1/8" rivets are easy to drill out without disturbing the hole by using a smaller drill and working up in size. The only issue you may have will be to squeeze or pound the rivets upon assembly - I have a larger (double piston) squeezer that handles the 1/8" rivets. I took mine apart to make them look nice. -- Larry E. James Bellevue, WA HR2 ________________________________________________________________________________

Jeff, My wing kit is mid 90s vintage and there is a revision on the bearings from the pressed in (small) bearing to the com-3-5 (large) bearings. According to Ken the smaller one were pressed in but they were concerned with them coming out so they went to the larger bearings that are sandwiched (captured) between the hinge plates and riveted together thus requiring disassembling to replace.

You can gently squeeze some of the flutes with a pair of seaming pliers (two flat plates welded to a pair of vise-grip jaws) or something similar. Heck, even putting the rib on edge on your wooden shop table, and hitting the flute gently with your dead-blow hammer would probably flatten them out adequately. The fluting process doesn't stress the material so much that a little "unbending" will hurt it. Be gentle, and spread the unbending out over the entire rib, and the part will be just fine. -Rob ________________________________________________________________________________

I've done that, and to un-do it I just turned my fluting pliers at as close to 90 degrees as I could get and squeezed a bit to flatten the flute a bit. Or sandwich the flute between a couple of scraps of metal and squeeze it with pliers (or whatever). It doesn't take much. You'd have to flute and (totally) flatten the same spot more than a couple of times before you have to worry about fatiguing the metal.

Builders, I take this opportunity to give an ATA-BOY to Cleveland.

Hi All, The FAA finally showed up this morning, looked over my RV-8 and my paperwork and bestowed upon me an Airworthiness Certificate for "Miss Izzy". The guy was here for less than 20 minutes! He never got closer than 4 feet from the airplane and scanned my 80-page test program in less than 10 seconds! I wasn't counting on an inspection as I have had two visits from EAA Tech Counselors and my friend and RV-8 owner, Jerry Cornwell (AI) spent about 2 hours with a flashlight and mirror looking over the plane this past Sunday. The flight went without a hitch. The engine ran smooth, cool and powerful. The EFIS and radios worked flawlessly and the plane flew straight as an arrow. The only "correction" needed is a bit of right rudder trim. I only flew for about 25 minutes, established a stall buffet at 54 knots clean, 52 knots with half flaps and 49 knots with full flaps. After a low pass of the airfield with the smoke system billowing I touched down and did my best to suppress the cheesy RV grin. It didn't work. I'm still grinning! The plane has a Lycoming IO-360 built by Mattituck with Aerosport fuel injection, dual Lightspeed electronic ignitions and a Whirlwind 200RV constant speed prop. The panel has dual GRT EFIS, SL-30 comm/nav, Garmin 327 transponder, Trio autopilot with altitude hold. Interior is by Flightline Interiors, belts from Hooker and paint is Imron applied in my homemade paint booth. I'll be tearing up the 50-mile radius around Gold Hill Airpark (NC25) for the next 40 hours. Hope to have Phase I done in time for Sun-N-Fun. Thanks to Steve Glasgow for lending a third hand whenever needed and providing lots of back seat time in his own RV-8. I'll be seeing you all a bit more now that I have wings!

Subject: Re: Blended Airfoil 72" vs. 74" (I have the answer, kind-a)
I have the answer, I got it from Hartzell. Its prop data on the HC-C2YK/F7666. It is similar but it does show some trends based on dia. The nod goes to....... Climbing (slower speed) = 74" Cruise, High speed & higher RPM = 72" Bottom line Low speeds 74" Higher speeds 72" When I say better, I mean one prop may be 1/8 th of one percent better, to may be 1/2% to 1% more efficient at best for a particular flight condition. When I say efficency I don't mean performance. You may throttle (rpm) back and get more prop efficency but you get less thrust and thus less speed. In general RPM is a big factor on efficency at cruise speeds for any diameter. If you play to the 72" you would climb at a faster speed. Efficency may increase but rate of climb goes down. TINSTAAFL. If you're a racer, want to go fast the 72" is better. In climb at slower speeds the 74" prop is better. The 72" seems to always enjoy a slight edge in cruise and even more at higher speeds and RPMs. The 74" seems to alwasy enjoy a slight edge in climb and even more at slower speeds Better means if you fly side by side at the same RPM one plane may go 1/2 mph faster or climb 50 fpm faster. Slight, not big differences, but differences. What to buy? I like going fast but I like having the extra 2" of prop material. At least you have something to trim if there is tip damage, but than if it was 2" smaller dia you might not get the tip damage in the first place? Sorry can't tell you what to do, but I am leaning to the 74" for more rework material if it was me. The BA prop has the extra 3.5 edge on the HC-C2YK any way, and about 3 mph over the WW RV200 prop, so you can give 1/2 mph away and enjoy that extra 50 fpm climb. :-) Specific question email me off line.

The difference may be more than performance. The 72" diameter is the minimum diameter of the Hartzell propeller. Damage the tips on a 72" diameter Hartzell, and the complete propeller is scrap. If the 74" diameter blades are damaged, and can be trimmed to a 72" diameter, or greater, then the blades would be useable. Unfortunately, the hub is still scrapped.

Hi Jim, The general laws of aerodynamics say that the larger diameter will give better low speed thrust and the smaller diameter will be better for high speed flight. This may not hold true depending on how Hartzell shaped the blades, but all other things being equal it should work this way. Whether there's a measurable difference between these two diameters is arguable. I got the 74" in part because it allows you to cut off 1" of each tip in case of damage and still be airworthy. Of course it might be more likely to get damaged if it's longer to begin with so this may be a toss-up. If I had to do it over, I'd be inclined to go with the smaller diameter because during full power runups to set the low-pitch stop, my 74" prop sucked up a lot of sand and now the paint looks like crap on the leading edges. It's pretty close to the ground on the nosedraggers and 1" might make a measurable difference in how much trash your prop picks up on the ground. Or just flip a coin and pick one : ) --Mark Navratil Cedar Rapids, Iowa RV-8A N2D 11.3 hours flying... ------------------------------------------------------ From: "Jim Thorne" <rv7a(at)cox.net> Subject: RV-List: Blended Airfoil 72" vs. 74" Does anyone have any information on pros and cons on choosing a 72" vs. 74" Hartzell blended airfoil prop?

A tip to avoid over fluting is to lay the rib flat on the worktable after marking each fluting location and kneel down so your eyes are at table level looking under the rib toward the light from the open door. As you squeeze the fluting pliers you will see the rib sink down to the flat tabletop and the light coming under the bowed rib will disappear as it flattens out. Just gently move around the rib deepening some flutes until no light comes underneath the now straightened (flattened) rib.

Getting to town and back was nearly as exciting as departing OSH 2005. :-) Seriously, Phil's home airport is a fine stop, and the car did a great job of wallowing to lunch and back.

We are talking about 0.1% to 2.0% diffence, real but small. The 74" has a real advantage at Vx or Vy speed in climb. The 72" has a real but smaller advantage in high speed curise.

I didn't have this problem, but I truly believe fear of flying is all about a lack of knowledge regarding flying. If she would be open to learning from someone else, openly as to why airplanes fly, maybe she would warm up to some pitch hitter flying courses. I am sure it isn't that easy, but gotta start somewhere.

Subject: Re: Spouse afraid to fly
>>Divorce Two<< That's not good. I don't have so much an answer as a couple of questions. As a former non-flying wife (I'm a flying non-wife now, but that's a different story ), my resistance was from fear of what I didn't know about flying (which was a lot). I grew up in an airline family, but a Cherokee was a lot different, to me, than a DC-10. Before I made the decision to learn to fly, I watched AOPA's Pinch Hitter tape quite a few times. Or, it could be fear of economic ruin due to his interest in flying, or perhaps, fear of her not being #1 in his eyes. She may not know that her husband can love flying and her at the same time. Once I polled a few friends (a female thing) and figured out that if all these other people could do it, I could too (and didn't need to know calculus to fly), the belief I had changed from "I can't" to "I can." She may be terrified of losing him in an accident, particularly in a (forgive me) "homemade" plane. Some people are unable to put words to these fears because they're further afraid of not seeming to be the person they want to present to their spouse. Or, it could be symptomatic of other, more general, problems in their relationship. The idea of respecting and supporting your spouse's interests, even if you don't share them, is often lost on the non-interested spouse. If it wasn't flying, it would be some other interest that she didn't share. It takes a particular brand of emotional generosity to be able to do that, and some people haven't gotten there yet. So, there are a few questions from my female point of view... hope it helps or points him in the right direction. best, Cory Richard Scott wrote: > >I was showing a newbie my project when he mentioned that his wife didn't >like to fly, didn't want him flying and was totally against him building a >plane, but he was going to do it anyway. > >There used to be an RV around the area named "Divorce One" and I see a >"Divorce Two" in the cards if he can't get his wife to change her views. > >Some of you guys must have had this problem--how did you deal with it? > >Did you get her to accept your flying & still have peace in the family?

Date: Mar 18, 2006
I started flying 20 years ago, just months after getting married. My wife was reluctant at best, but was proud of my accomplishment in getting a private license and acquiesced to fly with me occasionally. She got a little enjoyment out of it, but her fear and apprehension were always in the background. Just for the heck of it, I suggested she attend a 99's flying companion seminar. Best thing she could have done, and I recommend it highly. She felt MUCH more at ease in the airplane now that she had an idea of everything that was going on. It also whet her appetite to learn more about it. When it came time to build an RV (10 years ago) she wasn't against it, but wasn't thrilled either. However, when we talked about the ability to get away on 2-3 day vacations that were impossible by car (and impractical by rental Cessna) or to see her family more often (16hrs by car, or 3.5hrs by RV) she became a believer. We've been flying it for 8 years and the only thing we fight about now is who's doing the flying. My advise, get her to a 99 class, go slow, and show her the end result (destinations that she will enjoy) and she might just end up enjoying the process as well.

Funny this thread should come up. I was just on the phone yesterday with a college friend's wife in her mid-50's who has refused to fly her entire life. She grew up in a isolated coastal town of Eureka, California and has lived her entire life there. Never had any reason to travel by plane so her fear matured over the years. Fast forward to this past January when cherished only child finishes college and married a guy from Mississippi two months ago that she met through the internet. Suitor's family owns a multi-generation family business of which he is becoming a part . . . never to leave Mississippi. My friend's wife cannot maintain her close relationship with her only child and hopefully upcoming grandchildren without flying back and forth from California to Mississippi. She bit the bullet and flew back for the wedding in January. She said she had white knuckles throughout the takeoff (luckily the death grip was on the seat, not my best friend from college's wrist), she had tears streaming down her cheeks by the time the jet reached altitude, but she says once the plane is cruising she didn't feel much anxiety at all. She is quite happy to know she can get through a flight after all. So . . . get your kids on the internet to marry someone far away. Motherly survival instinct will take over her fear of flying!

Guys, I have 15.8 hours now on my RV and my new Hartzell is still slinging out some grease....just enough to see a few fine streaks down the blade and get drops of grease on my windshield, cowl, and wings. I believe Hartzell says that if you let the prop sit in the box for over 18 months the seals will dry out and need to be replaced because they'll leak. Of course when I ordered my prop I knew I'd be flying in a year so this wouldn't be a problem for me. Yeah right. It sat in the box for two years before I first ran the engine... I have a hard time believing I'm the only one like this so I'm wondering, has anybody else experienced this problem? If so, did it ever go away? I'm not concerned about it from a safety perspective--I can lube the hub occasionally and make sure it doesn't dry out in there--but it's a real pain to clean up especially in the canopy. If anybody's replaced these seals, can you remember how much it set you back and where you had the work done?

Subject: Nosewheel bearing question
From: Mark E Navratil <czechsix(at)juno.com>
Guys (those of you with a nosedragger), I still don't have my wheel fairings on. This weekend during preflight I noticed some black goo, tar-like stuff oozing out around the rubber bearing seals on my nosewheel. It did not appear until I had about a dozen landings on the airplane. Since the grease that was in it originally was the normal amber color I was a bit surprised to see this color, and also a bit surprised to see it leaking out as it had been perfectly clean up until this point. Anybody else seen such a thing? I also checked the rolling friction of the tire and it is still REALLY stiff to turn by hand. I know that when a wheel is properly installed there should be enough load on the bearing to provide friction....i.e. it should not continue to spin around freely after you give it a whirl by hand. But from the first time I installed the nosewheel--properly torqued per the plans with a calibrated wrench--it seemed excessively stiff to me. I remember the plans said that it would be this way until it was broken in a bit. I don't know how long that should take but I checked the nosewheel on my hangar mate's new -7A (with fewer hours than I have) and his wheel turned much easier. I tried loosening the nut on the axle bolt and that made it turn more freely but then I noticed that the spacers were spinning too. I torqued it back up and now it's ridiculously stiff again. My hangar mate's -7A has the wheel pant installed so I can't see whether the spacers are spinning on his. I called Vans and Gus said that it's quite common for people to call and complain that the spacers have been spinning instead of the bearing and galling up the fork assembly. He suggested that I could put some screws in through the fork into the spacer to keep them from spinning. This would allow me to reduce the pressure/friction on the bearings, but he cautioned against reducing the torque on the axle bolt too much since Matco calls out 7-10 ft lbs for this assembly. Personally I think the whole design is a bit iffy from the perspective that there's a very small margin between having enough pressure to keep the spacers from turning without so much pressure the that rotational friction on the bearings/seals is excessive. It makes me wonder how many people are flying around out there with the wheel pants on, completely unaware that the spacers are spinning away while the bearings are doing nothing. On the other hand, if the rotational friction is excessive it *may* have contributed to some of the bent nose gear incidents that have occurred in recent years. It's pretty scary watching the nosegear at high speed, even during a good landing....the more rotational friction, the further the gear is going to bend back/under when it first makes contact at high speed. I think I'll disassemble the whole thing, check the bearings for overheating, repack them, put screws in through the fork/spacer assembly, and tighten it up until it feels "about right". Any comments/experience from others with this assembly would be appreciated. FWIW, I understand that the -6A's had a different design (which some local RVators consider to be superior to the current design...).

Mark, I had this 'problem' as well with my Hartzell. My didn't have anything to do with 'shelf life'. All I did was remove the spinner and retorque all the hub bolts. A couple of the bolts had been removed to fit the spinner and these were the culprits in my case. Once the bolts were retorqued the slinging ceased for me. Also, I'll mention that (in my case) the grease was building up inside of the spinner before it worked it's way out of the prop root cutouts and was able to fly back to the windsreen......make sure you check the inside of your spinner real good and remove any grease that may be present before you replace the spinner.

I had this same problem (spacers turning by the torque of the seals) when I first flew my -7A. At first I was going to put in roll pins like a Cessna 150, but decided on a different solution which has worked very well. I made a steel sleeve about 3/4 inch OD to put between the bearing spacers on the axle bolt inside of the wheel. Once this sleeve was fine tuned to the correct length, I could tighten the axle bolt to full torque without actually having the bearings support the bolt tension. To support the sleeve while taking the nose wheel on and off, I have a length of 3/8 inch rod that gets pushed through when installing the axle bolt. This rod is a little shorter than the distance between the forks. Dan Hopper RV-7A Flying 148 hours ________________________________________________________________________________

Mark, good advice from Rick, I had the same experience. There was a pile of grease inside the spinner, presumably from outside the seal, but within the hub. This grease worked its way out of the prop during the first handful of hours, but then slowly crept out of the spinner. My prop did, however, need resealing around 500 hours/3 years. If you should need to reseal, there are two shops in this general area. One is Maxwell at Crystal airport in Minneapolis, and the other is Midwest Props in Kenosha, WI. Both of these shops will tell you that there are two problems with Hartzell factory props - one is that they use a non O-ring seal, some sort of non circular section seal.

If so, this is a terrible design. The 6A has a stout, hollow aluminum tube taking the load between the two larger hollow cylinders which directly touch the fork. This is as Dan has described that he did on his 7A. On my 6A, I could tighten the axle bolt until it breaks, and the wheel bearings will not be affected. Please tell me that the new design doesn't simply have the bolt mash the bearings with nothing in between, although I heard this also from a local builder. This simply isn't acceptable. Put a thrust tube in between, and use some shim stock to tweak it in. Van makes the best product available, but sometimes I feel they put more emphasis on hiring people with airplane building experience and not engineering. It is easy to imagine bad things happening when things in that assembly deflect under load...

Steve, The spacer is made of mild steel rod. Aluminum would be OK, I think. Actually, I had help. The idea should be credited to a local craftsman named Carl McCain. He first used the idea on an RV-9A. From another post I see that the 6A used something similar, and that it is good engineering practice. Glad to see I wasn't flamed right away!

After the residual grease stopped slinging within the first few hours on my RV-8, CS Hartzell, I had about 140 hrs when it started slinging again. I took the spinner off and could see the grease trail coming from the parting surface on one side between two of the three bolts. I called Hartzell, told them when I started flying it (still under the one year warranty from first flight) and how many hours I had on it, and they paid for a reseal under warranty at Jordan Propellor.

Well, I do hate to have to ask another question on the heels of my last one (un-fluting), but here goes. Countersinking the rudder (9A) TE last night (R-916), it became apparent after a couple holes that the holes are enlarged by the CS. There is no way to CS to the correct depth without enlarging the holes. I've been trained that countersinking should *never* cause the hole to enlarge - if it does, the material is too thin - but this seems to be a special case (piece sandwiched between two skins for double-flush riveting).

Too far forward? No, the edge was prepunched #40 and then was match-drilled. The holes are just where they're supposed to be. Well, then, I'm entirely confused about this because, as I said, there is NO WAY to countersink to the proper depth without enlarging the holes some - and it's not a trivial amount, either.

The wedge was pre-punched ? I'm assuming only the skins were pre punched and you match drilled into the wedge. I think what Paul is saying is that you need to re-position the wedge further AFT relative to the skins, that way you will be countersinking into the thicker section of the wedge. Which may necessitate you replacing the wedge. I had a a similar issue although perhaps not as pronounced. I bonded my trailing edges with T-88 epoxy which made them a lot stronger.

When Mark sent the original post, I dragged out dwg. 62 from my preview plans and it shows the older style Cleveland wheel- there is a long aluminum "axle" (U-609) that is trapped between the fork halves and allows the bolt to be properly tightened, and thus no side-load on the bearings. My nosewheel sounds just like Mark's, with the separate spool on each side. Does anyone have the actual drawing (not preview) that shows the current (Matco) configuration and does it show a spacer between the two spools?

(spacer omitted?) By the way, I just had to replace my nose tire due to wear (300 hours- does this sound a bit soon?), which obviously is accelerated by the tire rotational resistance.

> Too far forward? No, the edge was prepunched #40 and then was > match-drilled. The holes are just where they're supposed to be. Was the AEX wedge drilled from the factory, or did you match drill it using the holes in the skin? If the wedge itself came drilled from the factory, then you're right...not much choice in the matter. If the wedge had no holes in it when you started, then it's possible you located it too far forward when you drilled it...which shifts the holes toward the thin end of the wedge...but it's NOT a huge deal. Take a look at the flap brace on the RV-7/8 and you'll see that it gets countersunk between the dimpled wing skin and the untouched flap hinge. Those c-sink'd holes end up huge. It's OK because that layer is sandwiched between other layers. Take a look at the left elevator rear spar, trim tab spar, etc. Same deal. Stuff gets c-sunk and enlarged, and it's OK because it's sandwiched between at least two other layers that don't have enlarged holes. I may be mistaken, but I believe Van's mentions this scenario in the construction manual. In any case, your rivet's manufactured & shop heads are both bearing against un-enlarged material. My 2 cents is, rivet that sucker and press on. If you have any doubts, call Van's Builder's Assistance (503-678-6545, no wonder how I can just spout that from *memory*!) and they'll probably tell you the same thing.

Mark, The shimmy problem is usually due to too free of swivel of the castoring nose wheel. My gear leg had a problem that would lead to abnormal wear causing this joint to become loose. The collar at the top was not square to the bearing. I forget the exact arrangement right now, but I filed a long time getting it to meet over the whole area. Part of the bend of the gear leg actually went below the collar -- not a perfect situation! I have never had a shimmy problem when the castor nut was tightened to spec. High tire pressure would also aggravate shimmy. I run about 32 psi. This seems high but I have the 200 hp angle valve engine.

It's less pretty, but it's going to be a lot stronger. If you're countersinking both sides of that wedge and finding that the countersinks are meeting each other, you'll have a knife-edge around the hole, which isn't condusive to long rivet life. On the Elevator, at least, you could put the square heads on the underside. -Rob ________________________________________________________________________________

Thanks, Dan. These were mostly my thoughts as well (both rivet heads are secure and the TE is just squeezed in) but I thought I should ask. (Having finally ruined my first part recently (and a skin at that), I think I may be "erring" hard on the side of caution lately.) This section of the instructions doesn't speak to this issue, and, I just reviewed section 5 as well, on countersinking, and didn't see it addressed there either. Perhaps it is in there somewhere. Or maybe this is something that's assumed to be obvious. :-} Paul -----Original Message----- From: owner-rv-list-server(at)matronics.com [mailto:owner-rv-list-server(at)matronics.com] On Behalf Of Dan Checkoway Sent: Tuesday, March 21, 2006 10:41 AM Subject: Re: RV-List: Rudder Trailing Edge Countersinking > Too far forward? No, the edge was prepunched #40 and then was > match-drilled. The holes are just where they're supposed to be. Was the AEX wedge drilled from the factory, or did you match drill it using the holes in the skin? If the wedge itself came drilled from the factory, then you're right...not much choice in the matter. If the wedge had no holes in it when you started, then it's possible you located it too far forward when you drilled it...which shifts the holes toward the thin end of the wedge...but it's NOT a huge deal. Take a look at the flap brace on the RV-7/8 and you'll see that it gets countersunk between the dimpled wing skin and the untouched flap hinge. Those c-sink'd holes end up huge. It's OK because that layer is sandwiched between other layers. Take a look at the left elevator rear spar, trim tab spar, etc. Same deal. Stuff gets c-sunk and enlarged, and it's OK because it's sandwiched between at least two other layers that don't have enlarged holes. I may be mistaken, but I believe Van's mentions this scenario in the construction manual. In any case, your rivet's manufactured & shop heads are both bearing against un-enlarged material. My 2 cents is, rivet that sucker and press on. If you have any doubts, call Van's Builder's Assistance (503-678-6545, no wonder how I can just spout that from *memory*!) and they'll probably tell you the same thing. At least that's my 2 cents...hope it puts you at ease. )_( Dan RV-7 N714D http://www.rvproject.com ________________________________________________________________________________

However my situation may be a little different. On my first flight, just seconds after liftoff, grease (at the time I thought it was oil) began covering my windscreen. I made a quick trip around a shortened pattern and landed it by looking out the side as the grease had obsured my forward vision. Found out that Hartzell had left out the ball in one of the grease fittings. Got a new fitting and serviced the prop, but ever since then I get streaks on the windscreen. I may have overserviced it. I skipped one service interval and put less in now, and it seems to be getting better, but still just a little grease after each flight. It's not enough to make me change the seals.

Sherman, Are you going to alternate the direction of the rivets? That seems like a good method. In fact mine would look awful if I hadn't done that because I didn't use any adhesive. That was a mistake. As it is, I have a slight "sine wave" if you look closely at the rudder. It isn't that bad but it could be better. If I hadn't alternated the rivets it would be curled about 4 inches! I set the rivets with a squeezer as far as possible, then finished with the gun -- a flush set against my back riveting plate. It seems to me like a squeezer with dies ground to that angle would tend to bend the rivets.

Dave: This information is over a decade out of date, so take that into consideration. However, when the Canadian air force evaluated ANR headsets in the early 90s they found that the systems available, which were designed for fixed-wing aircraft, were not suitable for helicopter crews due to the very different frequency distribution of helicopter noise. It's possible that the information your son was given is valid for turbine-powered choppers but not for piston-powered airplanes.

You might the RV-9 List archives also. This issue comes up from time to time. The RV-9 wedge comes prepunched and countersinking will enlarge the holes. I match drilled the wedge holes into a piece on 1/8" al strip that I bought at Ace Hardware. I put clecos in about ever 10th or 12th hole to keep it in place and the strip provided a hole for the countersink pilot. Flip the wedge and do the other side then clamp the wedge, pull the clecos and csk the remaining holes. On the other side of those holes you can csk by hand. You will have the same problem on the main spar for the tank attach screw nutplates but you can just use a short piece attached with clecos thru the #40 nutplate attach holes and the strip will provide a pilot hole.

Subject: Re: Tite Seal
Walt, I am including below what I wrote earlier (March 12) about this subject. I filled my tanks as soon as I re-installed them on the wings. Richard Dudley ========================================================================== The Titeseal consistency does not seem to change markedly with time. I don't believe that there is any sort of "cure". It is a viscous "honey-like" consistency. When removing the plates after four years, the gaskets easily separated from the tank and plate surfaces. I refilled both tanks within an hour of re-mounting the inspection plates. I checked the area of the seal as I filled the tanks and two days after with no sign of leakage. After two days without leaks, I re mounted the wing fairings. I used new cork gaskets. The old gaskets that I removed were permeated with the Titeseal. I believe that the gaskets serve a purpose to hold the Titeseal, allow it to extrude around the screws and that the saturated cork provides a seal conforming with the two mating surfaces and is a mechanically strong barrier to leakage. I, too, would recommend to new builders to paint the tanks separate from the wings, or at least avoid painting the screws. That avoids the anxiety of unscrewing painted screws. I was able to remove the tanks, clean the Titeseal residue, conduct the SB on the pickup tube nut, replace the inspection plate, replace the tank with all its screws in about 3-4 hours per tank. A second pair of hands is helpful to navigate the tank clear of the tubing and avoid scratching the wing.

I didn't notice much enlarging of the holes, but maybe I set the microstop too shallow? Dunno, but I clecoed everything up and the dimpled skin set in fine. I was so pleased with the fit I decided to try using epoxy instead of proseal . After mixing up a batch of West Systems with a slow hardener and making a slurry with Cabosil to a thick consistency, I used a small brush and painted it on to the skins at the trailing edge. I layed the skin onto the bench with the wedge clecoed to the trailing edges and followed the steps spelled out in the plans. Yes, I did this by myself where the directions call for an assist to fold the skins over while you reach in to rivet the clips to the ribs or stringers. I used a "sky hook" to hold the top skin overhead while I slowly lowered it into place and proceeded with the blind rivets. Yep, it was a handful, but kinda fun and I didn't get too much epoxy all over! After I finished up the riveting, I clecoed the whole trailing edge, very little oozed out needing cleanup, and weighted the rudder down to let it dry overnight. Next morning it was rock solid, clecoes easily popped out and I cleaned up the holes. I back riveted the whole length against a length of 1 1/4 angle iron clamped to the edge of the workbench. Except for my overzealous gun work, (really dislike those little smilies!) in a spot or two, it came out really great. I may spot fill the shop heads and lay a layer of glass over the edge and really clean it up smooth. Anybody think I should worry about smoking rivets working through?

John Huft ********************************************************** Copied below is a slightly edited version of the latest information received direct from Race Director Eric Whyte (the excellent website is still saying the entry forms will be available before the new year 2006 - http://www.airventurecup.com ). Bob Axsom ******************************************************************* Hi Guys, Sorry it has taken so long to get back to you, I was in the USVI and the internet connection was really slow so it was kind of a read only situation for a week. Not a bad place to be stuck on a 6 day layover though! So here is the deal, we need to find our own sponsors. We need any and all leads you guys can come up with. The good news is that EAA is giving us our own separate checking account so all money we raise goes directly to the race. No ... Tax as in the past. Also if we should raise enough to have money left over at the end of the year all the better it goes into the kitty for the 2007 race. So once we raise money for the event it stays until we use it up or stop having the race. We are obviously looking for a large sponsor if there is interest but we are also looking for many small level sponsors. There are very few companies that are willing to spend $15,000 to sponsor an Air Race but we are hoping it would be easier to find ten companies that are willing to donate $1,000 to $5,000. The other part of the bad news is that EAA is charging us full face value for the wristbands so that is something we will need to look at. I dont necessarily agree with but that decision was made above my level as they say. The good news is we have one sponsor already on board that has committed to the lunch and breakfast in Dayton. Yes those are not the most critical of items we are looking for but they were offered and I am not going to look a gift horse in the mouth. ( The Sponsor is Commander Aero the FBO that hosts us) EAA is staying on to provide the insurance coverage and some publicity. We have control over the website and they have agreed to run a blurb about the website in Sport Aviation and also on the e-hotline. I have been really bogged down with work recently I was on the road 22 of 28 days in February, so I have not been able to get the race staff together yet. I dont see that changing anytime soon. I just got summoned for jury duty and crew scheduling blew a gasket and is frantically trying to get me out of it because apparently they cant live with out me for two days. It is nice to feel appreciated I think! In the e-mails you guys sent me several of you mentioned possible leads for sponsors, I speak for the entire race staff in saying we need all the help we can get. Since I am on the road nearly continuously at this point e-mail is the best way to contact me. I will keep you all posted.

Subject: Tite Seal Update
Guys, I accidentally found out something interesting about Tite Seal. As I indicated in my previous post, I used it a few days ago on my left tank. Today I gassed up the left tank and checked my fuel gauge and the @#$% &*'d thing wasn't working. Checked the wiring, didn't find a problem, then drained the tank to remove the float/sender. To my surprise, after the last drop of gas had drained, Tite Seal began oozing out of the drain opening! So, I then removed the cover plate and using a mirror, saw there was an accumulation of tite seal in the bottom of the tank. Naturally, this has me concerned about the merits of tite seal versus proseal. Sure, Proseal makes it hard to get the cover off, but if you apply too much tite seal as I obviously did, it's a tad unsettling, since the stuff can run down the inside of the tank and possibly even get into the fuel line. I think I'm gonna clean this goo out of the tank as best I can then use proseal and pray for no more SB's. Some food for thought for those using tite seal.........

Dave, With this simple modification, you can easily and precisely adjust the elevator's counterbalanced weight to accomodate any current or future balancing requirements such as might be confronted after the application of paint. I did this on my -8 empennage kit and hopefully is of the same general design as your -7. What I did was install a 1/4" nutplate through the forward tooling hole on the outboard rib and by simply stacking a combination of area washers though a bolt on the opposite side of that rib, precise balancing is quickly adjusted. http://img99.imageshack.us/img99/5788/img0010500io.jpg http://img61.imageshack.us/img61/7093/img0011506ek.jpg Rick Galati RV-6A "Darla" > > David Karlsberg wrote: > > > So, I am working on the Right elevator.

Subject: Rudder Trailing Edge Countersinking
Last night I successfully riveted the trailing edge of the rudder using the hand ground angled rivet set. I glued the edges together with 3M 5200 Marine adhesive (white alcohol clean-up) 5 days ago, and clecoed the rudder to an aluminum angle. I inserted rivets in alternate holes, clamped the aluminum angle with side grips to keep the edges straight and act as a back-up bar, and hand squeezed the rivets with a straight rivet set until the set just touched the rudder skin. This squeezed 4 layers of metal. I then finished the squeeze with the angled set using the same setting pressure for all the rivets. A straight set was in contact with the factory head and all the angle was placed on the shop head. I inserted the second half of the rivets facing the opposite direction and stood the rudder with the trailing edge up. I the squeezed these rivets with the angled set in one squeeze. The rivets set straight and did not buckle to the side as the pressure was straight on the rivet axis. The trailing edge is straight, and only took about an hour start to finish.. My thoughts are: Gluing the trailing edge with a straight edge helps maintaining alignment. I suspect the secret to maintain a straight edge is uniform rivet pressure (harder to do with driven rivets, at least with my skill level). I am now wondering if using a universal set would work as well leaving a rounded head in the dimple. If I had a 3/32 universal set I would have tried one to see. This is becoming more fun actually finishing components!!

I had worked out a way to be able to easily unbolt the counterweight on the first RV-8 that I built, so I could replace it with a heavier one when I painted the plane. I happened to mention this to one of the Van's support people when I called about something else, and they almost laughed me off the phone. They said if it really needed to be that precise, there would be RV's falling out of the sky left and right every day. Their suggestion at the time was to leave it just a bit heavy to compensate for future paint, then quit worrying about it. The next RV I finished was an RV-3. Guess what, no counterweights at all on an RV-3 elevator, and you couldn't even tell it in flight. My advice would be to do whatever makes you feel comfortable, but realize that a small imbalance won't cause a problem under normal operating limits. Now if you plan to set your Vne 50 kts past the recommendation, then you're on your own anyway.

This will reduce the amount of stick force required to pull a given amount of g (or increase the amount of g achieved for a given stick force), and would make the aircraft a bit more delicate to fly when pulling g, especially at aft CG.

FWIW, I balanced my RV7 elevator after I painted it. I have kit #47 so things may have changed as of today. But with my kit I had to remove a lot of lead from the counterweight. I did it by drilling one hole after another until I got it perfect. If I were doing it again and I planned to paint the plane, I would paint before making weight adjustments.

Subject: Re: Rudder Trailing Edge Countersinking
Date: Mar 24, 2006
Hi guys, (second and third paragraph have suggestions for improvement) I recently did the rudder for my RV7 (which is the same rudder as on the RV9). It had the predrilled aluminum extrusion (AEX) wedge and prepunched skins. I match drilled them, dimpled the skins, and created a simple jig for c-sinking the AEX wedge. The AEX holes did get enlarged, but the dimpled skins fit well. When I prosealed the skins together, the dimples from one skin hit the dimples from the other skin causing the skin to bulge slightly apart at each rivet. It's counterintuitive...you would think that the skins would be pinched tighter at the rivets. The end result is that if you place your fingers on either side of the trailing edge and run them along the length of the rudder, you can feel a little bulge at each rivet. If I were going to do this again, I would do everything the same as before, but I would file down the dimples just a little to allow the two skins to actually sit flat against the AEX wedge instead of the dimples hitting each other and causing these slight bulges. I followed the instructions in the manual exactly. By back riveting halfway and then setting with a mushroom set, the rivets came out really well. It's hard to keep from bending the rivet over, so I probably drilled out 1/3 of the rivets and put them in a second time so they all look good. Good luck, Mike Cencula ________________________________________________________________________________

What does your MP gauge read when the engine is stopped? It should read 29 or inches, depending on field elevation.

Hi Guys, I've finished fitting the baffles on an O-320 on an RV-9A. I've established a clearance between 3/8" to 1/2" inch between the baffle and the top cowling. How high should the airseal material be above the tops of the baffle pieces before it gets folded? I'm thinking about 1 1/2 inches. Is this in the ballpark?

Hello all, I would like to hear from you if you're a builder who has successfully installed and flown an alternative engine in your plane. I'm compiling a builder's roundup for Kitplanes magazine, and am looking for an installation that's flown for a minimum of 300 hours, and is currently flying. For the builders that we profile, the magazine will also be able to pay you $100 for the write-up. I'll be at Sun 'n Fun until late morning on Friday (April 7), so if you fly in, I'd be happy to take the photos there. If not, we would also need at least 2-3 good photos, including a close-up of the engine and an overall shot of the aircraft. Additional photos would be great, and all photos will be returned. If you have digital photos, it is very important that they be high-resolution, at least 300 dpi. I have a list of specific areas to address if you'd like to participate, but we can handle that off-line.

Subject: Request for Info
Hi Folks, I recently posted a request for info from listers with flying RV7, RV7a, RV9, RV9a, who had a specific engine/cowl/induction/prop configuration. I received little in the way of response--probably because the con fig I have is somewhat unique. I am making another request for data which will apply to a much larger group. I am working on a performance issue and would like to have comparative data. The data, based on some postings by folks who obviously have a much greater knowledge on engine inductions than do I, will tell us something about the average efficiency of our induction systems. If I get a good response I will compile the data and post it to this site -- it would therefore be helpful in evaluating the performance of our individual systems against a group average. The sample data should come from either nose gear or tail wheel flying RV 6-7-9s equiped with Vans cowl and FAB induction system and carburated 0360s or 0320s running a fixed pitch propeller. You will also need both rpm and mp gages. The data necessary for the analysis is as follows: 1. mp indicated on engine gage prior to engine start 2. line up on runway prior to t/o and hold brakes, wot, and note mp and static rpm 3. just at lift off note mp and rpm 4. mp and rpm at 100-400 ft agl.--watch for traffic!! Please note in your response whether you have the 0360 or 0320 engine and the type of engine gages (Vans, AF2500, etc) Your help is greatly appreciated and maybe we can all learn more about the performance of our RVs.

More replies to non-issues than real problems? Not unexpected. Mechanical, structural or building problems often have one or two right/better answers--very digital, 0 or 1. An issue of 'the price of gas' is not directly a building issue, but it is certainly plane/pilot issue, hence fair game. Most of the answers are, in fact, opinions or thoughts on the matter. There is no digital answer, this is an analog issue. There is value in wide ranging input to a policy problem like the price of gas, as there should be. The input ranges from interesting, to logical, to 'what are they thinking'. Nonetheless, they all are important to formulation of quality opinions on an issue, rather than blind allegiance to our preconceived notions that may have been formed based on limited, or faulty, information. I view this forum as an educational tool, not just a builder assist program, though I'm sure other's hold well-owned opinions to the contrary.

Subject: Tip Tanks
Date: Mar 26, 2006
Ok, I've got the tip tanks installed and flying. What I'm finding is that I'm overflowing the main tank vents (Van's standard main tank vent implementation) in flight when all tanks have been filled. I confirmed that the tip tanks can flow fuel to partially filled main tanks OK. But when all the tanks were filled, gas poured out the main tank vents while in flight (actually emptied both tip tanks...). Blue stains all over the belly of the plane, and obvious gas smell while in flight (probably coming in through the flap extension holes....). The main tank vents have 45* bevels facing into the airflow (towards the front of the plane, per Van's plans). They are located just behind the firewall (per Van's plans). The tip tanks have the 1/4" tube vent bent into the airflow. I've installed 1/4" tubing extending 2" down from the belly of the plane and bent 90* into the airflow on the main tank vents. That has stopped the main tank venting (when all tanks have been filled) while in flight. But it now appears that the fuel is not moving from the tip tanks to the main tanks while in flight (when I inspected the main tanks level on the ground, both were down about 2" - both tanks had been selected individually while in flight - and the tip tanks were not down significantly). This problem seems to be a mis-balancing of the vent pressures between the tip tank and the main tank. It makes me question why there shouldn't be just one vent for BOTH the main and tip tank on each side.... Has anyone had to resort to this technique? Has anybody else had this problem? Is so, what was your solution? I'll be at Sun 'N Fun on 4/7 - 4/8 but will be commuting back and forth to the Daytona area each day. I'd like to compare notes with anyone that has tip tanks installed.... Fred Stucklen RV-6A N926RV ________________________________________________________________________________

Fred, Are you using check valves to prevent the fuel from going from the mains to the tips? If not, the single vent scenario would work for you - otherwise you could pressurize the mains if your only vent was in the tips. I've been fretting this scenario too - my initial thoughts were to use just enough of a vent to the mains to prevent the outflowing that you are experiencing. I also have my plumbing with a slight incline upward to my check valve so it is the high point in that part of the system. I'll need pressure to get the fuel to go from the tips to the mains. Don't know if it works yet....I'm just getting started on firewall foreward.

I had about 500 hours in various RVs before installing the Tru Trak and I am 100% convinced that it is indispensable for XC flying in these aircraft. Your fatigue level is immeasurably reduced and it allows you time to scan for traffic and easily handle other cockpit chores. I have flown my Tru Trak in severe turbulence and it handles such conditions as good as the zillion dollar auto flight system in the B757 I fly for work. It tracks a GPS course easily within .07 of a NM. Save up and buy one!!!! BUT.... You might also hold off and see what Tru Trak is coming up with this summer.

Subject: Re: Tip Tanks
Date: Mar 26, 2006
I've installed the check valves per the plans from Jon. I'm thinking now that taking the check valve out (&replacing it with a union), capping off the original main tank vent, and only using the tip tank vent for both tip and main tanks. The problem with the dual vent method (Jon's approach) is one of balancing the pressure equally on both vents. If the main vent pressure is higher than the tip tank vent pressure, the tip tanks won't drain properly in flight. If the main tank vent pressure is less than the tip tank vent pressure (by at least the "head" within the main tank vent line rise) then the tip tank vent pressure pushes the fuel out the main tank vent (and once it starts, a siphoning action will maintain the flow).... Evidently, that is a valid possibility as I lost 18 gals of fuel from the tip tanks out the main tank vents within a 20 minute flight. The belly of the plane was quite "blue"..... If the tip tank is the ONLY vent for both main & tip tank (by replacing the check valve with a union), the fuel would run freely to the main tank (but at some reduced flow rate). Any excess pressure buildup in the main (while on a hot ramp, or a slip condition in flight, or an uneven parking condition) would push fuel outwards to the tip tank. I guess there would be a possibility of not being able to get the fuel back into the main tank as quickly as it is needed when the main tank was near empty. That might lead to a fuel starvation issue. I would think that this would not happen in straight & level flight, only under abnormal conditions. Would the behavior of this type of fuel system be acceptable for all realms of normal utility class flight? Big question..... that can only be resolved through testing or others experiences.....Would parking on a slanted ramp (where the tip was lower than the main) move all the fuel to the tip, and could that lead to a fuel starvation issue if one were to take off with that low tank selected? Probably.... Is it a real threat (because the highest level tank should have been selected prior to takeoff...)? Good questions....(are these "real" safety issues????) As long as the main tank and tip tank are separated with a check valve, the main tank requires a vent. Otherwise, it would not have a method to vent excessive pressures while sitting on a hot ramp. Jon eluded to the use of an electric solenoid in his plans (but warned that it's use would cause slower fuel transfers). This would also be a doable solution, but changes the overall timing of fuel transfer. Instead of emptying the tip tanks first, the mains would have to be run down to a level where they would accept the full tip tank quantity. Tip tank vent pressure would definitely have to be higher than the main tank vent pressure, otherwise, the tips would never empty. I'm also exploring the idea of BOTH tanks being vented to the SAME vent. There are two possible solutions, both requiring another 1/4" vent line in the wings. The main tanks could be vented to the tips (is this any different than removing the check valve??) or the tip tanks could be vented to the existing main tank vent.. I guess this is why I've asked the question as to how successful others have been with this installation.....Have there been any fuel problems in any other installations? Has anyone really looked at the problem? I sure wish that Jon was monitoring this list.... Maybe he could comment on how his system should work.... I'm not sure what I'm going to try next. Right now, with the main tank vent pressure greater than the tip tank vent pressure, I'm not loosing any fuel. The tip tanks are not usable in flight, but will drain into the mains once on the ground. Fred Stucklen RV-6A N926RV 545 Hrs second offender... Subject: Re: Tip Tanks From: Ralph E.

Having said that, here are some thoughts. I'm not fond of using only gravity feed for the aux because with my leading edge tanks, the aux won't drain completely until the mains are down to maybe 5 gallons. I want the aux tanks empty early, rather than late in the flight to get back to 'normal' handling as soon as possible. Your tip tanks may empty earlier, with more fall to the mains. Some ultralite guys have had success by plumbing their mains vent directly to the aux feed & using the aux vent as the only vent for the entire 'system'. (You could achieve the same effect by simply sealing the mains vent.) The mains then suck the aux tanks dry while still almost full. Obviously, the filler cap needs to seal air tight for this to work. This idea is tempting, but I hate to change anything on the original vent/flow path as designed into the plane if I don't have to. Highest on my list at the moment is to feed the aux tanks to a 2nd Van's type selector, which would feed the unused port on the existing selector. It sounds more complex at 1st, but has the advantage of leaving everything in the original design totally stock except the plug in that last port of the original valve. It might (emphasize *might*) be possible to eliminate the 2nd selector by feeding both aux tanks to a small sump in the belly to feed the original selector. The sump *might* keep the engine from sucking air when (not if) one aux tank empties faster than the other. Hopefully, this potential problem would only be encountered at altitude in cruise flight & recovery would be quick & only mildly upholstery-pinching.

Those guys who are selling the tubular aux tanks plumb the aux tanks through facet fuel pumps which act as check valves. When you've burned enough out of the main, you refill it from the aux using the electric pump which has a light that comes on after a set amount of time to remind you to turn it off. Just another idea.

Having said that, here are some thoughts. I'm not fond of using only gravity feed for the aux because with my leading edge tanks, the aux won't drain completely until the mains are down to maybe 5 gallons. I want the aux tanks empty early, rather than late in the flight to get back to 'normal' handling as soon as possible. Your tip tanks may empty earlier, with more fall to the mains.

(TruTrak was very nice and only charged me the difference). During ground testing, there were several problems. The folks at TruTrak were very nice and had me send it back to upgrade the software to fix the problems which it did. (I am a bit disappointed that there is no serial port to upgrade the software and that I had to remove the unit and send it back--lets hope I don't have to remove it again). In further ground testing, I could not get the vertical navigation to link up with my GNS480. To make a long story short, it turns out per my last conversation with them that they have not been able to get it to work because Garmin did not include a centerline signal in their unit and have no plans to change it. So, it turns out I didn't get what I paid for. I'm not sure how it performs otherwise since the first flight is about a month or so away.

Subject: Tip tanks (more)
Date: Mar 28, 2006
I also plan on using tip tanks on my RV7A. And I've also been pondering this fuel feed question for at least 12 months. This is a very good thread and timely for me. I've seen many solutions (actually flying) for feeding fuel from the tips and I've listed a few below with a few of my comments on each. Just my opinion of course and I welcome further feedback. 1. Floating "cistern" style valve in main tank. Opens valve to allow fuel to flow from tip to main when fuel in main gets down to a certain level. Advantages: Fully automatic..nothing to do or remember. No chance of fuel being vented from mains vent. Disadvantages: No suitable valve available on the market as far as I know which means you have to manufacture it. May be prone to mechanical failure. A nightmare to get to if it fails. Conclusion: Not for me. 2. Five way fuel selector. Andair sells them. Enables selection of either mains or either tips individually. Advantages: 100% access to auxiliary fuel guaranteed. No check valves to fail. No problems with differential vent pressures between mains and tips. Disadvantages: You'll have to run the tips dry to empty them which means the engine will stop. If you're not careful and you leave the tips selected you might lose engine power at a bad time. Conclusion: A potentially dangerous set-up if you get distracted. Using all useable fuel in flight essentailly means running a tank dry. Not for me. 3. One way mechanical valve. Andair sells them and they are fitted between the tips and the mains. Advantages: Very reliable in terms of fuel availability and nothing to remember. Disadvantages: Can result in fuel overflowing through mains vent if pressure differential not precise. Once flow starts it may be assisted by siphon effect. When the plane is parked with full mains, fuel will seep back through the one-way valve and refill the tips. This can be a problem for accurate fuel measurement. It also precludes any aerobatics until the fuel can be pumped back into the mains in flight. Also requires a well sealing fuel cap to prevent fuel loss at the cap (that excludes Vans caps which are terrible). Conclusion: Popular solution but not without problems. 4. Electric fuel pump between tips and mains. Advantages: Fast fuel transfer. Control of flow. Disadvantages: Requires electric power to gain access to aux fuel. The pump introduces another failure point. If the mains are full when the pump is switched on then all the tip fuel will be pumped overboard. Conclusion: Unnecessarily complicated. 5. Straight feed between tips and mains. No check valve. Advantages: Completely outweighed by disadvanteges. Disadvantages: No way to control fuel from feeding back into the tips while parked or in flight. If it occurs in flight it could result in fuel exhaustion. It could also result in an irretrievable spin if aerobatics attempted. Conclusion: Not practical as far as I can see. 6. Tips to mains through fuel selector. Calls for routing the tips fuel into the cabin to auxiliary selector(s) and then to the mains. Advantages: Virtually guaranteed fuel supply if correct selection made. Disadvantages: Additional fuel plumbing in wing and cabin. Additional fuel selectors which may present problems in terms of location, access and accidental movement of selector by pilot or passenger. Conclusion: Messy plumbing in cabin and fuel selectors everywhere. 7. One way electric solenoid. Fitted between tips and mains. Advantages: Complete control of fuel flow. Fuel can be retained in tips until mains reduced to avoid any possibility of fuel overflowing from mains vent or leaking fuel cap. Positive valve action will prevent fuel seeping back into the tips while plane parked. Disadvantages: Requires electric power to enable access to aux fuel. Relatively slow fuel transfer (but should exceed fuel flow required for 100% engine power). Conclusion: Not perfect, but might be best of the bunch. Have others had success with an electric solenoid. If so, what type of solenoid did you use. If you've had problems with this arrangement I'd like to know about that as well. careerone.com.au ________________________________________________________________________________

Subject: Re: Tip tanks (more)
Date: Mar 28, 2006
Bob, Per your item #5 below, (Straight feed between tips and mains. No check valve.) flow to the tip tanks can be some what mitigated by the position of the inlet to the main tank (from the tip tank). Jon's plans call for this fitting to be in the center of the tank height. This results in there always being fuel in the main tank, and the inability to drain to the tip tank once the main tank level goes below the level of this fitting. This is something like 10 gals of fuel. It also takes a fair amount of time for the tip tanks to refill, and the aircraft must be in an abnormal position (wing low on a ramp, or a continuous slip) for that time period to have a substantial amount of fuel drain out of the main. In flight, if the low wing were selected, you would also run the risk of un-porting the fuel pickup before a substantial amount of fuel were moved (but this is another problem). What I like about this setup is that there in no pilot input required to utilize the tip tank fuel: no fuel selector to forget to position, no electric pump or solenoid to forget to shutoff.. If there is fuel in the tip tank, then the main tank is always full. I'm in the process of trying this setup out. I'll post to the list the results of my tests. I should have it completed for the trip to Sun 'N Fun next week (4/6 - 4/7 for me...). From: "Bob Barrow" < bobbarrow10(at)hotmail.com > Subject: Tip tanks (more) > I also plan on using tip tanks on my RV7A. And I've also been pondering this fuel feed question for at least 12 months. This is a very good thread and timely for me. I've seen many solutions (actually flying) for feeding fuel from the tips and I've listed a few below with a few of my comments on each. Just my opinion of course and I welcome further feedback. 1. Floating "cistern" style valve in main tank. Opens valve to allow fuel to flow from tip to main when fuel in main gets down to a certain level. Advantages: Fully automatic..nothing to do or remember. No chance of fuel being vented from mains vent. Disadvantages: No suitable valve available on the market as far as I know which means you have to manufacture it. May be prone to mechanical failure. A nightmare to get to if it fails. Conclusion: Not for me. 2. Five way fuel selector. Andair sells them. Enables selection of either mains or either tips individually. Advantages: 100% access to auxiliary fuel guaranteed. No check valves to fail. No problems with differential vent pressures between mains and tips. Disadvantages: You'll have to run the tips dry to empty them which means the engine will stop. If you're not careful and you leave the tips selected you might lose engine power at a bad time. Conclusion: A potentially dangerous set-up if you get distracted. Using all useable fuel in flight essentially means running a tank dry. Not for me. 3. One way mechanical valve. Andair sells them and they are fitted between the tips and the mains. Advantages: Very reliable in terms of fuel availability and nothing to remember. Disadvantages: Can result in fuel overflowing through mains vent if pressure differential not precise. Once flow starts it may be assisted by siphon effect. When the plane is parked with full mains, fuel will seep back through the one-way valve and refill the tips. This can be a problem for accurate fuel measurement. It also precludes any aerobatics until the fuel can be pumped back into the mains in flight. Also requires a well sealing fuel cap to prevent fuel loss at the cap (that excludes Vans caps which are terrible). Conclusion: Popular solution but not without problems. 4. Electric fuel pump between tips and mains. Advantages: Fast fuel transfer. Control of flow. Disadvantages: Requires electric power to gain access to aux fuel. The pump introduces another failure point. If the mains are full when the pump is switched on then all the tip fuel will be pumped overboard. Conclusion: Unnecessarily complicated. 5. Straight feed between tips and mains. No check valve. Advantages: Completely outweighed by disadvantages. Disadvantages: No way to control fuel from feeding back into the tips while parked or in flight. If it occurs in flight it could result in fuel exhaustion. It could also result in an irretrievable spin if aerobatics attempted. Conclusion: Not practical as far as I can see. 6. Tips to mains through fuel selector. Calls for routing the tips fuel into the cabin to auxiliary selector(s) and then to the mains. Advantages: Virtually guaranteed fuel supply if correct selection made. Disadvantages: Additional fuel plumbing in wing and cabin. Additional fuel selectors which may present problems in terms of location, access and accidental movement of selector by pilot or passenger. Conclusion: Messy plumbing in cabin and fuel selectors everywhere. 7. One way electric solenoid. Fitted between tips and mains. Advantages: Complete control of fuel flow. Fuel can be retained in tips until mains reduced to avoid any possibility of fuel overflowing from mains vent or leaking fuel cap. Positive valve action will prevent fuel seeping back into the tips while plane parked. Disadvantages: Requires electric power to enable access to aux fuel. Relatively slow fuel transfer (but should exceed fuel flow required for 100% engine power). Conclusion: Not perfect, but might be best of the bunch. Have others had success with an electric solenoid. If so, what type of solenoid did you use. If you've had problems with this arrangement I'd like to know about that as well. careerone.com.au ________________________________________________________________________________

Unless you're real careful, the last place you want to buy an engine is at a salvage yard. Last time I talked with my insurance contacts the insurance carriers that he knew of, were requiring the total destruction on the aircraft that were totaled because of water emersion and lack to treatment after they were pulled from the flood. The salvage yard had to crush them with a bulldozer and certify that all parts would never be in the stream of commerce again. What a waste.

Hi Fred, thanks for your comments. I actually received quite a lot of replies to my post but for some reason people chose to email me directly. I appreciated all of the comments but I would ask people to respond through this forum because it enables everyone to gain benefit from the diversity of opinion and experience. In terms of your specific direction re straight feed. There are a number of reasons I feel reluctant to go that way but I will raise just one. The ability of the RV to recover from a spin depends primarily on the capacity of the rudders' authority to overcome the moment of the spinning wings. And because moment is lever arm multiplied by mass it therefore stand to reason that even a small increase in mass at the wing tips will grossly increase the moment. For a start all tip tanks will add at least 6 lbs over the weight of standard tips (dry weight). That alone may influence spin recovery. Any additional mass in the form of fuel in the tips (extra 1kg per litre approx) could prove fatal in a spin....even a very small quantity (say just 3 or 4 litres) may lead to an unrecoverable spin. On the other hand it may not...it might take 10 litres...but I for one will not be the test pilot finding out where the limit is. So I would say that it would be very prudent not to get into a spin with any fuel whatsoever in the tips. And the straight feed solution can never guarantee that the tips are completely empty. So aerobatics would be out of the question...firstly because they would guarantee that fuel would run to the tips...and secondly because it greatly increases the chances of an inadvertent spin. As Einstein was reported to have said: " A mechanism should be as simple as practicable...but no simpler" (or words to that effect). In aviation oversimplification can introduce risk...just look at Van's nose gear. >From: "Stucklen, Frederic W UTPWR" <Fred.Stucklen(at)UTCPower.com> >Reply-To: rv-list(at)matronics.com >To: "'Bob Barrow'" >CC: "'RV-List'" >Subject: Re: RV-List: Tip tanks (more) >Date: Tue, 28 Mar 2006 09:57:00 -0500 > > > >Bob, > > Per your item #5 below, (Straight feed between tips and mains. >No check valve.) flow to the tip tanks can be some what >mitigated by the position of the inlet to the main tank (from the tip >tank).

Yep, crushed by a hangar door, rolled over by winds. The problem is that by the time the savlage yard gets it the engine has been seperated from the airframe and you have to take the yards word for the source of the engine. You're better off bidding on the salvage directly with the insurance companies.

Subject: Re: Looking for an engine
I definitely echo the sentiment of caveat emptor, but there are some reputable, at least in my experience, salvage yards out there. I purchased a hurricane-damaged engine from Wentworth Aircraft last September for my RV-7A with the intention of overauling it. They guaranteed all of the expensive parts (crank, case, etc) to be within serviceable condition. I believe this is true for all of the engines they sell unless they specifically say that a part is bad. Anyway, after dissassembling it and taking it to a machine shop, the crank was found not to be within serviceable limits and the case had a seriously worn down main thrust face - nothing that could be found without dissassembling the engine. After not being able to find a replacement crankshaft, Wentworth refunded my money, and even covered the cost of teardown and inspection - something they were not liable for as their contract states that only the cost of the engine will be refunded in this case. While not being happy about having to find another engine, I was very happy with the way Wentworth handled the situation and would not hesitate to deal with them again on my next project. So I guess the moral of the story is if you are going to buy a salvage engine, get a guarantee or warranty on the major parts, and if you are worried about the source of the engine, ask the salvage yard for the N-number of the aircraft that the engine came off of and contact the owner. I was able to contact the owner who verified the information provided by Wentworth. If they won't give or don't have the N-number, move on. Scott Farner - former IO-360-A3B6D owner, current IO-390 owner (well in a week or so) www.scottfarner.com RV-7A Wiring Oh yes, and for completeness, I have no affiliation with Wentworth, just satisfied with the way they do business.

I have Jon Johanson's tip tanks and have been following this discussion with great interest. The change in the spin characteristics, even when empty, does concern me, as does the fuel venting problems already discussed. I haven't installed the tip tanks yet, and I still have the wingtips that came with the kit so I still have options. I would NOT consider Jon's tanks as "removable", although I'm sure some of you could remove and replace them with regular wingtips, including the plumbing and wiring in a few hours if you wanted. It would take me more like a week. It would be helpful to me and others if you would let all of this discussion go to the archives. Thanks for all the great information, guys.

Yes I am. At least an incipient spin...maybe even up to 2 turns. I don't see that's it's practical to remove the tip tanks. The answer is to keep them as light as absolutely possible. I know for a fact that some home-built tip tanks end up weighing a ton...many builders don't even know what their tip tanks weigh....they just keep slopping on the resin. Standard Vans tips (one tip) are approximately 6.5 lb. Johanson tip tanks vary but generally weigh between 11.0 and 12.5 lb (and they have no baffles inside). I certainly wouldn't want any fuel in the tips though...not a drop. >Are you planning to test spin recovery with the tip tanks installed, >but empty, during your test phase?

Subject: N4032Q
Date: Mar 29, 2006
I completed the first flight in N4032Q, an RV8A, yesterday at HEF, Manassas Regional Airport. All went well except for a few glitches. I'll bet not many of you have had to file an IFR flight plan for your first flights. Since HEF is within the Washington DC ADIZ, I did. Controllers were, however, as helpful as regulations would allow. I was able to remain in contact with the control tower but still orbit the airport at 2,000 to 2,500 feet. It was somewhat stressful to avoid going above 2,500 and into Dulles Airport's class B airspace but it was nice to hear the tower advising arriving traffic I was there in case they were thinking it was unimportant to get down to pattern altitude. It was comforting to see HEF's long runways right below me. To stay within 2 miles, I found I had to bank more steeply than my first flight test plan allowed as I was breaking in a new engine and had decided to run at 2,500 rpm and 25 inches. On takeoff, a strong left yaw and left roll defeated my intention to note my liftoff airspeed. After landing I was astonished to see that I had rotated the right main gear leg fairing well out of position even though I had marked the correct position when I aligned them initially. The round gear legs of the 8A made this possible & I would caution 8A builders to make this part of their final check since it can require an uncomfortable amount of correction while flying. I added a device for holding 25lb free weights to the aft baggage compartment shelf per Gus Funnell's advice to make the initial flight with the CG in the center of the allowable range. This proved to make control pressures feel a lot like the 6A factory demonstrator I flew with Mike Seager to prepare for my first flight. Problems setting all the control parameters of my Grand Rapids EIS 4000 engine monitor caused a spate of false warnings which made it difficult to know my power setting.

Congrats - I'm on the opposite side of the Chesapeake from you (N06) just starting my firewall foreward. If your flyoff area permits - stop on by....or we'll hope to see you after your fly-off period.....

All went well except for a few glitches. I'll bet not many of you have had to file an IFR flight plan for your first flights. Since HEF is within the Washington DC ADIZ, I did. Controllers were, however, as helpful as regulations would allow. I was able to remain in contact with the control tower but still orbit the airport at 2,000 to 2,500 feet. It was somewhat stressful to avoid going above 2,500 and into Dulles Airport's class B airspace but it was nice to hear the tower advising arriving traffic I was there in case they were thinking it was unimportant to get down to pattern altitude. It was comforting to see HEF's long runways right below me. To stay within 2 miles, I found I had to bank more steeply than my first flight test plan allowed as I was breaking in a new engine and had decided to run at 2,500 rpm and 25 inches. > >On takeoff, a strong left yaw and left roll defeated my intention to note my liftoff airspeed.

My experiences with Wentworth have been similar. I bought a yellow tagged 3 inch FD (ADI) from them. Sent it to the manufacturer for inspection and was told it was junk. I had a tough time but was successful in getting my money back. I was still out shipping and inspection fees. Not a good experience.

I purchased a hurricane-damaged engine from Wentworth Aircraft last September for my RV-7A with the intention of overauling it. They guaranteed all of the expensive parts (crank, case, etc) to be within serviceable condition. I believe this is true for all of the engines they sell unless they specifically say that a part is bad. Anyway, after dissassembling it and taking it to a machine shop, the crank was found not to be within serviceable limits and the case had a seriously worn down main thrust face - nothing that could be found without dissassembling the engine. After not being able to find a replacement crankshaft, Wentworth refunded my money, and even covered the cost of teardown and inspection - something they were not liable for as their contract states that only the cost of the engine will be refunded in this case. While not being happy about having to find another engine, I was very happy with the way Wentworth handled the situation and would not hesitate to deal with them again on my next project. So I guess the moral of the story is if you are going to buy a salvage engine, get a guarantee or warranty on the major parts, and if you are worried about the source of the engine, ask the salvage yard for the N-number of the aircraft that the engine came off of and contact the owner. I was able to contact the owner who verified the information provided by Wentworth. If they won't give or don't have the N-number, move on.

Subject: Re: Tip tanks (more)
Date: Mar 29, 2006
First off, Jon explicitly states no aerobatics in his instructions. He also states that the plane must be placarded against spins if there is ANY fuel in the tip tanks. That's enough to convince me to adhere to those instructions. I've intentionally spun my RV during the test period (without tip tanks) and agree with Van's observations that the RV6 (with the old vertical stab & rudder) does not recover well (once established - might take 6 turns - it took over three turns to recover...). Adding ANY weight to the wing tip area will only make that recovery worst. I agree that this includes the additional weight of an empty tip tank. That said, it doesn't mean that adding the weight of extra fuel to the wing tips for NORMAL flight condition, is dangerous. The issue is the KNOW what the operational limitations are under those condition, and to stay away from those limits. I'm satisfied that the operational characteristics and limitations of the RV6 with wing tanks is safe. And I don't plan on spinning the aircraft intentionally. And knowing the limitations, I plan on staying away from conditions that might induce a spin.... The original issue of these posts was to get information about any venting issues from those flying their aircraft. To date, I've only got feedback from one individual whose flying aircraft experience a problem with draining the tip tanks while in flight. He was able to modify the main tank vent slightly (from a 45* angle into the airflow to a 30* angle) and demonstrate proper operation. There has been no other flying aircraft (with tip tanks) feedback... So far, I'm the only flying aircraft (on the list) that has had the opposite problem - venting fuel out the main tank vents because of excessive tip tank vent pressure relative to the main tank vent pressure. I'm not comfortable with the dual vent design. I'm planning on modifying that design (one side at a time) this weekend to a single tip tank vent for both tanks. This will require the removal of the check valve (& replacing it with a union) and capping off the existing main tank vent. From an operational point, this approach will always require the operator to fill the main tank prior to adding any fuel to the tip tanks. I'll keep the list informed of my progress and test results.... Fred Stucklen RV-6A N926RV bobbarrow10(at)hotmail.com> Hi Fred, thanks for your comments. I actually received quite a lot of replies to my post but for some reason people chose to email me directly. I appreciated all of the comments but I would ask people to respond through this forum because it enables everyone to gain benefit from the diversity of opinion and experience. In terms of your specific direction re straight feed. There are a number of reasons I feel reluctant to go that way but I will raise just one. The ability of the RV to recover from a spin depends primarily on the capacity of the rudders' authority to overcome the moment of the spinning wings. And because moment is lever arm multiplied by mass it therefore stand to reason that even a small increase in mass at the wing tips will grossly increase the moment. For a start all tip tanks will add at least 6 lbs over the weight of standard tips (dry weight). That alone may influence spin recovery. Any additional mass in the form of fuel in the tips (extra 1kg per litre approx) could prove fatal in a spin....even a very small quantity (say just 3 or 4 litres) may lead to an unrecoverable spin. On the other hand it may not...it might take 10 litres...but I for one will not be the test pilot finding out where the limit is. So I would say that it would be very prudent not to get into a spin with any fuel whatsoever in the tips. And the straight feed solution can never guarantee that the tips are completely empty. So aerobatics would be out of the question...firstly because they would guarantee that fuel would run to the tips...and secondly because it greatly increases the chances of an
