Before I take this sucker apart I'd like to find some documentation about it. Can anyone point to a service manual or procedure description, or is this thing simple enough to just start pulling screws without it going "sproing!!!!" on me? Are overhaul kits available for it and where from? It is model #1109657. Thanks!

Thanks for you patience. Now I need to find my engine so I can order the rest of your system. I have a question regarding the data logging in your original email: What is needed to make this work and be able to get some form of meaningful output out of it? Right now I am thinking of the flight testing phase of things. It would be nice to concentrate on flying primarily and analyze the logged data after I am back on the ground.

Like your ELT, huh? I have flown from Oshkosh to the West Coast half a dozen times but only once without oxygen. I had the equipment but neglected to check the amount of gas still remaining. Dumb. That trip, in the Debonair, I looked for all the low ground so as to have as much altitude as possible in case something went wrong. Another trip was IFR in the rain and I had to stay pretty low due to ice fear. The Rockies are rough on landing gear in places. April huh? Mine were in summer. Last summer coming back to Paso Robles (halfway between LA and SF) there was heavy forest fire smoke in the Sierras. The country is high and so was the smoke but I topped it in the RV6a at 17,900 ft. (No IFR equipment yet). It is a shame to be able to fly high and safe and not have the oxygen. Another benefit is gas savings. Often, there are often powerful tail winds up high even over the flat country. Maybe buy an outfit with a partner? K. H. (Hal) Kempthorne RV6-a N7HK flying!

It's about 8" long or so in order to get into every where. It works fine but is easy to get a slightly tilted shop head (ask me how I know). The also sell a nice round flat bucking bar to use on the skin side that makes real nice flat rivets with no marks in the skin.

Mike Crowe RV8A Waiting on wings Part # : 4580 Extra long back riveting set $26.00 Some "RV" builders are back-riveting the wing & fuselage skins to obtain a smoother finish. This requires a long (10-1/2") rivet set, modified with a flat recess instead of a cupped recess; and with a slight (3 - 4 degree) single offset bend near the tip to aid in clearing rib flanges. (Works great with our #635 bucking bar). -----Original Message----- From: lucky macy [mailto:luckymacy@hotmail.com] Sent: Saturday, March 22, 2003 5:08 PM To: rv8list@yahoogroups.com; rv-list@matronics.com Subject: [rv8list] back riveting wing skins Is there an offset flat set for back riveting the top wing skins or can I take my AN470-4 offset rivet set and use it to make the shop heads on the AN426-3 rivets?

A fast taxi, tail down, will cause it sometimes too. I've got the stiffeners in the gear legs. I've recently switch to the Jantzi steering link, but it didn't seem to make any difference one way or the other. It doesn't do it every time, the tailwheel seems to do it more often than the main gear. Although, it may be just the tailwheel and may just feel like the main gear are going too. I'm thinking it's an alignment problem, but which way? The tailwheel pivot is not vertical, but slanted back slightly which may be the main culprit. How do you fix that? The tailwheel rod isn't bent. The main gear tires don't show any signs of abnormal wear. No problems on takeoff or wheel landings until the tailwheel is on the ground. Has anyone else run into this? Thanks, Dave RV-6 ________________________________ Message 8 _____________________________________ Time: 04:17:15 PM PST US From: John Bright Subject: Re: RV-List: back riveting wing skins --> RV-List message posted by: John Bright Tony Bingelis said it's OK to use an AN470-4 offset rivet set. I bucked them and used a flat swivel set with rubber boot... this worked great except the bucking bar rested on one cleco and the swivel set made a depression in the skin. On an RV-6 if you do the top skins first you can't put the wingwalk ribs in one at a time because the flap brace won't allow access to buck the rib to rear spar rivets. Some dexterity will allow you to buck the wingwalk rib to skin rivets with all the ribs in though... other than that it's blind rivets.

I also prepared the cowling hinges, and the required shims, and before I rivet them to the FW flange (which would be more difficult to do once the engine mount is permanently bolted on), I wanted to ask what you might think about this idea: You know how vibration in the engine compartment has been blamed for hinge-eyelets breaking off in this place. well, what do you think about "sandwiching", or spreading, some high-temp RTV between the hinges, the shims and the firewall flange before rivetting ? My thought is, that this thin layer of rubberized compound might act as a little "shock absorber", to dampen the vibrations before they get to the hinge. Am I making sense or is this going to cause more trouble than help ? Has anyone tried this before ? Any Tech counselors want to offer their opinion ? Thanks, Amit. ________________________________ Message 14 ____________________________________ Time: 07:47:22 PM PST US From: "Dan Checkoway" Subject: Re: RV-List: Hartzell 7692 vs. 7666 --> RV-List message posted by: "Dan Checkoway" Yeah, I have no intention of using the Q tips...but according to the latest TCDS (P-920 rev. 25), these are the blades that can be used with the IO-360-A1B6: F7068 (68"/66") F7666A-4Q (72") 7666 (76") F7666 (74"/72") F8477 (84"/78") Of those, the only "approved combination" using a 72" version with the -A1B6 is the Q prop...which is strange because Van's sells the F7666A-4 as a 72". I'm sure I'm just picking nits here, but oh well. I'd love to find out about the 7692 and 7694. I believe Van's listing of the "7496" prop in their catalog is a misprint...and should read 7694-2.

It helps to dampen out oscillations. If it's canted back, that's bad. It can chatter like a beat up Walmart shopping cart. Another possibility is the tailwheel bearings or condition of the rubber. My tailwheel wore one side more than the other. I swapped it around to even out the wear. It never caused any chatter or shimmy that I could discern, just looked odd. The main gear on the -6 is so totally different than on the -8 that I can't comment much on it. I have seen Whitman gear that wobbled like shell shocked Iraqi Republican Guard when a certain ground speed was attained, then smoothed out just as quickly. Others shimmy all the time. Probably the quickest and easiest test would be to swap the tailwheel around and see if anything changes. Beyond that, the main wheels could be switched, and/or air pressure changed a bit.

I've heard that Tailwinds can be very sensitive to tire pressure and wheel shimmy. Lower pressure is better.

The copy I have of the TCDS is rev. 24, July 30, 2002 Check out page 9, third prop down. The diameter range shown is 76" to 72", Van's -4 is a 72". The "A" is a minor mod that doesn't effect eligibility. The fastest RV guys thus far, have taken the Hartzell's and retwisted them (better twist distribution for the rpm and airspeed), turn them at higher rpm (up to 3000 rpm) and in some cases clipped them less than 72". It's going to be interesting to see Randy Lervold's test results with the Whirl Wind 200C vs. the 150 3 blade. MT has got some new interesting stuff too, I'll know more soon.
