By the time you fit the canopy, cut off the windshield, fit the skirts and lay up the windshield fairing, you will find that it will not travel as far forward as it does now. Others my have a different opinion but that's the mine worked out. I'd press on. There's lots of latitude in the final fitting.

My previous headsets, all 4 pairs, were upgraded with the ANR Headset upgrades from http://www.anr-headsets.com/ and also beyond that, a noise reducing kit similar to the Oregon Aero Hushkit. (I got the materials and did it myself) In addition I installed Gel earseals. So these are very nice, very quiet, and good quality headsets, and I would bet each pair cost me $300-350 by the time I got done with them. I have 2 pair for sale right now. One pair is the Pilot Avionics P-51C Pilot Cadet's for kids: http://www.pilot-avionics.com/html/html_root/juniorhead.htm The other is a Flightcom 5DX: http://www.flightcom.net/headsets/5dx-headset.php with the ANR it would actually be closer to the Classic ANR set though. http://www.flightcom.net/headsets/classic-anr-headset.php I was going to list them on ebay, but I thought I'd post them here first in case someone was interested. I'm going to Sun-N-Fun and depending on the dates you'd be there, I could bring them along. If you're interested, I can send photos and you can make an offer.

I took my wife up in a 152 while building the RV-6. She hated it. Now that we have the RV, she has flown to Oshkosh with me 4 times, no problem, and that's from the west coast over the rockies. It's the difference between a rickety, will it fall out of the sky feeling, and the solid strong feel of the RV. (Nothing against the 150, we all flew them at some point, right?) Dw RV-6 925hrs do not archive --> RV-List message posted by: Hopperdhh@aol.com For the first few flights in our C-150 I did look over and see some white knuckles. What a sport! She is my best flying buddy now. For probably the first 2 years whenever someone would ask her if she liked flying she would reply, "It's getting better." ________________________________ Message 5 _____________________________________ Time: 04:41:20 PM PST US From: WPAerial@aol.com Subject: Re: RV-List: Tip tanks --> RV-List message posted by: WPAerial@aol.com Just wonder why u want tip tanks?

The ability to take a typical ~3 hr trip & return without refueling could easily save me $30-$50. Anyone who uses auto fuel or bases their plane where they have their own avgas tank can save $1/gal or more for each gallon they don't have to buy 'on the road'. Charlie ________________________________ Message 7 _____________________________________ Time: 07:35:39 PM PST US From: "Howard Walrath" Subject: Re: RV-List: Tip tanks --> RV-List message posted by: "Howard Walrath" Jerry, I would have to agree with Charlie. My RV-6A was constructed using one additional bay in each wing for fuel, giving it 27 gallons per side or 54 gallons total. It also lets me make many round trip flights without refueling, and yet always land with IFR fuel reserves remaining. One of the benefits of living at Hidden Valley Airpark (5TX0) is our 100LL fuel co-op, where we pay just $.06 per gallon over the cost of the gasoline (and our 79 members use a lot of fuel each month). Typically, I've found that equates to about half the cost of purchasing it away from the airpark.

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? Thanks, --Mark Navratil Cedar Rapids, Iowa RV-8A N2D flying 15.8 hours....love the flying, hate the cleanup afterwards.... ________________________________ Message 9 _____________________________________ Time: 09:16:45 PM PST US Subject: RV-List: Nosewheel bearing question From: Mark E Navratil --> RV-List message posted by: Mark E Navratil 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...).

I ended up adding a washer on one side of spacer which allowed me to tighten the axel bolt properly without binding the wheel.
