FWIW I have an Andair valve and discovered at about 15 hours that it was leaking very slightly at the square plate on the front of the valve into which the AN fitting to the right tank threads. I disassembled the fuel valve console, removed the valve, tightened the four screws that secure the square plate and staked them (only the Brits do this kind of thing). Eighteen hours later I don't have any more leaks, but have my fingers crossed. As far as the engine hiccups are concerned, now that I think back I may have had a few early on but would hesitate to blame them on the seeping fuel valve.

(not processed: me... --> RV-List message posted by: "Helming, L R & K L" I will add some to the Mark's response. Before scuffing with scotchbrite, clean with naptha (aka coleman lantern fuel) using clean cloth and wash the surface well with a good soap such as Dawn dishwashing soap. This gets rid of any oil, finger prints, etc. I like to use the soap also while scotchbriting it. Then wear rubber gloves and rinse well and do not allow your skin to touch the surface before priming.

(One aircraft without modifications between propeller tests. True ias used to compensate for differences in pressure and temperature.) Each reading was made to the nearest mph ias. The repeatability of this reading alone is only within 1 mph. Even though we were flying in smooth air up to 80 miles out to sea, we were over some islands, and were getting occasional up and down drafts (standing waves). My best guess is each data point is accurate within 4 mph ias. For the 30 plus data points taken for each propeller, there doesn't appear to be any significant difference in the performance of these cruise CS propellers. Some trends can be observed. The Hartzell appears to have a slight performance edge at 2,500'. The MT 3 blade seems to have a light performance edge at 7,500' and above. (Both of these 2 blade vs 3 blade trends are correct for CURRENT propeller theory.) Each flight involved 5 different altitudes with 5 to 10 power settings at each altitude. My friend with the RV-6A seemed to loose interest in this type of flying after 7 flights. :-) Regards, Jim Ayers In a message dated 02/27/2005 11:59:35 PM Pacific Standard Time, rv-list-digest@matronics.com writes: Time: 05:28:02 AM PST US From: Kevin Horton Subject: Re: RV-List: cruise performance test data listed --> RV-List message posted by: Kevin Horton (Stuff cut) Is your data repeatable over several flights?

I wouldn't recommend trying to "file out" the cracks. Unless you've got a dye penetrant kit handy, you probably can't see the end of the crack, so you don't know how far to file.

It is MUCH less than a cylinder missfire. I believe it is a random misfire of one of the two plugs due to the mixture not being perfect at that plug, happening about one time per thousand firings. That will produce a very slight reduction in power from that cylinder, that cycle. This was totally predictible when cruising with very lean mixture. No harm done! Paul S.

I know, "now ya tell me!" Make a part from the male mold and then get it smooth as a baby's butt ..... just like you want the end product to look like ....

Epoxy will be stiffer, but more expensive, than polyester resin.

The last version of the software seems to be very stable and I am having no issues with the Dynon. They had some struggles early and the thing that came thru loud and clear on this list was the great service they provided.

I have noticed that the Altimeter setting may vary from 20~70' from actual even after warm up. Not sure if this is normal. And the TAS just went wild on the last two flights which might be a bad temp probe. They have been good to work with. Enroute I always look at the Dynon for airspeed and Alt however I always refer to the old airspeed ind and altimeter on landing for some reason. I have actually covered up the old gauges with sticky notes in an effort to re-train me. I recommend it.

By building my RV9A at home, I did not have to leave the family to go to the airport. I could work on it after work, after dinner. My wife and kids could still talk to me, I could have dinner, say good-night to the kids etc. When I finally moved the finished parts to the hangar, it took FOREVER to get things done. All the guys in the hangar area would stop to chat and check progreess. It got to a point that I would hide my car around the corner, keep the door closed and keep the radio quiet just so I could be left alone to get something done. Don't get me wrong - I enjoy a good visit and I love to talk airplanes, but my time off is rare and building time away from home is sacrad. All the guys at the airport are great - but I am glad that I did most of the construction at home. ... just one guys experiences....

I got to thinking about your harnesses. I like working with electrical stuff and would enjoy making my own harnesses but....I've been working on this airplane for many years now and it is so close to flying I can taste it. If I had someone make my radio harnesses while I was working on these last little airframe details and installing the motor, it would fly that much quicker. So......I have a full UPS AT radio stack (SL-70 transponder, SL-30 Nav/Com, GX-65 GPS/COM and the SL-15 audio panel). I also have the Dynon D-10 (no serial I/F) and the Mid Continent Instruments 3 1/2 inch VOR/ILS indicator. I want to use the Dynon to provide altitude to the SL-70 and want the GX-65 to be able to talk to the SL-30 (RS-232 serial bus I think). I think that the SL-15 has intercom built in and it's stereo so I'd want stereo headset capability in that harness, plus, I'd like to be able to plug in a portable cassette, CD or MP3 player into the audio system AND, be able to record ATC transmissions out of the audio system (a couple extra jacks for input and output that I could install in the glove box or under the panel). And, last but not least...a harness to come out of an Ez Pilot wing leveler control head long enough to reach my Navaid Servo installed in the right wingtip (EZ Pilot connector on one end and NAVAID servo connector on the other). Can you give me a rough idea how much harnesses to do all this stuff would cost if I bought them from you? What would you need from me to make up the harnesses? Mounting trays, pins, schematics, what?????? Thanks. Dean Psiropoulos RV-6A N197DM Tarpon Sprgs, FL
