There is no airshow or formal waivered airspace. But there will be room to fly and an appreciative audience. The tower understands the needs of formation and is very accommodating. If you can bring a group of RVs, Rockets, or mixed formation, great. We'd love to see you and fly with you. I'll be in the little blue Lancair. -bob mackey ________________________________ Message 2 _____________________________________ Time: 03:59:21 AM PST US From: "Kyle Boatright" Subject: Re: RV-List: some approx V speeds Thomas, which engine and prop do you have? Whether you have fixed pitch or constant speed prop makes a difference. ----- Original Message ----- From: thomas sargent To: rv-list Sent: Thursday, June 03, 2010 1:37 AM Subject: RV-List: some approx V speeds Anticpating the first flight of my RV-6A, can some one tell me typical Vx and Vy, best angle of glide speed, and Va for these planes. I can refine them after it is flying, but I'd like to have some idea of what to expect to start with. -- Tom Sargent ________________________________ Message 3 _____________________________________ Time: 06:01:52 AM PST US From: "emrath" Subject: RV-List: Radio Noise Jim, I have a newly minted RV-6A with a similar set up, about 10 hours on it now. I had to adjust my Side Tone on the SL-30 because of feedback thru the mike. The procedure should be in your manual. I turned the side tone down and it's now much better. Strange, I'm using DC 13X headset but the new DC 11X I purchased for my co-pilot doesn't have the same problem. Also, the transmit noise seems to be worse with the ANR turned off. Hope this helps.

Horrible static sounds like fairly high current arcing is taking place in the air. Pull all the accessories off-line (switches, fuses, ckt breakers open) and try transmissions with only the radios powered. Turn off the alternator. You may even have to turn off the mags and glide for a transmission or two. Don't have any experience with P or E-mags so don't know if they need or have P-lead filters. Let us know what the testing does.

I woul d suggest you turn down the Mic Gain in the radio. For my first flights, it was painful to key the mic as the noise in my ears was like a sledgehammer. The cockpit of the RV's is a really noisy place and that noise gets into the mic and gets amplified. On the Icom, there is a foil sticky on the top surface of the radio. Peel that back and there is a var iable resistor inside. Note where it is, then turn it down some. I think in my case it was origi nally about half way and I turned it down to about 1/4 and took a flight to check. After about three flights, you'll zero in on where you want it. I hope this is the cause of your problem be cause it is an easy fix.

Set up is: RV-7A with an SL-30, Bob Archer antenna in left wingtip, with PTT on stick also FWIW I have a P-Mag and E-mag. Radio is excellent on ground in both transmit and receive, reception in air is OK however when I press the PTT the noise is horrible with static and breaking up. This has been a consistent condition. Attempts to correct the problem have been: checking antenna installation in wingtip, everything seems fine, Checking connectors where stick PTT plugs into the system, the PTT pin may not have been fully seated, it is now, trying different headsets. Nothing has solved the problem to date. I have been working with the tower on this flying the same circuit and when I contact them it is always somewhere between almost NORDO to just generally poor communications. When I'm back on the ground everything is just fine again. Ideas, directions or suggestions?

These are nice PVC inflatables with comfortable seating, headrest, mesh bottom, quick-inflate valves, drink holders, and rave reviews from other users. We tried 'em out Memorial Day and can confirm they are far nicer and more comfortable than black rubber tubes with slow leaks (as most of our old tubes quickly develop). While not essential (we still have quite a few of the old tubes on hand and can patch them), we are recommending that guests wanting to have the best tubing experience this year order tubes like we did from Amazon or another vendor. We paid 13.88 for the tubes with free shipping and I see they have already gone up a bit as river season arrived. Might want to order NOW ;-) http://www.amazon.com/Intex-58825-River-Run-I/dp/B000PEOMC8 -Bill B On Tue, Jun 1, 2010 at 10:41 AM, Bill Boyd wrote: > Hi, folks!
