Chuck,Got your video the other day and really enjoyed it. Thanks for all the effortthat went into making a good documentary. I thought tailwheel shots from belowwere really cool.Quick question: what prop do you have on the A-65? I ask because I'm pulling 2200rpm on takeoff and climbout with a 72 x 42 Hegy. From the video it lookedlike you weren't getting the same rpm's out of the same engine/airplane combination,although cruise looked to be about the same.Dave MordecaiPanacea, FLkmordecai001(at)comcast.netChuck,Got your video the other day and really enjoyed it.

It's a 72 X 42, Birch wood, Kevlar leading edge, Fiberglass covered. Speaking of props...a few days ago, I pulled my prop off to do a little bit of re-work on it. About 5 or 6 weeks ago, I got hung up on the edge of a gravel taxi road, and I had to use a LOT of power to get 'er rolling again. Well,it sucked up some gravel through the prop, and put some little marks on the leading edge. I'm going to take care of that, as well as work the trailing edgedown a little bit, and thin it down just a tiny bit, to get a few more rpm's. My tach (reads a little low), and ASI (also reads a little low) both have errors in them, but to the best of my estimation, I'm getting 2250 rpm at fullpower, level flight, and something close to 80 mph. The engine is rated at 2300rpm, so I'm right in the ball park now, but I would like to get it a little closer to 2300 rpm at full power level flight.Chuck G.________________________________________________________________________________
