    Chuck, Mine is actually an A-75, but I think the horsepower curve is the same as the A-65, just extends farther out to 2600 rpm, although it can't rev that high with this prop. It really gets off the ground well pulling 2150-2200 rpm and tops out at 2400 & about 85 mph indicated. Haven't checked it with GPS yet, but who flies that fast anyway?

Chuck, Mine is actually an A-75, but Ithink the horsepower curve is the same as the A-65, just extends farther out to 2600 rpm, although it can't rev that high with this prop. It really gets off the ground wellpulling 2150-2200 rpm and tops out at 2400 about 85 mph indicated. Haven't checked it with GPS yet, but who flies that fast anyway? I like 65 or so................ Dave <mailto:nharris25@yahoo.com> Dave, I'm glad you enjoyed the video !! I built my prop. 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 edge down 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 full power, level flight, and something close to 80 mph. The engine is rated at 2300 rpm, 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. </mailto:nharris25@yahoo.com>

A lot of times I'll pull power back to about 1800 rpm, just over 50 mph, sip less than 3 gallons an hour, and just absorb the scenery !! Chuck G.
