RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hi Brenner,
Hope you've had a Merry Christmas! I spent mine flying. Got about 6 flights on the Onas and another 8 or 10 on helicopters!
I'd like to see us turning around 5,000 to 5,500 RPM on whatever size prop that would end up being. If that was 20x20's I think the models would fly better. Right now on the 9.8 ratio and the 22x20's I would like just a tad more speed when it was fully opened up. The vertical power now is excellent, but having a little speed in reserve would be better. ANd I'm actually increasing my idle RPM as the downline braking can be too much.
I just think unless we try the higher prop RPM ratios with smaller props we'll never know if that's not better. But then again, I'm just a playtime engineer, not a real one!
