RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
A quick update. Team Ireland had a practice session yesterday and all the contras were going great. Everyone that saw them seemed to be very impressed. I think we are all using the 10.15 gears and mixed props at the moment. I'm going to try the two 22X20's and 9.89 gears over the coming weeks to try and get a "high wind" setup.
