RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Brenner I wish we could import some of your weather!
It was typically 13 - 14 C and mega windy blowing out 90 degrees for most of the weekend. While some of the Contras were running 22 x 20 front and rear others stuck with the 22 x 20, 22 x 18 mixed set and coped fine with 20 mph+ winds. It just goes to show that with the Contra you can pick your flying style and it will deliver.
