RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

As far as I am concerned guys, we have a great first set of props that I think Brenner will have for sale very shortly. They are a little heavier but that has little or nothing to do with the sound...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I don't see why this is so hard to believe. They just made the 20.5x10 or whatever it is for the four stokes and we all no where that is headed unfortunately. The Contra drive is something that...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Those are yours and Steve is going to send them with his drive this week. I think all were going to do is add a half inch to the front prop and they will be readily available through Brenner. Amp...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Well today was the day the new APC props arrived and they look great. I cannot believe how stiff they are even though they are much thinner then their standard props. They are also lighter then I...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
