RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hi Brenner,
Hard luck about dropping a round for not judging. Hard to believe that someone didn't give you a push to get in the chair.... Good luck in the finals anyway.
When you did the sound check was it with your carbon props or the APC specials? Even at 94dBA you still have the tolerance of the measuring device to add on top.
Cheers,
Jason.
