What are the % efficiency gains by using a CR motor?

Comment by Edward Strickland on July 16, 2012 at 12:44pm: Theory says between 9% and as high as 15%. Depends if rear pitch is set higher than front prop. 2 and a bit x thrust and double the speed. No torque or gyroscopic precession. Ran these at high revs and no vibration. Eddie
