There isn't any loss of power. This setup is currently in a 42% Ulimate, that has been put through everything possible. No flutter, no blow bye, a solid setup. It does knife edge loops all day long, and how ever many you want to do. If this was a loss of power setup. The rudder and everything else would be flatting out! Right! This plane and the other 2 Extra's on the website are also flown in IMAC. No problems. They fly very well, I have flown all of them through the Unlimited sequences and some of the old TOC and Masters Unknowns that I have.

When I get my Yaks together, I plan on running torque test against standard and direct drive setups. I'll post the findings.

Gary-- I wasn't fly the Yellow Extra there, I was flying the red one.
