Thanks guys. The plane I'll try it on is the used Aerotech Chimpmunk I picked up. 90"wings span and 72" length. The dry weight of the airframe is 11 lbs. Buildt like a brick &$% house. I brough it to the field yesterday and showed the old-timers and they thought it was a perfect match for the G45. The engine the manufacturer reccomends is the brison 3.2. Others put G62 and even the Sachs 4.2! I'm just looking for a flyer, not a 3D performer. JB, you know the sukoi is probably on my list next. I'd just like to use the G45 on something that would be fun. Do you know what RPM you get with the APC?
