I used 9650's on a PL Lazulite with a Mintor 170 setup (shook like hell). They seemed fine at first, but the plane never really locked on (Thanks Tony F for helping me trim that plane). I then went to control horns that from the lower surface of the ailerons, stood off 1.25". This extra leverage made a huge difference in the way the plane flew. Then swapped in 9150s which are around 80 oz of torque - again - big improvement. Then, swapped in 9151, around 130 oz of torque, and have run them now for 3 years in various planes.

The electric setup being vibration free should help that servo a lot on the ailerons, but I would hessitate to think that 65 oz is enough torque (not enough for FAI). My personal feeling is that you should never skimp for weight savings on the stuff that matters to the feel of the plane (like servos) - if you are going to the nats and you MUST save weight - maybe - but not for any other reasons. Love the 9650s and use them on dual elevator setups or throttle, or smaller planes, just not on 2M plane ailerons. IMHO
