Following Scotts lead in re-thinking the 'servo requirement' I have gone to smaller lower torque digitals.

My set up:
Genesis ARF AXI powered
Ail- 9650s @ 62.5 oz/in
Rudder - 9550 @ 83 oz/in
Elevator - 9550

For 3D or IMAC style flying I can understand the higher torque requirements... but I have used this last set up in my last two airplanes and it works pretty well. My orginal reason for using them was to cut down on the weight and by doing so I saved 2-3 ounces. It wasn't too long ago that we were using 50 oz/in servos as the standard and had no problems... and those were ANALOG! Digitals are a whole new ball game.
