constristor, speaking of servos on the Yak,
I originally had JR 4721 on the ailerons, running at 6volts they have around 130oz of torque. I swapped those servos out to hitec 5945 on 6volts they have around 170-180oz of torque, and boy it made my roll rate increase, and it flys more crisp now.

For the tail, I am using hitec 945, I think they have about 150oz of torque, and they seem to be doing fine. I can't imagine how people fly this plane with 60-80oz servos.

Glad to hear the Yak's going back together.
