Minimum servo torque for IMAC flying?
I am finishing up a CA Models 27% Extra (no more than 15lbs. AUW) I plan to use strictly for learning IMAC and not 3D. I don't want to put a ton of money into servos because I view this plane as a learning tool, so what's the minimum servo torque I can get away with?
Ailerons: one servo per wing
Elevator: two servos per side in tail
Rudder: pull pull, one servo
Thanks.
