RE: which requires more servo torque...
I have calculated the necessary servo torque needed for my new .90 sized CA Model Epsilon using the recommended throws for 3D-flying at 60 mph.
The result are as follows:
Aileron: 35 deg deflection requires 28 oz.in. torque (one aileron)
Elevator: 40 deg deflection requires 42 oz.in. torque
Rudder: 45 deg. deflection requires 54 oz.in. torque
