20Kg servo with the linkage 40mm out from the centre has the same torque as a 10kg one with the linkage at 20mm
I am sure that you meant to say force, not torque! Servo torque is a fixed number regardless of where you connect the pushrod. A 20kgcm servo is always 20kgcm and a 10kgcm servo is always 10kgcm of torque. It's the force applied to the pushrod that varies with radius.

Yes you are correct, my point was mainly that the 10Kg one was applying the same push/force as the 20kg one
