uhuh thats rite, the torque of a servo and the ability of the spring to return the servo is unrelated. I guess decent servos are ballraced have stronger faster motors so low gearing it isnt as necessary to produce decent torque so your end result is a servo that is much easier to rotate at the horn end.
