I've got 2 slightly more difficult questions for you.

1. Instead of 1 inch arms on each end 1:1 suppose you go with 1/2 inch arms on each side. Do you then increase the torque available in the 1:1 ration by 50%. Or, overall is it still the same as the oz/inch rating for the servo.

2. Doesn't the force the servo exherts lessen as it nears the end of its range due to the force vector no longer being 90 degrees to the pushrod.
