Servo specs and so on.

what would a servo's minimal oz of torque be to turn a ruckus.

I am looking for a good servo that will last a long time.
6v
Metal gear
Speed less than.17/60°

Minimal torque? The stock servo is fairly weak but it has what I would regard as "minimum torque to steer." Based on the labels of "high torque" I've seen on various brands of servos, I'd say that somewhere around 180-200 oz/in (12-14 kg/cm). A little more is better, but much over 250 oz/in torque in a 1/10 scale truck and you'll start seeing rapidly diminishing returns on your money spent, plus you'll need an ESC that will output 7.4V to the Rx.

This US$40.00 Savox servo would be a pretty good upgrade over stock: http://www.savoxusa.com/Savox_SC0251MG_Digital_Servo_p/savsc0251mg.htm
