What the minimum amount of torque needed for the steering servo of the M03 when powered by the stock silver can motors? Since we race spec, non-rebuildable motors, weight becomes of paramount importance. I know the Futaba 9602 will work fine but will the 9601 with less torque and nylon gears be okay? How about the 9650? I have both of these servos and they are lighter than the 9602 because of their nylon gears. Thanks.
