Freewheel?

To prevent motor stripping slowly bring down the rpm.

its basically a brake making sure that the drive wheels do not drive the engine/motor and remove the chance of the motor seizing or breaking

I've used both vex and IFI motors.. somehow I wonder why they do not put in metal gears. The modded-servos with metal gears are pretty strong, and coupled with the clutches would nearly remove any possibility of gears stripping. bringing down rpm also reduces this possibility a LOT. Like for e.g., do not drive ur bot into a sudden reverse when going down a ramp
