Replace fragile plastic internals on the Thunder Tiger Kaiser XS with this GPM steel spur gear set. The package contains a 56T spur plus a two piece double speed reduction gear train, manufactured in steel #45 to resist wear and extend runtime between rebuilds.
Power is routed into the 56T spur then stepped through the 12T small gear and 33T large gear in the reduction block, producing greater torque at the centre drive shaft while easing strain on the motor at low speeds.
