This gearbox has been especially designed for use with the most popular motors having either 8mm or 10mm fixing hole centres. Provision is made for an ‘outrigger’ motor shaft bearing (not supplied) for motors such as the DS10. Like all Comet gearboxes, it is designed to fit a standard 1/8″ driving axle (not included).
The photo shows the gearbox fitted with a Mashima motor and a Comet flywheel. Spare gears are GEAR38R, GEAR50L and WORM15.
