Mugen MTX-4R updated Gearbox parts
Mugen Seiki have announced the release of these new gearbox parts for the MTX-4R 1/10th scale chassis. Sold separately, but designed to be used together, the only difference is the use of 4mm balls for the gearbox mechanism, in place of 3mm versions used originally. This makes for a more stable shift between gears and to accommodate these new balls the gearbox shoes have been modified and are therefore new.
