The Tamiya 84041 - TRF801XT lightweight universal shaft set is a precision upgrade for the TRF801XT chassis aimed at trimming rotating mass. Reducing the propeller shaft diameter from 4.2mm to 3.4mm lowers each shaft from 35g to 29.5g, giving a combined saving of 22g when all four are fitted and helping the car respond faster on throttle changes.
RC tuners who want sharper acceleration and tidier rotation will find these shafts useful. The lighter components reduce inertia at the wheels, which can improve acceleration feel and make the chassis easier to place through corners when combined with appropriate suspension and gearing choices.
