Revolution Design Racing Products have introduced their all new Ultra motor weight 15g. Made for hassle-free chassis weight distribution changes the lightest in RDRP’s line of motor weights, the 15g variant is of an updated design with milled-out sections that allow for improved motor cooling compared to their previous design. It can be fasted to the motor using two countersunk screws and unused mounting positions on the motor’s front plate, making for much easier installation and maintenance as it stays attached to the motor even when it is taken out of the chassis. The weight helps to up the all-up weight or optimise the weight distribution of buggies, touring and pan cars and it is simply inserted between the motor and the motor plate. The weight is usable with most 540 and 550-size brushless motors.
