21.5, 25.5 : ROAR Approval Pending
Team Power Products R4 series are very smooth motors for pan cars and Formula 1 on hard surfaces.
Nine months of work with three redesigns finally allows release of the new Team Power Products R4 PRO Series ROAR Spec Brushless & Sensored motors. This new family of motors produces more torque at lower temperatures than the previous R3.0 and R3.1 designs. Considerable engineering costs devoted to its development makes the R4 a premium line of motors for those who compete at the highest levels of the sport.
