Trinity F45 brushless Race Motors deliver the muscle you need to make your 1/8 scale buggy or truggy perform like a champion. With 2S-6S LiPo power compatibility, these motors produce high rpm with exceptional efficiency. These power units also offer smooth acceleration and predictable low-speed drivability due to their sensored design. F45 brushless Race Motors offer a completely enclosed design, reducing your maintenance needs and giving them protection and durability to excel in demanding off-road environments. Other features include a 4-pole rotor for high torque, CNC-machined aluminum housing, insulated copper windings, steel 5mm output shaft, and smooth precision bearings.
