This is a Maclan Racing MRR V2m 7.0-Turn Sensored Brushless Modified Class Competition Motor. The MRR V2m modified class motors are based on the successful MRR Team Edition V2 stock class platform. With a completely redesigned stator and windings, updated end cap, and 12.20mm ultra smooth rotor, the V2m provides much smoother low to mid-range power band. It also reduces weight by an average of 12% over its predecessor. Optional 12.50mm rotors for high torque and ultra-high torque are also available for different track conditions and sizes.
