ROAR APPROVAL: Approved for V21-S 17.5 , 13.5 & 21.5   

Our fastest ROAR approved V21, 17.5 ,13.5 and 21.5 motor is now upgradable. After over 2 years in the market, and endless big race wins. The V21 now rocks the longest, highest torque rotor, built to ROAR specifications. The extra length creates a bigger magetic field towards the middle of the rotor. This generates more torque when accelerating out of the corners and when jumping in off-road. When properly geared, this also allows the motor to run more efficient and in effect run cooler. The longer length measuring 25.9mm is at the absolute limit of the ROAR specification. This required us to shorten the back space near the sensor board, we also shortened the sensor board to center the rotor to the stator. All this was done while allowing the rotor to have an optimal gap spacing against the sensor board. 

This comes with the following:

1 x  Long 12.5mm x 25.9mm rotor
