Choice of stars
The Vortex MR8 motors have been chosen by many 1/8 nitro stars for their electric cars. They worked closely together with our R&D manager Oscar Jansen to develop the next generation brushless motors.

4-Pole Brushless Power
Power is good, control is better - the MR8 motors have both! Thanks to a sophisticated 4-pole system, the MR8 motors deliver best power and control at every throttle position. The motors reach an efficiency of up to 90%.

The "oversized" MR8L will give your Truggy or Monster truck the ultimate power. The 1500kV version can
handle up to 6S while the other motors should be used with batteries with up to 4 cells LiPo.
Please check the dimensions to be sure the MR8L motor fits your car.
