GM Racing Brushless Pro 6T motor

GM Racing Brushless Pro motors

We recently told you about the new range of Brushless Pro motors from GM Racing, but to add to the range that was already announced, a 6T version is also now available. This is the motor the current British Champion Chris Grainger has been using recently with great success, winning the recent Aldershot BRCA National. The 6T delta winding is equivalent to a regular 3T, with the delta type winding giving greater efficiency and therefore run time over the normal Y type winding as per most current brushless motors. Pricing on this motor is also extremely competitive but does not reflect its awesome performance.
