Uses a very high gear ratio with fast sensorless motors to avoid startup "cogging" associated with sensorless R/C type controllers, then a low gear ratio for top speed and powerband. Each motor powers a Vex "Ball Shifter" 2 speed transmission, which powers 1 rear wheel wheel. Shifting is mechanical.
