With the MR33 Drivetrain Checker it is finally possible to measure and control the gear ratio and motor speed of RC model cars powered by 2-pole brushless motors.

Simply place the motor sensor on the motor, put the 7mm wrench on the wheel nut of a driven wheel and accelerate.
Now just read the value shown on the display and the job is done in 5 seconds.
Simple and uncomplicated, for example as part of the scrutineering before the run.
