MR33 Drivetrain Checker

MR33, the brand of multiple World Champion Marc Rheinard, has released this Drivetrain Checker which makes it finally possible to measure and check 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 step on the gas. Now just read the displayed value on the display, and the job is done in 5 seconds. Simple and uncomplicated, for example, as part of the technical inspection before the run. If only the engine sensor is applied and the throttle is opened, the (maximum) engine speed can be measured – perfect for testing speed limits of modern speed controllers.
