Description
An optional rotor for racing performer M3 series motors that can adjust the power feeling according to the race regulation. With a magnet outer diameter of 12.0 mm and an inner diameter of 7.25 mm, a high-power magnet that achieves overwhelming acceleration and top speed is used to build an advantage in racing.
Even if the magnetic force is lost due to high temperature, the motor power is refreshed by replacing the rotor! It is possible to regain the original power and feeling.
