The Yokomo RP-056A rotor is an optional upgrade aimed at hobbyists and racers who want to tailor their Racing Performer M3 motor characteristics. It offers adjustable magnet strength so you can comply with class limits or change the delivery of power for specific circuits.
With a 12.5mm outer diameter and a 5.00mm inner diameter, the RP-056A incorporates a high-power magnet to increase acceleration and top speed. That extra drive makes a difference during tight races and long straights alike.
Designed to cope with heat from intense use, the RP-056A keeps performance predictable even under stress. If the magnet loses strength over time, you can replace the rotor alone to return the motor to its original behaviour without major expense.
For club racers and keen model builders, the Yokomo RP-056A rotor is a pragmatic way to tune a Racing Performer M3 motor for class compliance and improved track performance.
