Precision rotor option for Yokomo RP-057A users

RC drivers looking to squeeze tighter lap times can fit the Yokomo RP-057A Racing Performer Rotor #57 M3 D12.5xd7.25. It is built to slot into Racing Performer M3 motors and deliver a more aggressive performance envelope.

Engineered magnet for quicker response

The rotor features a compact high-power magnet that improves launch speed and helps maintain momentum on straights. The key dimensions are a 12.5mm outer diameter and a 7.25mm inner diameter, which support stronger acceleration characteristics.

Durability under sustained running

Designed to resist demagnetisation at higher temperatures, this rotor keeps motor output steady during long runs. If magnetic strength falls, swapping the rotor refreshes the motor's original responsiveness.

Setup suggestions from experienced racers

Match this rotor with an appropriately tuned ESC, sensible gear ratios and stable damping to fully use its extra acceleration without upsetting handling into corners.

Specifications

  • Magnet Outer Diameter: 12.5mm
  • Magnet Inner Diameter: 7.25mm
  • Compatibility: Racing Performer M3 Series Motors

For club racers or weekend enthusiasts, the Yokomo RP-057A Racing Performer rotor gives a noticeable boost to throttle response while remaining a simple upgrade to fit.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this rotor fit my M3 motor?

Yes, it is designed for Racing Performer M3 series motors. Double check shaft and endbell compatibility before fitting to ensure a correct match.

Does it affect motor temperature?

The rotor is engineered to retain magnetic force at higher temperatures, but extra acceleration can increase motor load so monitor temps and cooling during long runs.

Should I change gearing after fitting?

You may want to adjust pinion or spur to balance acceleration and top speed. Test a couple of ratios on the track to find the best compromise for your setup.

How often should I replace the rotor?

Replace the rotor if you notice reduced punch or inconsistent power. Regular inspections after heavy use will help you catch wear early.
