RP-021 Technical Summary

The Yokomo RP-021 serves as a drop-in rotor for the Racing Performer series of scale RC motors, matching the line's magnet specifications: 12.5mm outer diameter, 5.00mm inner diameter, and 25.3mm magnet length. This ensures the same form factor where Racing Performer rotors are used.

This rotor is suitable when renewing an original Racing Performer unit or when replacing one that is damaged. During installation, verify the inner bore aligns with your motor shaft and confirm there is adequate clearance between the rotor and the motor can and bearings before powering the motor.

The component is intended solely for scale RC motor maintenance and tuning, not for full-size vehicle use.

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.

How robust is the RP-021 under standard use?

The RP-021 is manufactured to match the original Racing Performer dimensions; when installed correctly and used within normal RC motor conditions it provides reliable service. Always ensure bearings and shaft are in good condition to avoid premature wear.

Can I reuse the old bearings with this rotor?

If the bearings show no play, roughness, or corrosion they can be reused. However, replacing worn bearings at the same time as the rotor is recommended for best longevity.

What signs indicate rotor damage?

Look for cracked magnets, chipped edges, loose magnet bonding or any metal fragments. Any of these warrant replacement to prevent further motor damage.

How should I store spare rotors?

Keep rotors in a dry, dust-free container and avoid dropping them. Protect magnet faces from impact and keep them separated from ferrous tools to prevent damage.
