Steady Power Delivery from Yokomo YM-PS221A

The Yokomo YM-PS221A Pro Stock 2 Motor is engineered to give consistent torque and predictable throttle response for dedicated RC drivers. The 21-turn double winding produces usable pull for improved corner exits while remaining controllable at speed. Robust construction keeps performance steady across repeated runs.

Why the 21T Choice Works

The 21T specification offers a sensible compromise between acceleration and top speed for 1/10 scale applications. Double winding helps maintain thermal stability and smooth output during competitive stints. It is a practical upgrade for those seeking improved driveability over basic stock motors.

Practical Tips for Setup and Use

Match the YM-PS221A with an ESC that handles 21T motor settings and fine-tune gearing to suit your circuit. Keep clear airflow and inspect the motor regularly to avoid debris build-up. This motor suits tight technical tracks where torque control improves lap consistency.
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 the YM-PS221A fit standard Pro Stock motor mounts?

It is designed around the Pro Stock form factor, so it will fit most standard mounts that accept this motor type. Always check clearances and shaft alignment.

How often should I inspect the motor?

Inspect brushes, commutator and mounting after several race sessions or if you notice power loss or unusual noise. Routine checks help prevent issues mid-event.

Are there simple tuning tweaks to improve performance?

Adjusting pinion size and ESC timing, plus ensuring sufficient cooling, are common ways to tailor performance to your track and driving style.
