Yikong 14T Pinion Gear

The Yikong 14T Pinion Gear (SCH-YK21051) is a straightforward replacement or tuning option for radio-controlled models that require a 14-tooth pinion. Use it to adjust your final drive ratio when balancing acceleration, top speed and motor temperatures. It is a genuine Yikong spare part suited to routine maintenance and gearing changes.

Usage Notes

• Confirm the required gear pitch/module and motor shaft diameter for your specific model and motor.
• Check your kit manual for recommended gearing and safe operating temperatures.
• A 14T pinion typically offers stronger punch than higher-tooth options at the expense of top speed; always monitor temperatures after changes.
• If your application uses a set/grub screw, apply a suitable thread locker and set a correct gear mesh.
