Remark :
Due to limited stock availability, please notice that some Kyosho 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.

What checks should I do before fitting this motor?

Verify mount hole alignment for M2 screws and confirm the 20mm diameter will clear surrounding chassis parts. Measure shaft coupling to ensure a secure match.

Can I upgrade bearings later on?

The motor already uses ball bearings, but if wear appears you can replace them with matching-size bearings following standard disassembly procedures.

Which maintenance steps keep performance consistent?

Keep bearings clean and lightly lubricated, check screw tightness regularly, and avoid water exposure to maintain smooth operation over time.
