Will I need to change gearing when fitting this motor?

You may need to adjust pinion or spur gear ratios to match track layout and battery choice. Small changes to gearing can help tame top speed or improve acceleration depending on conditions.

Is there a break-in procedure for this brushless motor?

With brushless motors a gentle run schedule for the first few packs is sensible: moderate speed runs and checks for secure mounting, wiring and bearing smoothness will help confirm the setup.

What routine maintenance does this motor need?

Regular checks include ensuring screws are tight, connectors are secure, and bearings spin freely. Keep the motor free of dust and inspect after any impact to avoid performance loss.
