If you are preparing a touring car for competitive use, the Tamiya 42187 offers a dependable mix of thermal control and sustained rpm to help improve lap consistency.

What gear ratio should I try first?

Begin with a conservative pinion that keeps motor load moderate, then adjust to suit your track layout and ESC limits while watching temperatures.

How do I check sensor alignment?

Verify the sensor position against the motor housing markings and test startup behavior; adjust the replaceable sensor mount if you notice cogging or inconsistent starts.

Is the Tamiya 42187 robust for regular club racing?

Yes, its reinforced shaft and sintered magnet construction are intended to handle repeated race use, provided you maintain proper cooling and avoid overloads.

Will this motor fit in my current mount without modification?

Most 1/10 touring car mounts accept this motor, but check shaft position and pinion clearance when swapping motors to ensure correct mesh and body clearance.

How often should I inspect the motor after racing?

Inspect bearings, shaft play and the cooling cover after each race day, and clean any debris to maintain performance and prevent overheating.
