Suitable for competitive club racers and dedicated hobbyists, the Tamiya 42189 delivers a balance of torque and efficiency for varied racing formats.

How does the 12.5mm magnet affect braking and acceleration?

A larger 12.5mm magnet increases magnetic flux, which typically improves torque for acceleration and provides more controllable braking feel under regenerative or motor braking setups.

Are bearings and mount hardware standard sizes?

Bearings and mounting hardware follow common hobby dimensions, but verify sizes against your car to ensure direct fitment without modification.

What should I check before a race day installation?

Confirm motor mount alignment, sensor positioning, secure fastenings, and suitable ESC settings. Run a short shakedown to check temperatures and drivetrain smoothness before full competition use.
