Compact Power: Tamiya 42158 Brushless Motor

For racers who want compact, reliable torque, the Tamiya 42158 brushless motor is built to deliver measured power under racing loads. The 12mm rotor helps the motor stay efficient while providing responsive throttle control.

Windings and Performance Options

Available in 6.5T through 9.5T windings, these motors let you tailor the RPM and KV characteristics to your vehicle and course. Adjustments in winding selection help balance acceleration versus top speed for different race formats.

Setup Intended for Skilled Users

These units require experienced setup including soldered connections and precise ESC programming. They are not suited to drift driving and pair best with Tamiya Volac Brushless or Volac Brushless BL2 ESC systems for predictable behaviour.

Tamiya 42158 motors give experienced hobbyists a dependable balance of torque and efficiency for race setups. Correct installation and ESC pairing are key to unlocking consistent lap times.

Start with a mid-range winding like 7.5T to learn how the motor behaves, then move up or down based on torque needs and top speed.
Yes, with proper cooling and not running at maximum continuous load they handle extended sessions, but monitor temperatures during long runs.
Upgrading to higher quality bearings and secure connectors can improve smoothness and longevity, just ensure parts match motor dimensions.
Matching the motor to a compatible ESC like the Tamiya Volac Brushless or Volac Brushless BL2 ensures correct timing and thermal handling, which is important for consistent performance.
