Consistent Lap Pace with the Tamiya 42187 Transpeed Octa-Wind

The Tamiya 42187 RC Transpeed Octa-Wind 4.5T Brushless Motor is aimed at touring car pilots seeking steady power delivery and good thermal stability. OCTA winding plus the 12.5mm magnet provides an efficient torque curve useful for tight circuit work.

Construction and Cooling Details

The motor incorporates an adjustable and replaceable precision sensor positioning system so you can tweak start behaviour and throttle feel. The sintered 12.5mm magnet is mounted on a reinforced shaft for dependable operation, and the special front cooling cover helps manage heat during prolonged running.

Specifications

  • Motor Type: 4.5T
  • KV Rate: 7,700
  • Magnet Size: 12.5mm
  • Compatibility: Touring Cars

When used in a tuned touring package, the Tamiya 42187 supports consistent performance and controlled temperature behaviour for race days or practice sessions.

Does this motor require a specific ESC type?

Use an ESC that supports sensored inputs and can handle the 4.5T power curve; verify timing and motor settings to suit your battery and gearing.

Are there break-in steps for the sintered magnet?

Run gentle, short sessions initially to stabilise bearings and observe temperature trends before full-throttle runs to ensure reliable seating of components.

Will the front cooling cover affect body fitment?

The cooling cover is compact but check body shell clearance during installation to ensure it does not interfere with airflow or chassis parts.
