Tamiya 42188 Transpeed Octa-Wind 5.0T Brushless Motor Kit  [42188]

Overview of the Tamiya Transpeed Motor Line

Designed for club racers and seasoned hobbyists, the Tamiya Transpeed series blends precision engineering with race-ready design. The 42188 model highlights Tamiya's focus on sensored brushless technology and high quality construction for consistent track performance.

High-precision sensored motor construction

The core of this range is a sensored brushless layout using an OCTA winding arrangement and a 12.5mm sintered magnet to balance torque and efficiency. The sensor mount is adjustable and replaceable, allowing fine tuning of commutation timing for smooth throttle response and repeatable laps.

Cooled front cover for longer sessions

The 42188 includes a front cooling cover that helps keep internal temperatures down during extended runs. That thermal control, combined with the available turn options such as 4.5T and 5.0T, makes the motor suitable for high speed touring car setups where overheating is a concern.

Optimised for touring car setups

While 42188 is focused on touring car applications, Tamiya's Transpeed family includes nearby part numbers that cover buggies and mixed use. This gives racers flexibility to pick the turn count and form factor that matches their circuit and driving style.

Experienced drivers seeking a durable, responsive motor for asphalt touring cars will find the Tamiya Transpeed 42188 balances power, efficiency, and temperature control for competitive running.
