Precision Torque from the Tamiya 42191 Transpeed

The Tamiya 42191 Transpeed sensored brushless motor focuses on smooth power and adjustability for competitive drivers. Its construction supports reliable throttle control across both touring and buggy platforms.

Advanced Octa-Wind Configuration

The octa-wind layout in the Tamiya 42191 enhances efficiency and reduces torque ripple for cleaner acceleration. The motor uses a 12.5mm sintered magnet on a reinforced shaft to maintain strong midrange drive.

Flexible Sensor Arrangement

The sensor positioning system can be fine tuned or replaced to suit different ESCs and driving styles, allowing you to adapt response and timing without major modifications.

Thermal Management with Front Cover

To keep output steady during long sessions, the front cooling cover helps move heat away from the windings so performance stays consistent heat after heat.

Specifications

  • Motor Type: 4.5T, 5.0T, 7.5T, 8.5T, 9.5T
  • KV Rate: 7,700 (4.5T), 7,000 (5.0T), 4,700 (7.5T), 4,100 (8.5T), 3,800 (9.5T)
  • Compatibility: Touring Cars and Buggy Machines

Ideal for racers who value tunability and consistent thermal behaviour, the Tamiya 42191 Transpeed is a dependable sensored option for various RC rigs.

High quality LiPo packs with an ESC rated for the pack voltage are best to deliver consistent current and minimise voltage sag during hard acceleration.
Sensor timing adjustments change start and midrange behaviour; small timing increases can add top end, while lower timing helps with smooth throttle control.
Check bearings, ensure the cooling cover is free of debris, and inspect sensor wiring periodically to prevent failures during events.
Yes, pairing the motor with a sensored ESC allows you to exploit its smooth low end and precise throttle modulation for better control off the line.
