Tamiya 42154 Brushless Motor for Technical Crawling

The Tamiya 42154 Transpeed B-less R Stock 21.5T motor targets hobbyists who need controllable low-speed power in rock crawling scenarios. It emphasises torque and smooth throttle feel to help with technical moves on tricky surfaces.

Engineered for Controlled Crawls

Fitted with a robust neodymium magnet, the Tamiya 42154 delivers strong torque tailored to crawler duties. The motor includes a JST connector wiring harness for quick connection and tidy cable runs during installation.

Use with CR-01 and Slow-Speed Chassis

Suitable for the CR-01 chassis and similar slow-speed rigs, this motor's 1,600 KV rating supports efficient torque output for slow, precise driving rather than high-speed performance.

Specifications

  • Magnet Type: Neodymium
  • KV Rate: 1,600
  • Connector Type: JST

A sensible upgrade for off-road crawling setups, the Tamiya 42154 improves torque delivery and fine throttle control for technical trails.

Do I need a special ESC for this motor?

A crawler-friendly brushless ESC is recommended, particularly one that supports low-speed control and adjustable throttle curves. Standard brushless ESCs can work if tuned appropriately.

What pinion size should I start with?

Start with a conservative pinion that gives good gear mesh and enough torque for crawling. You can experiment with smaller or larger pinions depending on terrain and load.

How hot will the motor run during climbs?

Temperature depends on load and gearing. Monitor heat during extended climbs and allow cooling periods; proper gearing and ESC setup reduce overheating risk.
