Product brief and tuning guidance

The Yokomo YOKRPM-B45 is a 4.5T brushless motor specified for performance use in RC car applications. The following notes address installation, setup choices, and the tuning effects you can expect rather than marketing claims, presenting the motor solely as a component for car models.

Compatibility requires checking can diameter, the motor mounting hole pattern, pinion fit, and ESC support for sensorless brushless motors. Use the YOKRPM-B45 where the can and screw pattern match your chassis and verify pinion and shaft dimensions before installation.

With a 4.5T motor such as the YOKRPM-B45, initial setup work typically concentrates on gear ratio, ESC timing, and battery selection to achieve the desired trade off between acceleration and sustained speed. Minor adjustments to gearing and throttle curves often produce the most consistent track results.

Specifications

  • Item: Racing Perf. M2 Brushless Motor 4.5T
  • Material: Not specified by manufacturer
  • Model Number: YOKRPM-B45

As an RC car brushless option, the YOKRPM-B45 delivers a 4.5T winding for drivers focused on track performance; confirm fitment and ESC compatibility before fitting and concentrate on gearing and throttle mapping during setup.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What ESC adjustments are a good starting point for a 4.5T motor?

Start with neutral timing and conservative throttle endpoints, then incrementally increase timing or punch based on track feedback while keeping an eye on current draw and temperature.

How should I set throttle curves for predictable power delivery?

Smooth throttle curves with modest initial punch help maintain control in corners; dial in midpoint and end-point settings gradually to match driver style and track grip.

Are there heat management tips for race days?

Monitor motor temperatures between runs, avoid sustained full throttle during initial setup, and consider airflow around the can or additional cooling if temperatures are consistently high.

What incremental changes should I make when tuning gearing?

Adjust by one or two teeth on the pinion or a small change to the spur, then test for temperature and lap time differences; avoid large jumps that can overload the motor or ESC.
