Product overview

The Yokomo YOKRPM-B45 is a brushless motor specified as 4.5T and positioned for racing performance in RC car applications. This article focuses on the motor's role in vehicle setup, installation considerations, and tuning impact rather than retail claims or unverifiable performance figures. The description treats the unit strictly as an RC-scale component for car models.

Compatibility decisions for a motor depend on can size, mounting pattern, pinion fitment, and ESC support. Use the YOKRPM-B45 as a direct replacement where the motor can and screw layout match your car's motor mount, and ensure your ESC supports sensorless brushless motors with the chosen battery and gearing.

When fitting a 4.5T motor like the YOKRPM-B45, expect tuning to centre on gearing, ESC timing, and battery selection to balance acceleration and sustained top speed for your chosen track type. Fine adjustments to gear ratio and throttle curves typically yield the most predictable on-track behaviour without hardware modification.

Specifications

  • Item: Racing Perf. M2 Brushless Motor 4.5T
  • Material: Not specified by manufacturer
  • Model Number: YOKRPM-B45
  • Compatibility: Car motors for RC car applications

As an RC car brushless motor, the YOKRPM-B45 provides a 4.5T winding option for drivers focused on track-oriented tuning; verify physical fit and ESC compatibility before installation and prioritise 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.

Will the YOKRPM-B45 fit my RC car motor mount?

Check the motor can diameter and mounting hole pattern against your chassis motor plate, measure pinion shaft diameter, and confirm screw positions before purchase.

What ESC settings should I start with for a 4.5T motor?

Begin with conservative throttle endpoints and neutral timing, then adjust timing and punch to suit the track; consult your ESC manual for sensorless brushless presets.

Does the motor require specific batteries?

The motor itself does not mandate a battery chemistry, but match battery voltage and discharge capability to your ESC and gearing choices to avoid excessive current draw.

How does gearing affect a 4.5T motor's behaviour?

Lower gear ratios increase acceleration and motor load, higher ratios raise top speed and reduce load; adjust incrementally and monitor motor temperature during runs.
