Yokomo RP-109A Spacers for Longer Motor Service Life

Serious RC drivers running Racing Performer M4/M3 motors can fit Yokomo RP-109A spacers to cut down on spacer wear. These stainless steel replacements for the RP-091 shims are aimed at improving long term reliability around the rotor and sensor area.

How Stainless Spacers Help

Brass shims are more prone to wear under hard use, which can affect sensor clearance. The RP-109A stainless steel spacers resist this wear better, helping to maintain accurate sensor positions and steadier motor output.

Care and Inspection Guidelines

Include spacer checks in your routine motor maintenance and replace any pieces that show thinning or scoring. Keeping the rotor spacing correct with RP-109A spacers reduces the likelihood of sensor faults and preserves motor performance.

Comparing RP-109A to RP-091

In direct comparison to RP-091 parts, RP-109A spacers typically last longer and provide more consistent spacing under load. That leads to fewer service interruptions and more predictable behaviour during races or practice.

Specifications

  • Material: Stainless Steel
  • Compatible With: Racing Performer M4/M3 Motors
  • Purpose: Protects sensors and enhances motor performance

The Yokomo RP-109A spacers are a concise, effective upgrade for those who want to reduce component wear. Fitting them helps ensure Racing Performer motors remain consistent lap after lap.
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.

Which model do these spacers suit?

They are intended for use with Yokomo Racing Performer M4 and M3 series motors. Confirm your motor series before purchase to ensure fitment.

Will they work on older motors?

If the older motor shares the same spacer dimensions as the M4/M3 series, they may fit, but always verify spacing and clearance before final assembly.

How do I spot worn spacers?

Look for reduced thickness, uneven edges or grooves on the spacer face. Any of these signs indicate it's time to replace the shim to avoid sensor problems.

Do these spacers affect motor tuning?

They do not alter electrical tuning, but by preserving correct rotor spacing and sensor alignment, they help the motor perform consistently to your chosen setup.
