Rotor magnetic-force gauge for RC motors

The Yokomo FA-28500 jp is a compact RC motor checker built to measure the magnetic force of a motor rotor, a key factor that influences throttle feel and tuning choices.

By quantifying rotor magnetic strength the unit helps with setup decisions such as selecting gear ratios, refining throttle response, and matching motors across a fleet. Its readings guide mechanical and electronic adjustments without requiring any motor disassembly.

Designed for both brushless and brushed RC motors at model scale, the FA-28500 jp serves as a bench diagnostic during inspections and pre-event setup checks.

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 exactly does the FA-28500 jp measure?

It measures the magnetic pull or force of a motor rotor so you can assess magnet strength and uniformity, which affect motor response and consistency.

Which types of RC motors work with this tester?

The tester is intended for model-scale brushless and brushed motors; check the compatibility list for the specific rotor models supported when preparing bench checks.

How should I use readings to change setup?

Compare readings between motors to inform gear ratio choices and ESC throttle mapping. Stronger rotors may deliver quicker response, so use values as a relative guide.

Any special care for the unit and rotors?

Keep the tester clean and dry, avoid exposure to external strong magnets, and handle rotors gently during measurement to prevent damage.
