Rotor magnetic-force tester for RC motors

The Yokomo FA-28500 jp is an RC-scale motor checker designed to quantify the magnetic force of a motor rotor, a primary characteristic that affects motor response and tuning decisions.

This tester evaluates rotor magnetic strength to help with setup choices such as gear ratio selection, throttle response tuning, and overall motor matching within an electric RC system. Readings from the unit inform mechanical and electronic adjustments without altering the motor itself.

Intended use is inspection and tuning support for brushless and brushed RC motors at model scale; the tool is a diagnostic aid during bench checks and pre-race setup sessions.

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 does this tester measure?

It measures the magnetic force of the motor rotor to indicate rotor strength and uniformity important for tuning decisions.

Which RC motors is it used with?

The device is intended for RC-scale motors; check compatibility with your chassis and motor types during setup and inspection.

How do readings affect setup choices?

Magnetic-force readings help decide gear ratios and electronic settings by indicating rotor strength and consistency compared to reference motors.

Any maintenance or care required?

Keep the tester clean and dry, store it protected from strong magnetic fields, and handle rotors carefully during measurement to avoid damage.
