Yokomo FA-28501 Stator Meter for FA-series Chassis  [FA-28501]

Stator resistance and inductance tester

The Yokomo FA-28501 is an RC-scale stator meter designed to read two core electrical attributes of brushless motors: stator resistance and inductance. These parameters influence motor response and control behaviour, so having a dedicated measurement tool helps with repeatable motor setup and comparative checks between stators.

The unit is intended as a bench or pit-side diagnostic tool for model-scale electric motors and is used when selecting or verifying replacement stators or when comparing stators before final motor assembly. It reports resistance as a direct indicator of winding continuity and relative impedance, and inductance as the parameter that relates voltage and current change rates under drive conditions.

Installation is limited to connecting the meter to the motor stator leads per the meter’s connector scheme, and using steady hands to avoid shorting phases while probing. The device is compatible with a range of Yokomo FA-series chassis and is positioned as an aid during motor selection and electronic system tuning rather than a substitute for professional electrical lab equipment.

For hobbyists focused on consistent motor setup and stator comparison, the FA-28501 provides a focused set of measurements—resistance and inductance—that support informed tuning decisions on FA-series chassis.
