Futaba FUSBS-01RM Handheld Magnetic RPM Sensor for RC Models  [FUSBS-01RM]

Hands-on RPM readings for model setups

The Futaba FUSBS-01RM functions as a magnetic rotation RPM sensor and portable tachometer for model-scale applications, capable of measuring from 360 up to 50000 RPM. It is intended as a bench tool to help diagnose motor response, check ESC adjustments, and verify tuning steps.

Fitting is simple: align the magnetic pickup so it senses the rotating magnet or ferrous target, secure its position to avoid movement, and route the connection into your receiver accessory arrangement. The device is designed for hobby RC use and should not be used on full-size vehicles.

Use the FUSBS-01RM during tuning to log RPM shifts after gear or timing changes, compare different motor setups, and set reference values before live testing. It pairs well with methodical ESC and mounting checks to validate changes.

As a compact measurement aid, the FUSBS-01RM slots into routine RC setup tasks and bench testing without complex configuration; rely on it for comparative RPM data rather than as a complete substitute for evaluating performance under load.
