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

Precision magnetic RPM sensor for bench tuning

The Futaba FUSBS-01RM is an RC-scale magnetic rotation RPM sensor and handheld tachometer designed to read rotational speed between 360 and 50000 RPM. Built for use with model-grade setups, it serves as a diagnostic aid when checking motor behaviour, verifying ESC calibration, or validating tuning changes on the bench.

Installation is straightforward: position the sensor near the rotating element so the magnetic pickup senses the passing magnet or ferrous target, keep the pickup aligned and stable, and route its connection into your setup as required by your receiver accessory layout. This unit is intended for hobby RC use and not for full-size vehicle applications.

For tuning workflows, the FUSBS-01RM provides quick RPM references that help compare motor and gear ratios, confirm the effects of pinion/spur changes, and establish baseline values before on-track testing. Use it alongside motor mounting checks and ESC timing adjustments to close the loop on measurable changes.

As a compact tachometer sensor, the FUSBS-01RM fits into routine RC tuning and bench testing without complex setup; treat it as a measurement tool to confirm adjustments rather than as a substitute for observing system behaviour under load.
