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

Practical diagnostic tachometer for RC hobbyists

The Futaba FUSBS-01RM acts as a magnetic rotation RPM sensor and portable tachometer for model-scale applications, capable of registering rotational speeds between 360 and 50000 RPM. It is intended to assist hobbyists in diagnosing motor behaviour, checking ESC adjustments, and confirming tuning changes on the bench.

To use, position the magnetic pickup so it can sense a passing magnet or ferrous target on the rotating part, maintain consistent alignment, and route the connection into your receiver accessory layout. This item is designed for RC hobby use and is not suitable for full-size vehicles.

For tuning, the FUSBS-01RM gives straightforward RPM feedback to track the effect of pinion or spur swaps and other adjustments, helping establish baselines before field testing. Use it in combination with mechanical checks and ESC tuning to validate measurable changes.

The compact FUSBS-01RM slots into routine setup and bench testing workflows without complex wiring; rely on it as a measurement aid while still assessing system performance under real load conditions.
