Futaba BPS-1 RPM sensor eliminates the fan mounted magnets and mounting stays typically used for governors and puts the sensor into the back plate of the engine.

This provides accurate RPM readings without the hassle.

Designed for use with the Futaba GY701 and the CGY750 on the O.S. 55HZ-R and 91HZ-R engines with the built-in sensor mount.

The newer style back plate is also available from O.S. for older 55 and 91 engines.
