RPM (revolution speed) sensor RPMS-01

Again it's quite small, for an optical device anyway.
On my Eagle Tree logger I found the RPM sensor to be quite useful, and I suspect this sensor will be useful on the FrSky hub system.
One thing occurred to me right away is monitoring head speed in flight with my helicopter. I'll try pointing it up through the main rotor arc or through the main gear. Normally it's used to measure propeller RPM on a plane.
