FrSky Opto RPM ADV

This optical RPM sensor is a pretty simple, point it at your prop and and it will report how many RPMs the prop is turning. Don't forget to adjust the count for the number of blades. A great power system tuning aid.

The OPTO RPM ADV sensor can be used to measure rotational speed. When connected directly to a receiver with the S.Port/FBUS port, telemetry data can be transmitted and read by compatible radios. Alternatively, when the sensor is switched to PWM mode, it can pass the rotation data through to a device port that supports RPM calculation, achieving the same purpose of RPM data collection.

FrSky ADVANCE (ADV) series has comprehensive sensor types and enhanced the performance and capability of the original sensor line, all ADV sensors fully support FBUS protocol and they are also S.Port compatible. With the FBUS protocol, the ADV sensors can be seamlessly paired with the FBUS-capable receiver and further simplifying the builds setup.
