FrSky SP-RPM - RPM and Dual Temperature Sensor

The Smart Port Brushless RPM and dual temperature sensor plugs into a Smart Port equipped receiver (X series, it will not work with D series receivers). Join the red and black wires to any 2 of the 3 wires going to your brushless motor, and you can now read the RPMs. You will need to identify how many poles your motor has and that is about it.  Now you can fine tune your prop/motor/battery combinations without guessing anymore! See what that prop is actually doing in the air. But FrSky has even more to offer. What good is knowing the RPM if we don't know how our temps are doing as well? So FrSky has included not one, but 2 temperature sensors. Now we can make sure our new prop is not cooking our speed control or battery! 

Early Taranis transmitter users may require a firmware update to take full advantage of this sensor.

Here is a great video from one of our customers. This video will outline the steps to use the RPM features of this sensor with your brushless motor. Thanks RCdiy!!
