The Smart Port Brushles RPM and dual temperature sensor plugs it into a Smart Port equipped receiver (X series, 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 too? 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!
