The FrSky Smart Port RPM and Dual Temperature Sensor plugs into the Smart Port on your X series receiver and reports brushless motor and dual temperatures on the FrSky Taranis.

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!

Great way to get RPM readings

My shopping experience at Aloft has never been anything but great. Great service and great products. This temp & rpm sensor is another example of the affordable and worthwhile (make that indispensable) equipment Aloft offers. With a little research, I found out how to connect the RPM leads to the Gas Ignition tach output and now I have reliable tachometer and temperature readings on my Dle 35. The tach readings are much more stable than the readout from a handheld optical tach. This link will explain that all you need is an inexpensive capacitor: https://www.rcgroups.com/forums/showthread.php?2884780-IC-engine-and-FrSky-smartport-RPM-sensor-A-coil-works%21-A-capacitor-works-better%21/page2#post39141981 Very simple and easy to do if you know how to solder. Thank you Aloft and Frsky for another great product!

RPM and temp sensor.

Excellent service. Prompt shipping. Both worked as advertised. Temp sensors are quite impressive. Very thin and quite accurate.
