For Frsky X9D, 9XR and other transmitter Hitec, JR, Futaba Series Remote control Use
The 6 position switch can be installed in place of your S1 or S2 pots at the top of your Taranis radio. The result will be a 6 position rotary switch that can be used for flight modes, flap positions, or whatever you can think of. Users asked for this feature, and FrSky listened. These are so new I do not have many details about installing them. Will require basic soldering to install.
Note: While the switches can be made to work via custom curves, etc. The new firmware (OpenTX 2.0) will make this switch much more functional.
