FrSky sensors and Spirit Systems heli flybarless units

Spirit Systems produce awesome flybarless units for RC helicopter models. Per default Spirit units provide great support for OpenTX and FrSky gear. You can easily get telemetry from Spirit (also from connected ESC, like Hobbywing) and flawless OpenTX integration, which allows to set all Spirit parameters directly from FrSky radio (Horus or Taranis), using provided LUA script.

Things get a bit complicated if – in the same time – one would like to use standard FrSky telemetry sensors. In example if you connect FrSky GPS v2 sensor, it will collide with virtual telemetry sensors provided by Spirit flybarless unit, resulting in blocking telemetry signals from Spirit virtual sensors.

Fortunately there is simple workaround and in this article I will cover some of FrSky sensors, describing how I made them work with Spirit and standard Smart Port telemetry in FrSky / OpenTX.
