It was always a drag for me in the field, to be deprived from the basic status messages of my flight controller. Many a problem could have been avoided with this information. Everything is just clear now. It is a quantum leap for my work with planes and flight controllers.Roland

FlightDeck is an OpenTX app designed for the Pixhawk, Pixhawk 2.1 “The Cube” and other flight controllers running ArduPilot flight stack. Linux-based flight controllers are not guaranteed to work.

FlightDeck also works on the PX4 flight stack when using a Teensy connected via MAVLink and flashed with this project:

Telemetry cables can be used on the ArduPilot and the PX4 flight stacks (without FlightDeck) to get basic Smart Port telemetry displayed on a compatible radio controller (Taranis and others).
