I am looking for a radio module for Pixhawk4. The project is about to get a plane flown by autopilot (Ardupilot).
What module can you recommend for sending telemetry data (alltitude, lat, long, speed etc) to the ground station (QGC) and for sending control commands (speed, heading, roll, yaw, pitch, etc) back to the plane?
Because I am in Germany, there are some restrictions concerning the use of radio modules.
Do you know a suited module which is legal to operate in Germany?
Thanks a lot for your contributions.
