I am working on a project which includes an autonomous mission of an hexacopter using PX4, Mission Planner and Python scripting. In this flight, the RC is not necessary and the hexacopter flies just via Python scripting and Mission Planner commands communicating with an RF telemetry link.
My main concern is how can i retake the copter’s control via Remote Controller in a scenario where the auto mission is not working while the copter is in the air. Specifically, if for exampe there is a communication breakdown between copter and GCS while the copter is in the air , is it possible to control the copter from the radio controller so not to have my vehicle crashed?

I tried to retake copter’s control by changing modes from RC while it executes the flight by it doesn’t seems to work.

Any help please?

Thanks for your time
