Hello! Can someone please indulge of the importance of a transmitter despite flying autonomously. Thank you
Flying without an transmitter might be illegal in your country.
Anyhow, it is always possible that errors occur which require manual controll (e.g. GNSS problems).
I prefere to operate the vehicle by a RC transmitter because I’m faster and I have a manual.
Return-To-Home. You can also use a laptop in scenarios where the hardware is compatible.
If you have a working GNSS.
True, but it is VERY unlikely that you would ever lose all GNSS constellations or have a board fry.
