I have a question.Firstly My flight controller is PX4 . When I use QGC to set flight mode,I cannot set land mode，hold mode.but i can set takeoff mode,attitue mode and use them. my flight is flying indoors without GPS,I know that if you want to use land mode and takeoff mode, you must have a gps signal, but now I want to set the land mode on the aircraft through the QGC. It's just a setup, it can't be implemented.
Like this, the remote control mode is land but the aircraft's mode is still the last takeoff mode.
If someone answers, I will be very grateful
