As described in the title, i cant change the flight mode 6 in the mission planner under flight mode config. Its locked with 'manual' mode. I got a copter running to, there i can change all flight modes, so i dont know whats the reason to lock flight mode 6 for Arduplane to manual.
I managed my 9x to switch all 6 modes, and in 0 position i like to have the 'manual' mode, now i got it on position 6 too.
Any chance to change this ?
