Flight mode 6 not changeable / locked in APM mission planner ?

Posted by IronStone on June 3, 2012 at 11:31am

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 ?

    Hello!

    Actually unfortunately I am always having HOLD as current mode and also shows HOLD in Failsafe mode. I can't find out the reason behind it. Can you help me?

    Hi,


    Mode 6 is not changeable because at that setting (>1750ms PWM pulse-width), a hardware manual override is invoked and chan 1-4 are passed straight to the servos and not into the APM at all. I understand this is done within the PWM encoder, (another avr chip?) and is completely outside of the APM's control. I believe it's purpose is to allow a manual takeover should the APM malfunction (e.g. crashes during code development etc).

    What I can suggest is that you reverse the servo output of your channel 8, so you can use just mode 6 for manual instead of mode 0, and still have the stick in the desired position, this is what I did on my 9x. (manual is all switches 'back').

    Hope this helps,
