the work on my self-designed 3D printed hexacopter has been finished:) Some pics attached.
It can fly pretty well in all modes but I wanted to tune it with the Autotune functionality.
After the drone took off I switched to Althold and turned on the Autotune (Ch7). The drone tuned the PIDs for Roll for about 4 minutes and than... tried to fly away. I managed to put it to the ground by reducing throttle and disarming - it worked, uff.
After re-arming and checking the throttle on the ground I watched a strange behaviour - the drone tried to put the throttle to full when I only touched the throttle stick on the transmitter.
Now I am wondering what happened in the air and what is wrong with the configuration causing this strange throttle behaviour. I do not want to fly the drone until that's not clear for me and the issue solved.
Can someone with more experience maye help me on this?
I attached the log file from the fatal flight. Many thanks for any hint and suggestion.
BTW. I checked the PIDs and they stayed unchanged means autotune did not write any new values.
