Hey guys
It's been the second time I had this problem, my copter stop during a survey mission in auto mode and switch to loiter.
My setup is an octocopter, controlled by a Dropix from Drotek running Arducopter 3.4.6.
I was pretty far away this time, so not the best RC reception, but on the first flight the drone was never more than 200m away and I had great signal on my Taranis.
It could be the FrSky X8 receiver, a sort of fail safe that would change the value on the Auto switch, but never happened on any of my drones before, a bug on the Arducopter 3.4.6 or my Dropix having problems. I have no idea... Image may be NSFW.
Clik here to view.Thanks
Ben
PS : over all, I did 8 auto flight and it happened twice
Update 1 : I checked the RCIN in the log, Chan 5 "mode change" and Chan 8 "Auto" went, in PWM, from 982 to 874 and 2006 to 1323 respectively in less than a second then went back normal again, immediately after that the mode change from auto to loiter. No problem with all the other channel even Chan 7 "RTL"
