Romeo Eftemie replied to MR's discussion Expensive crash on X8 due sudden uncontrolled YAW (Pictures + logs added)
"Hey MR, this looks suspiciously similar to what happened to my friend's quad.
Looking at the logs, I see RCIN C4 centered but at the same time under ATT the DesYaw gets the quad spinning.
The same thing happened in our case, with no control when it…"

Hello,One of my friends has a quadcopter that developed a strange behavior. All of a sudden, the only thing it does it rises about 50cm to 1m and spins clockwise, without any response to inputs. Today we did a full erase and install of 3.2.1, redone…

"That was the altitude when it happened the first time. The copter flew perfect in both stab and althold for at least 4 flights prior to adding the GPS+mag. That was my understanding as well, mag not affecting the pitch/roll and I'm not saying it is,…"

"Thanks for looking, I think the log is not complete since the battery got ejected on the way down.
Apart from the pitch and roll not following perfectly, although in the air the copter is flying good, the only thing out of the ordinary I find in…"
