yesterday I tried to autotune my big x8 with KDE 7208 110KV Motors and Kde 75A esc (setup for the 7208) with 27" KDE Props.
The behavior before autotune was not rock solide, but it was flying and I thought it would be ok to switch to autotune.
After 5 minutes of tuning, I had the impression that it gets more stable.
But then the drone turned on yaw axis lost altitude. I switched instantly to althold but I couldn't trap it.
The feeling was like the batterie gets to empty, but this was not reason.
I had a realy hard "landing" with broken landing gear and all of the expensive KDE props.
The only mistake I made was that it set "AUTOTUNE_AGGR" to 0.10.
Clould somebody please have a look at my log file?
