I build an rcexplorer like Tricopter.
Flew right out of the box 
but i wanted to have an more responsive Copter like my quad.
So i tried Auto Tune on CH7 just like with my quad.
The Tri started to dance one time right one time left than again right not rolling back.
I was to slow to rescue the copter.
I don´t want to waste another set op props and tail servo in auto tune.
Hope someone can tell by the log file what went wrong.

I had the exact same problem today. RCExplorer Tricopter. Auto tune in alt-hold mode. It banked right 20 degr., Left 20 degr. and then 70 degr right wich resulted in the crash…
Any thoughts on the matter would by highly appreciated.
@R-thur,
Providing tlogs and/or data flash logs will tremendously help in troubleshooting your issue.

What firmware version are you running by chance? 3.1.3? Or?
Yes, Latest firmware 3.1.3.
As far as I could research myself I think I had an out of sync ESC as I was using SimonK ESC’s. I am rebuilding my tricopter with Non-SimonK’s…
