Uncommanded pitch up in FBWA

ArduPlane
1

I have experienced something strange, upon applying 75% throttle on my AR Wing in FBWA mode I got a pitch up to around 80 degrees followed by stall and crash. I went trough the log and cant find the reason behind it. I had my elevator stick almost centered yet plane went up to 80 degrees pitch.

Could anyone go trough last few seconds of the log before the crash to find the issue?Log file

You just have a bad tune. Looks like it pitch up and you cut the throttle then it stalled and didn’t have time to recover.

Double check your CG and control throws.
