Hi folks
I fly since early this year a homemade X8 Coax. The multicopter flies very well, but I have a strange problem since the last firmware updates... But I can't tell you when the problem occurs the first time.
I had also the problem between switching from stabilize to althold with altitude loss. Since updating to RC 3.2.1 the problem is gone. But the second one is still there. And it's the following: If the multicopter goes from approximately 40km/h fly speed to hovering in alt hold, the multicopter rears back massively. One time the crash wasn't far away...
As you can see on the data log, there is a problem between Des. Pitch and Pitch.
I'm asking me if this can be a aerodynamics problem of the X8 Coax setup..
Here is the log:

I hope somebody can help me.
Thanks a lot
Michael
