Is acro really acro?

I’m flying a pixracer cibios with 3.6.9 for quite a while and simple acro works. There is some kind of difference between pitch and roll flips. Roll looks better than pitch. So I tried 2 rolls in a row. See the surprise:

after one and a half it stopped rotating even the roll stick was still completely at the end. I pushed the throttle to give it more power but it was dizzy so I couldn’t get back control :roll_eyes:
Any idea?
See the isuue starting at 18:36:08,5 were Roll diverts from rollDesired…
