[RESOLVED] Need help with quadcopter X8 coaxial tuning

Hi,
I just took my quad to a second flight, yesterday was the first time after a big re-construction and there seems to be some issue with it’s stability.
It seems like it is twitching a lot and it give the sense like it about to flip.
Any input would be appreciated.

Motors were not leveled, so it seems.
