Hi there… 
As above, keep on turning left when adding throttle by deflecting left control surfaces.
This is the first time I have seen doing it. Happens only in leveled flight not in VTOL.
Might be that because of the previous crash.
Bench testing without props didn’t show up anything strange.
Software version 4.1.7 - Orange Cube.
Tilted motor belly sitter.
I do have differential spoilers but it is switch off.
