Cc3d stability problem

Hello,
I need help with my new quadcopter stability

Hi
Is the cc3d mounted in “normal” orientation ?
- arrow facing up and forward ?
(And is it mounted firmly ?)
Is this cc3d using librepilot or cleanflight?

Hi,
Yes the cc3d is mounted in normal orientation, arrow facing up & forward.
I’m using libre pilot.

It does seem to be trying to stabilise.
Check props on correct way up.
Did you use the set up wizard ?
Are you using attitude or rate flight mode ?
Is 'zero integral at low throttle ’ ticked and saved ?
Are you using default pids , and response rates ?
Are giving any input apart from throttle ?
Meanwhile no harm in re doing level calibration on attitude page , ( and check orientation is 0,0,0 on that page )
