My I2 was doing some hard braking and I noticed it sitting crooked and not level once it stopped. The gimbal and camera were level on the screen, but the bird was titled sideways by maybe 30 degrees in hover.
I decided to do another IMU cal and I'm not too crazy about the two parts where they have you rest the bird upright on the sides as it wobbles with me holding it and the legs are sort of flimsy in that position and some have reported them being crooked too. The sitting flat, and on the front and rear lower legs are okay and I don't have to hold onto it, but the sides aren't and I think I did the first ones resting on the legs (Which are tilted in a bit and not the motors?) and the screen's demo shows it 90 degrees upright.
So I pulled out some 3"x18" plastic ruler out of the sewing room (Used as a cutting wheel ruler.) and used it as a carpenter's square to make it 90 degrees on the side by holding it against the two legs and the level surface rather than wobble on the side. Maybe an aluminum carpenter's square would also work being non-magnetic although I don't think the compass would be influenced in IMU cal but don't know hence the plastic one.
Need to try a flight again and see if it sits level after hard braking.
