They look reasonable.IMU is: [X=0] [Y=0] [Z=-3] (LIPO on top)
GPS is: [X=-6] [Y-6] [Z=-8]
They look reasonable.
Have you checked that your yaw stick is centred in the TX calibration page?
How about trying your GPS mounted behind and directly in line with the IMU. I'm sure it will not make any difference, but that's where I have mine and no yaw issues.
I see you have your Hex in X mode. What setting do you choose in motor mixing page? I see it has Hex rotor I and Hex rotor V. What does I and V stand for?
