Hello! Since my last firmware-update my roll-axis is acting very strange: If I change the direction of the gimbal (for example: from north to west) the roll-axis moves several degrees (about 20 degrees to the left if I turn 90 degrees from north to west; -20 degrees to the right if I turn 90 degrees from north to east). This happens everytime: In a building, on the field far away from magnetic disturbances, with quadrokopter in 200 m above ground, on the eath without quadrokopter,... I use the 8bit-Board with 2 axes. Can anyone help me?
