X-55 Pitch axis problem

My X-55 is calibrated in Windows and works fine in other sims. However in DCS when the joystick is centred, DCS sees it as thought I am pulling back. When I start a mission airborne, the plane is pulling up. Ordinarily, I'd put this down to a calibration issue or a key binding problem, but I've checked these. See pic below of ingame axis when joystick centred.

Disabling Force Feedback fixed this :)
