Throttle on Hotazs X

[great gazoo]

I got my Hotas X.

Everything works except the throttle is offset and I can only get 72% throttle. Tried looking around the menus for a setting to chnage but nothing seems obvious. Tried turning system off/on with throttle exactly in the dead spot. but still nothing. No help on Thrustmaster web site. I do not want to take it apart to adjust any pots unless I absolutely have to. Anyone have this problem.

Any serious help would be appreciated.
