It wasn't the trim that was the problem, the stick was so far back that it wouldn't be possible to tri, it out!
BUT, Yurgon, you were right on the money my friend, Force Feedback in the MISC section of the settings was ticked, removed it and I now have a flyable A-10C II!
Thanks for all the help fellas, it's really appreciated!
I was seriously hoping it was something minor, especially after having to remortage the house to buy this stick and throttle setup! 8o)
