I tried the replacement combatstick again this weekend. Mashed up the trim wheels and opened up the control manager (didn't remember using it all with my old combatstick) to make sure they were centred properly instead of feeling for the middle notch.
Then calibrated with that outside of game.
Had to re-assign all my buttons as the game had all my CH devices in lower case when they are normally in capitals (don't know what that is about)
Anyway it now works as intended so I take it all back CH still rocks!
Look out because I don't have a handicap now.
