Okay, I removed all controls and added them again, it is working as it should now. Thanks for all the help, no idea what the problem was but it's resolved now.
Now to figure out how to trim the damn thing properly (hat switch on thrustmaster warthog) It never wants to settle down even at a constant speed and power setting. In fact I found using the throttle gave better control than trimming in some cases, is this normal or is can the hat switch be set to move the trim wheels much less with every press?
I think I've been flying the F-15 too long...
