OK, try this.
Load the game and select "offline practice"
On the clipboard goto "preferences/flight"
Check the boxes in the second column that say "Pitch ladder" and Control Pos" and click OK to save it.
Jump in a plane, before you take off select "preferences/UI". This will put a box around everything on the screen you can move. Move the Control Pos box to an area you can easily keep an eye on it. Click ok when your done.
Launch and get your speed up and do the moves that are giving you trouble. Using the control position box you should be able to see all stick and rudder movements to help determine what is giving you trouble.
Give it a try and lets us know what you find. You could also film the test and post that here for the guys to check it out and maybe spot something your missing.
Good Luck!
