Just my personal control scheme, I do not know how well it will work for you. But...:
Pitch: Left Thumbstick Y axis
Roll: Left Thumbstick X axis
Yaw: Left/Right triggers
Throttle/Collective: Right and left Bumpers
Eject: Back Button (Important in my opinion, in case you screw up)
Manual Fire: Y Button
Flares: B Button
Fire: A Button
Cycle Weapons: X button
External Camera: Right Thumbstick Button
Next Target: Left Thumbstick Button
Again, this is just my personal scheme. With enough tweaking, you can get the right thumbstick to function as the look. However since I am currently at work, I am running through my scheme by memory and do not remember the full list of controls.
