Well I was actually having trouble trying to assign them in-game. lol Seems retarded, but it's the truth, not sure why. It just wasn't the normal way of assigning keys, unless I missed something and when I say normal I mean you click the item you want to assign and then hit the button on your controller to assign it. Not to mention I'm just unsure of what controls are important enough to assign to the stick/throttle.
I wouldn't mind checking out your profile for them just to give me a starting point, that would be helpful.
