Thanks Luft! I'm glad you, Dudley, Butzell, and R.Recon had a good time!
Here's my process for self-gunning if it helps:
1) I have a button mapped on my joystick that toggles "switch combat post" or something like that. Pressing it once will take me to the nearest gunner position. Pressing it again will take me to the next, and so on until it takes me back to the cockpit.
2) Before taking off (or just after) I cycle through all my gunner positions. At each one, I hit "T" for "take control" and "R" for "reload." That way, whenever I switch to take control of a gun, it'll be locked, loaded, and able to be controlled immediately.
3) The basic key combo for "nestle to gunsight" is "Shift + T" I believe. However, that was simply a pain to hit every time I took control of a gun. So, I remapped it to the "Y" key. I don't think it has any use in the game and it is conveniently right next to the "T" for "take control" key. So, whenever I need to gun, I hit my joystick button, press the "Y" key, and I am nestled to gunsight and ready to shoot very quickly.
4) Flying while gunning: I use my feet on the rudder pedals to make minor adjustments while shooting. Also, I rest my left hand on the joystick and use minor movements to keep my plane steady. I try not to do really spicy maneuvers while gunning, so that I can aim better. However, if both my clips run out, then I shake things up by suddenly snap rolling my plane or something like that. By the time the surprised bandit is able to reposition on me, usually my guns have reloaded and I can go at him again. Number one rule: If you think you are in danger of crashing GET OUT OF THE TURRET AND GET BACK IN THE COCKPIT TO FLY THE PLANE!!! There is no good way to really fly the plane from a turret while gunning. While in the gunner's seat, the best you can do is sort of "guide" your plane like I described above. Fly from the cockpit to get a good position, and then switch to the gunner to take the shots you've opened up. Rinse and repeat until somebody's dead.
