Addman,

Just one interesting point, I have noticed that in every checkilst, the items and their order matters for safety thought you may not notice at once.
You will benefit from adjusting the elevator trim (not only at take off but all flight phases) as the controls feature a non linear joystick curve, thus smooth and more accurate controls around the center position.
So if possible I would recommend to set an available spare axis for elevator trim so as to keep the plane in a natural equilibrum for the main flight phases.
It helps in a dogfight too, the possibility to set elevator tab to something close from your actuall speed and attitude so the aircraft is more stable and more accurate to control.

Spitfire is sensitive to the right distance for firing a taget as your guns cross at a predefined distance. You can both adjust this distance in the gun menu before flying and set your gunsight distance and ennemy aircraft wingspan.
This is explained more in details in other places.

In aircraft world, procedures are designed to affect many other areas, they are not just meant for a single purpose.
