[slipper]

I have just downloaded compans excellent new campaign at mission4today, in it he substitutes a Spitfire MKV for a Spitfire MKII, as the action takes place towards the end of the Battle Of Britain into 1941. I know we can substitute the MkI into the game, but i was wondering if the MKI FM could be modified fairly easy to add a MkII, as a new plane? would this be a fairly easy mod?
