Hi Don,
there's some good advice given (but may not be entirely suitable to your circumstances- i'd say the desastersoft demo may be a bit much at first, it's rather good and i recommend it highly- but maybe when you feel happy with the basics
)
I've made a little collection of some very basic missions, mainly using the Hurri tho there is a 109 flight as well.
briefings are sparse as they were for private use but should be fairly self explanatory. :-
Hurri1 for takeoff, landings, general flying around.
Hurri2 to learn staying in formation
Nav2(airstart) is flying a triangular nav course (get you used to the RAF compass)
then there are 3 'combat' missions
12v12(airstart) pits you against 12 very nasty 109's
501 is a convoy patrol
32 is 'pretty full on'- ~100 a/c. this is a wip of something i'm working on.
I'd suggest you get to be able to fly the first 3 before diving into a campaign, but how you choose to progress is entirely your choice
