Where do you start with IL-2 1946?

[Geckomeister]

Hi,

I am new to the game...so have more questions than fun with it right now.

I have IL-2 1946 4.11M...it has a crap load of campaigns...single missions.
Training is all video's, rather than interactive, so where do I start?
Is there a campaign for beginners?

All I seem to do is crash on take off or if I do manage to take off spin uncontrollably til I crash in the middle of combat.
So I guess its safe to say I have mastered the crashing part of the game!
I dont seem to be able to catch up to bombers (in the RAF @ Singapore mission) so not sure if I am doing something wrong there.
What do radiators do? Does it get rid of the "Engine Overheating" messages?

Any sort of explanation would be great.

Cheers
Gecks
