Help with the first single mission in Battle of Britain

[Bobby D]

Hi guys. I am new to flight sims, and while I have been reading up on all sorts of books about flying and how planes work, there are still many things that I don't know. I have completed the campaign on Realistic difficulty and can control my plane now without putting it into a spin every few seconds.

Anyway, I started playing the first single mission, also on Realistic, and I just can't shoot the enemy fighters down fast enough. Is there any trick to being able to take them down? Or do I just need to get better at aiming/shooting?

I have skipped this mission and gone on to complete most of the other other single missions in the Battle of Britain, however this one is still giving me trouble.

Thanks for any help!
