Hornets Nest Help

[Red Dog XII]

First Time Poster here! Just got the game today and got snagged on Hornets nest. The IL-2 is not the best at knocking down hoards of JU-52's. The best I have done is 4 left before they reach their destination. Any tips or assistance would be greatly appreciated from u guys. Let me know if I am missing something. I have been reading these posts for a while now and it seems there is quite a few knowledable people here so I thought this would be a great place to ask for some help. Thanks again for any help u can give me!
