a tip for the la7 cannons
 

I've found in realistic that the twin cannons are most effective when used against the wings of enemy aircraft; dealing them lethal damage in one hit and blowing the wing clean off in two.
To go with the thread i too share a love hate relationship with the la7... it seems to handle damage better than any other aircraft in the game.
I do quite often feel guilty when using it in a dogfight
