I was flying 110's last night on ATAG and killed couple of spits.
I did discover that I could out accelerate a spit in a dive with low fuel tanks. I think fuel weight is a big factor in this plane. I would want to engage a fighter with as little fuel as possible. And as the other guys have said only attack with the E advantage, one or two passes and then run! I was not sure if I could escape but I easily out ran the spits in a dive with empty tanks.
You got so much fire power and ammo and no convergence so you can go for difficult long range snap shots with a chance of hitting em.
Very challenging plane really
