I fly the IL-2 a lot and I love when a enemy con is engaged with 1 or 2 friendlies. I'm almost always able to, if not get a poke on him, at least throw him off his game so my guys can get him.
1 on 1 against a spit I go right to the deck until the grass is hitting the IL-2s belly. I try and get the fighter flat and force an overshoot, then hit him with the big guns as hes trying to get away. The good sticks wont flatten against an IL-2. They fight you in the vertical and then you have a big problem. Either way I never quit or run.
Lynx would be the last guy I'd want to IL-2 against a spit with. But I dont believe in passive fighting which is probably why my scores arent that good.
