Both T34 have thinner metal construction for the engine hatch doors behind the turret, 20mm. The IL2 is the easiest platform to take advantage of that fact in a 60-70 degree dive. That gives you the best chance of not being laser guided single skeet shot out of the air while you are hanging in your straight line dive holding rounds on the 20mm engine hatch doors. Your first pass if you hold on target for about 10-20 rounds will smoke the engine.
You can penetrate the doors with the G2 in a single shot dive, but, the pull out from starting your shot at 200-300 is dicey. I have a gunsight that makes single shots easy with the BK 3,7 once you get rid of joystick nose bounce and make your rudder more sensitive to reduce the need for large inputs. G2 dive so slow, I stopped using them against T34 in the game because they are death traps to commander mode gamey shooting BS. In offline testing, starting at 1000 with a single shot, you can smoke the engine or track the T34's. But, in the MA, the time needed to fly straight and setup the aim lets the gamey commander mode kill you just as easily as if the main T34 gun was a destroyer's 5incher. It's also as easy for M3 to kill the pilot as shooting Storchs.
The HurriD, well that's a precision instrument for cracking those engine hatch doors. I use the same gunsight in it. The trick is a 45-60 degree dive at the hatches. Then shoot close and pull out without kissing the tank. I only fire once in each pass because of the induced bounce and loss of targeting. But, it only takes one hit on those doors. Problem again is the gamey commander mode single shot. It's almost as good as the 5incher and it doesn't have the same fuse.
There is a common theme here. As our tank busting planes perform obviously as good at doing that which they did very well in WW2. Hitech gave the tankers a gamey solution that didn't happen in WW2 with WW2 hardware to counter them. I die more often now from not pulling out of steep dives correctly as our master single shot skeet shooters wing me out of the air in our now WW2 tank hunting death traps. The hardware was designed to defeat tanks while flying low and shooting them from 200m-300m in the sides. Not diving on them and maybe pulling out at the last moment knowing penetration is not possible outside of 300m.
