Well, Il-2 wasn't that great at destroying hard targets, thats why I mentioned other planes. You can take image of an aircraft, create second aircraft with the same image, and tweak stats.Kerensky wrote:Thus they need a unit similar to the Stuka G, or similar to a Hurricane IID. Low SA, high HA.
There's little use in having an IL2, IL2m3, and IL10 if all of them have practically identical stats. The game should use the opportunity to have multiple relevant russian tactical bombers. Some are durable, some have better SA, others have better HA. No one unit is 'the best', each has its own a unique role and strengths.
Almost all Allied units are significantly cheaper than German equivalents, for example the Firefly, Comet, M26 are all quite good, but fairly cheap at 300-400 a piece. Allied equipment prices need to raise like we've seen with German equipment. Maybe not to quite the same level, but it needs to be higher than it currently is.
Not much harm will be done, since there are worse things already in the game (I will mention Mustang and Jug again

Another thing: compare Ju-87 to Il-2. Russian machines have the same - if not the better SA / HA stats already (this is not even funny

If you want to create more differences between those versions of Il-2 and you do not want any other types of equipment, here are my general hints:
Il-2: initial version; plane has pretty low initiative; low or 0 passive AA; plane is resistant to ground attacks, but not to fighters (wooden tail, part of wings construction); average SA and low HA;
Il-2M3: increased passive AA; average SA and average HA (lets say that PTAB bombs can make HA increase by 2-3);
Il-10: increased AD, GD (revision of construction, removal of wooden parts); maybe increase Initiative and increase Speed;
