Looks ok, probably better for most missions than the twin-Pulqui. I think I'd add more frontal armament as well, 1x20mm + 2x13mm isn't that much. Where is the tail 7.62mm MG? Do you mean in the ventral hatch instead?

Weight will increase quite a bit over the Pe-2 when you add in V-1500S engines, might need to extend the tail for balance.

To be honest, I'm not entirely certain what it means. I pretty much copied the Pe-3Bis specs and that was the listed armament.

What about putting 2x20mm + 2x13mm in the nose, and a 13mm MG in the ventral hatch?

Based specs off the Pe-3Bis rather than the Pe-2, but it brings up a good point. The Pe-3 was derived from a bomber, so perhaps I should prepare specs for a bomber variant.

Change log:
- Tail extended by 3 feet for balance.
- Weights increased to account for larger engines

Also: apparently the Russians tried the Pe-2 as a fighter using a nose armament of 2x20mm + 2x12.7mm + 2x7.62mm. So I'm thinking 2x20mm + 2x13mm should work for the Caracara-A.

Change log for Pe-2 --> Caracara-B:
- Klimov 1,210hp V12s changed to Spartan-1300
- MGs altered to Chilean specs.

The Pe-2 specs state 360mph with 2x1,210 hp Klimovs, so I'm wondering if the 1,500hp Spartans can do even better than the 365mph I had guessed at. Maybe 375mph?
