Somebody pulled out a lot of specs and compared them side by side... top speed, power loading, weight loading, wing area, horsepower, the plane stacks up very well against a P-38. The P-38 surely is no spitfire, but it's also not totally dogmeat.
A 410 (if modeled in-game) would be an interesting addition. No, not an uber plane, but stilll... very interesting multi-cannon setups (2x20mm, 4x20mm, 6x20mm, 8x20mm, 2x20mm+2x30mm, more). It wouldn't be very useful in scenarios, or FSOs, but it would be a great all-round MA plane.
