Actually the Soviets weren't savvy enough to realize how dangerous those two aircraft were to fly, with the mid engine, and driveshaft, a stall/spin was a thrill waiting for the opportunity to happen. Give me a Mustang, Spitfire, Me-109, Hawker Sea Fury, even a Thunderbolt, but please don't give me a P-39 or P-63, they did probably beat freezing to death. Very kool looking aircraft, but that aft CG was BAAAAAD! The Mustang, P-38, Hellcat, Corsair, and Bearcat where all outstanding and fast... billy
