G6 - Completely underrated... Very capable when used as a pure dogfighter even in very late war scenarios.
Machi - It's got STYLE. A good burst on a fighter will usually do the trick, but good luck bringing down anything heavier. Slightly difficult to handle, but once you get the feel she is VERY agile. Fast for its time period.
Po-2 - You have to already like the Po-2... But hey, if you like moving slow and launching some rockets at ground targets at tree-top level, than this is your ride.
