Dornier Do-335A-1 - 474mph @21,325 ft. 1 30mm/2 MG
This a/c is so damned ugly it has to be modeled!
Kyushu J7W1 Shinden - 466mph @28,545 4 30mm
These aircraft are "different" and with their performance they may actually be competitive in the MA rather than some of the other "novelty" a/c.
POP QUIZ: To my knowledge the Shinden has been modeled in at least one other flight sim. Name one.
