O.K....a clue...or two...more...
Good guess, but not the Do-335...
1) Twin engines...
2) monoplane...
3) Conventional layout, as we have come to know most designs...yet...
4) Quite un-conventional, when we think of a twin engined aircraft...
5) First flight was several years before the Do-335...
6) Intended as a fast, light bomber and recon aircraft...
7) It was an ambitious, and parhaps overly complicated design, which is is possably why only a couple of prototypes were made...
8) Although performance was quite good, it lost out to design(s) more favorable to mass production...
9) Liquid cooled engines...V-12's
10) An unusually large number of, for the time...(two and a half dozen) electric motors / actuators were used to drive the ancillaries...these are some of the complications I have mentioned above...(landing gear, flaps, cowl flaps, etc.)
11) Main landing gear rotated 90 degrees to fit flat / flush w/ under side of wing...
12) Crew of 2
13) First prototype was test flown with only one engine...
14) and...had skis (at least temporarily) fitted...
15) Had a small Bomb Bay ("emergency...come right away."..sorry...stupid "Bewitched" joke there...) in between the Pilot and GIB...(Guy In Back)
16) First version Empennage very similar to the Stuka V1's...twin fin/rudders...to give better field of fire to the GIB...
