Not the A6M, Hydro Junkie; but here's a bonus clue to speed your search. Thanks; Ernie P.
What warbird do I describe?
Clues:
1. The genesis of this aircraft was an attempt to follow the research and designs of a noted aerodynamic pioneer.
2. It was designed by another noted, and very successful, aerodynamicist.
3. It set multiple world records when it was introduced.
4. Yet it was actually used for a rather short time.
