This embryonic Tigercat is a project rather than a whif ...
The Grumman Model 51 began as the unbuilt XP-65 for the USAAF. But the G51 was also entered into a 1940 US Navy competition for a fighter/land attack aircraft for the planned Midway Class battle carriers. The Grumman concept was further developed, emerging as the XF7F-1.
Modeling the G51 would be tricky. Compared with the F7F, the nose is considerably shorter; the shorter rear fuselage is shaped completely differently as is the vertical tail; the nacelles are longer and more conical; the wings are mid-set (and shaped more like those of the XF5F/XP-50); and the canopy is bigger.
I've shown the canopy as a lengthened version of the F7F's one-piece glazing. It is just as likely that the original Model 51 canopy would have looked more like that of the Hellcat.
