31 January 2023: Added a size comparison of the XFL-1 and P-39 empennages.
The Bell XFL-1 Airabonita was a one-off prototype based on Bell's P-39 that competed with the Vought XF4U-1 and the Grumman XF5F-1 following the U.S. Navy's 1938 carrier-based fighter competition.
It looks like it would be a colorful and straightforward conversion of the P-39, kits of which are available in every popular scale from 1/144 to 1/32. In fact, several have been done and documented in articles in modeling magazines. However, most—if not all—fall short of representing the actual XFL-1 configuration. Unfortunately, most of the structure, particularly the canopy, was different in detail from the P-39. Not even the 1/72 XFL-1 kits that are available are accurate, since they have the P-39 wing planform, which was somewhat different in taper and span.
For example, this is what it takes to convert a P-39 wing to an XFL-1 wing:
The empennage (both initial and final) is also very different from the P-39's (the final horizontal stabilizer is about the same size and shape but the elevator itself has significantly more chord).
All this and more is contained in my XFL-1 monograph, available from Steve Ginter:
