You know, that CANT Z.511 is actually quite an attractive aircraft... sort of like an Fw 200 on floats. Certainly the nicest looking Italian airplane I'VE ever seen.
Anyway, on to the question. An interesting one for ya:
This aircraft was developed as a fast bomber, the first prototype being built the same year WWII started. It was similar to the later Do 335 in the fact both aircraft attempted to solve the same problem- how to get the power of twin engines into the low-drag airframe of a single-engined fighter. The solution used by both was also similar (but NOT identical!).
The first prototype was only fitted with one engine initally and was mounted on skis (a clue as to the country of origin). It was found to be sluggish with high wing loading due to the small wings used in proportion to the fuselage. The second engine was eventually fitted, and despite good high-speed performace, landing and takeoff was found to be unsatisfactory due to both wing problems and nose-heaviness.
A second prototype was built, this one inexplicably built with SMALLER wings than the first. While several planned verisions were put forward, the entire project was scrapped.
A few more interesting notes:
- The plane had no official designation, although it is most commonly referred by its designer's name and a single letter. This is the one needed for a correct answer.
- The designer went on to lead the design team for one of the particular country's first "almost operational" rocket fighters.
- Resin kits of this aircraft exist made by three different companies- the oldest by a small cottage industry, the second by a Czech company, and the latest by a very well-known larger resin company. The last is currently in the latest Squadron catalouge.
Enough info? Well, I'm done.
Have fun...
