I built a fun model of what may have been if DeHavilland Canada had cut metal for the prototype Beaver in February 1947. At this stage the design was still built around a 330hp DeHavilland Gypsy Queen engine, a little known fact is that the Beaver's very strong STOL characteristics were incorporated because of the low anticipated power output of this engine. As history panned out though, the 330hp Queen engine blew up on the test stand and DHC turned to the trusty P&W Wasp Junior & the rest is history. The DH Gypsy Queen however went on to produce up to 400hp in later Dove models.
The model is based on the Airfix Beaver with Gypsy Queen engine from a Heller Rapide kit It actually looks like quite a nice aircraft, however it would not have had the rugged versatility of the final Beaver design
