Pretty much double the size, from current PBY to Flymodel PBY, Boats My Friend.
Though it will look good as a kind of "forced perspective" display, one hanging about 4 ft from the other would look as though they were flying in company but a couple miles apart.
I'm very much looking forward to seeing this magnificent PBY completed. The detail in the landing gear, and the beautifully done wing construction are both elements I much admire.
Kind and Respectful Regards Boats My Friend, Uyraell.
