the PBY's wingspan is approx 36"
its scale is approx 1/28th
it is Guillow kit # 2004
the balsa sheeting I used is 1/32" thick and comes in sheets that are 1/32" x 3" x 36"
and 1/32" x 4" x 36" and wetting it allows it to conform to the compound curves but you have to pay attention to the grain - all wood will bend across the grain better than it will bend in the same direction as the grain...wetting it helps get a tighter radius regardless.
I built it using the kit components for the most part (aside from the sheeting and covering materials)
I would have bought a couple of scale radial engines, and modeled the aft interior where the blisters are if I had decided to go crazy, but I was already over my spending limit and figured preserving my fragile sanity was more important, at least for now.
the film I used is Monokote and is applied with heat...a small electric iron is produced and used to apply it
the model took about a month of relatively steady work..a few hours per day - it was the largest and most involved model aircraft I have done to date. Only the few all wood sailing ship models I have built took longer or were harder than the PBY
