Note that kit is of the R-2800 powered PBM-5A amphibian, which was post-WWII and only built/used in
small numbers. The kit includes gear-well blanking plates so with a little work it can be built as a
PBM-5 flying boat, however, no beaching gear in the kit. Building the most common WWII type,
PBM-3, requires different engines, and the earlier dash numbers require smaller nacelles. Evidently
the biggest shape error is a too shallow rear fuselage, which, according to a couple of commentators, Rareplanes got right.
US list of $69.95 is steep, but it less than the price of the Mach 2 kit, and unlike the Mach 2 kit
the Minicraft kit is a typical modern, mainstream injection moulded kit. So at the end of the day
I guess it's a matter of how much your time is worth.
