Fairchild FB-3 NX7385Fairchild's first flying boat (there doesn't seem to be an FB-1 or 2). Only one built, 1929. Four place all metal monoplane powered by one pusher Pratt & Whitney R-1340 Wasp, then only producing 410hp. Wings and tail were fabric covered metal structures, hull was aluminum clad. Span 52', length 41 feet, top speed 130mph.

* Strictly speaking it's an amphibian.
