Good morning, guys!
Two American training aircraft of WWII, very well known during the war years, but largelly unknown, at least for civilians, in the postwar era: Curtiss Wright AT-9 and Beechcraft AT-10.
Both aircraft were intended for training of bomber and transport aircraft crews, both were motorized with the Lycoming R-680 9-cylinder radial. The construction mainly of wood doomed the postwar life of AT-10, and the tricky handling was considered too dificult for untrained civilians sealed the fate of AT-9, so by differnt reasons both aircraft were not sold to the public after the war and only a couple of both models survived the war in static exhibitions.
Three sporting American aircraft equiped with the Warner Scarab family of radial aeroengines:
The all metal Ryan SCW, very modern for the era, with cantilever wings and enclosed cabin for three.
Aeronca LC was a conventionally built aircraft (welded metal, wood and fabric), but with cantilever wings and enclosed cabin for two seated side by side
And the also of conventional construction, Monocoupe 90, had a braced high wing and was a monoplane with enclosed cabin for two side by side. Equiped with several engines ranging from the 5-cylinder Anzani (60 hp), to the most powerful version with the Warner Super Scarab 145 hp radial, with Lycoming 4-cylinder boxer engine, Franklin 4-cylinder boxer, Kinner, Warner Scarab Junior (5-cylinder), Warner Scarab (7-cylinder) and Lambert R-266 (5-cylinder) radials; all the engines were in the 80-120 hp range (the Lambert engined being the most prevalent model, 90A); in between.
Cheers.
