Swanson-Fahlin SF-2 / Fahlin Plymocoupe

TerryLeave a comment

Designed by Swen Swanson and Ole Fahlin, the 1935 Swanson-Fahlin SF-2 was a two-place cabin, high wing monoplane, registered N365 c/n SF-2.

Powered by a Plymouth PJ auto engine (not inverted as often thought) with a geared propshaft, it became known as Fahlin after Swanson’s death from pneumonia in Feb 1935 during construction.

Sold in Novrmber 1935 after it failed to meet DoC contract specifications and, fitted with extra fuel tanks as Sea-Aska, it crash-landed in fog at Juneau AK in September 1936 during an attempted non-stop Anchorage-Seattle flight—pilot Russell Owens telegraphed his backers: “Sea-Aska on her asska in Alaska.”

Destroyed in a 1938 hangar fire in Juneau.

Although Plymocoupe is often thought to be an Nicholas-Beazley product, none was ever produced by that company. Fahlin went on to fame and fortune with his propeller business.

Swanson-Fahlin SF-1

Swanson-Fahlin SF-1 NX271Y

Based on Swanson W-15 design, the 1934 Swanson-Fahlin SF-1 was a two-place cabin, high-wing monoplane, powered by an 85hp Pobjoy R engine. It first flew in April 1934, registered NX271Y c/n 1.

It was repowered c.1937 with an 85hp Continental A-85.

Disposition after c.1940 is uncertain, reportedly was stored in a hangar on a field taken over by the military, who consigned it to the scrap pile. Despite many references to a trio of Swanson and Fahlin-designed planes built by Nicholas-Beazley Co, only the SF-1 and SF-2 were built at the N-B plant, and those by Swen Swanson in rented space.

Engine: 85hp Pobjoy R
Wingspan: 28’0″
Length: 21’10”
Useful load: 500 lb
Max speed: 130 mph
