Lincoln Sport Biplane — Original Construction Plans

Lincoln Sport Biplane — Plans for the Late-1920s American Sport Biplane

The Lincoln Sport Biplane was developed by the Lincoln-Page Aircraft Company in the late 1920s and refined by amateur builders throughout the 1930s. As a single-place open-cockpit sport biplane, the Lincoln Sport occupied a sweet spot between the heavier commercial biplanes of the era and the simpler parasol monoplanes — sportier handling, more spirited performance, and a more conventional biplane configuration that appealed to builders who wanted a “real” biplane experience. This download presents the construction article from the Modern Mechanics and Inventions Flying and Glider Manual series (1930-1932).

A Single-Place Open-Cockpit Biplane With Conventional Layout

The Lincoln Sport Biplane is a single-place open-cockpit biplane with a conventional wood-spar wing structure, welded steel-tube fuselage, and fabric covering. Equal-span upper and lower wings with N-strut interplane bracing give the aircraft its characteristic biplane look. The Lincoln Sport was offered with several engine options — the Anzani 6-cylinder radial, the Lawrence L-series radials, and later the Salmson 9-cylinder radial — each producing 40 to 60 hp and giving the aircraft a respectable cruise speed for its era.

Performance and Specifications

• Configuration: Single-seat open-cockpit biplane
• Engine options: Anzani 6-cylinder, Lawrence, Salmson 9-cylinder radial (40-60 hp)
• Construction: Welded steel tube fuselage, wood wing structure, fabric covering
• Era: Late 1920s to mid-1930s American amateur-built sport aircraft

Who Should Build the Lincoln Sport

This design suits the intermediate-to-advanced builder comfortable with both welded tube fuselage construction and conventional biplane rigging. The Lincoln Sport is a more demanding project than a parasol monoplane — twice the wings, plus interplane struts, flying wires, and the rigging knowledge to set them up correctly — but the resulting aircraft offers a more spirited flying experience and an authentic 1920s sport biplane feel.
