Outerzone’s engine category is a catalog of free plans and blueprints for building model aero engines. The search returns 45 designs across two pages; the displayed first page contains 24 entries, each identified by its name and plan number, with details such as designer or publisher, date, engine capacity, and engine type. The listing spans small and large engines, from a 0.015-cubic-inch diesel to a 14.3 cc spark engine, and includes diesel, glow, spark, and combination-type designs.
The plans range from historical designs, including the 1937 Chunn Chum and 1939 Belmont G9, to recent projects such as the 2022 Holly Buddy Twin. Notable entries include the 0.5 cc Ace diesel from 1947, Chris Boll’s modern BollAero engines, Ed Holly’s 2.5 cc Buddy, and a five-cylinder radial designed by Forest Edwards. Designs are attributed to individual builders and contributors as well as publications such as Aeromodeller, Model Airplane News, and Motor Boys International. Each result links to a plan-details page, making the catalog useful for browsing engine designs by size, ignition type, designer, or period before selecting a blueprint to examine.
