Light Miniature Aircraft LM-1

A three-quarter scale Piper J/3 Cub look-alike by Fred McCallum and Fred Latulip of Opa Locka, Florida. When first shown at Oshkosh in 1983 the all wood design of +5 -4.5G wing was too heavy for the US ultralight category but several years later the construction was altered to aluminium-alloy tube to overcome this problem. Power comes from a 28hp Rotax 277 engine.

All of the Light Miniature Aircraft Manuals, are approximately 200 pages. Each manual has step-by-step instructions, for each section of the plane, as well as figures, drawings and full size templates to guide the builder through the building process. Each manual also comes with a complete set of full size plans for the fuselage and tail feathers as well as full size templates for the wing ribs, landing gear and items such as the wind shield.
The wooden planes are constructed in the same manner.
Plans and manuals are still available for our metal planes, however, due to rising aluminum costs and availability problems, Light Miniature Aircraft no longer supply kits for the air frames of the metal planes. Some partial kits, for items like the controls or landing gear were available.
