Our short kits contain all the shaped parts that would require much effort to cut by hand. They may be balsa, lite ply, birch ply, or hardwood like spruce. The ribs, fuselage formers, and all the shaped parts are precision laser cut to ensure a quality build. Our short kits have many parts, like ribs, that remain in the sheet, so they are protected. The parts are segregated, sealed in plastic bags, and labeled. A sheet accompanying them has the bag number and the parts in that bag for easy locating. Short kits do not include stock sheet wood or sticks like spars. No metal, rubber, plastic, or fiberglass parts are included. Because of copyright reasons, plans and instructions must be obtained from the designer or their agent.
