In the kit business since 1986, Diels Engineering, Inc. manufactures and sells free-flight, rubber-band powered model airplane kits (both complete kits and short kits), plans, and related accessories. We specialize in high-quality, craftsman-type model kits of military aircraft (with a few exceptions) from various nations. The current product line contains a selection of well-known and less well-known types primarily from the 1920-1950 period, many of which are not available in kit form from any other source. Most kits are designed to 1/24 (1/2" = 1') scale . We also have a few peanut scale (13" wingspan maximum)kits and a line of peanut scale plans.
