KEIL KRAFT ELF
The KK Elf is a very pretty, small rubber-powered cabin duration model, with traditional, simple, built-up construction and would make a very good first flying model.
Fine flying performance and can easily be converted by the more experienced to take lightweight electric motor and 3 channel R/C equipment for indoor or calm outdoor flying.
This kit is a laser-cut replica of the original Keil Kraft Elf.
Construction of the model from this kit uses the traditional method of "stick and tissue", that consists of a built up balsa wood skeleton (framework), covered with a tissue skin.
The balsa frameworks are built over a plan that is printed at the exact scale of the model, which is in essence a real engineering drawing.
Power is provided by rubber strip motor that is wound up before flight. Free flight means just that - once the model is launched, it is on its own. It must follow a predetermined flight path established when the model is initially adjusted for flight or "trimmed".
This type of traditional building technique and flying requires a degree of patience and skill, but is extremely rewarding.
