KEIL KRAFT CHIEF
Designed by Bill Dean and originally kitted in 1950, the Keil Kraft Chief was advertised as an A2 contest glider featuring "crash proof" plug-in wings.
Here's what Keil Kraft said back in 1950:
"The Chief is an advanced contest design to the A-2 Nordic specification. Good looks combined with outstanding performance were the main object in mind when the model began to take shape on the drawing board. Three features which were felt to be essential were as follows:
Plug-in wings, for ease of transport, "knock-off-ability" in crashes and good lines.
An auto rudder, to ensure that whilst the model went up straight on the line, a turning flight would result when it was released.
A safe, reliable and easy to build dethermaliser.
These features are all to be found on the model, together with the structural strength necessary to stand up to the strains of towing up in all weathers."
Anecdotes from fliers down the years have shown, that in many cases, the crash proof wings were actually more hindrance than help and received wisdom suggests that a redesign of the wing mount arrangement is well worth the effort.
We supply the kit as originally designed, but a quick trawl of the online forums should yield advice for better layouts.
This kit is a laser-cut replica of the original Keil Kraft Chief.
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 copy of the original plan that is printed on high quality paper at full size.
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.
