The KK Radian is a very clever, Ernie Webster designed, small control line stunt model for 0.5 - 0.75cc diesels or .049cu.in glow-plug motors, (plan includes a conversion for Cox .049 radial mounted engine).
Has all the features of the big stunt models of the time, with asymmetric wing and coupled flaps and elevators, giving excellent manoeverability.
Construction is very straightforward, with a full set of precision laser-cut parts for accurate building.
A really nice, pretty little model!
Interesting clip showing the Radian from the flyer's eye view.
This kit is a laser-cut replica of the original KK Radian.
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.
This type of traditional building technique and flying requires a degree of patience and skill, but is extremely rewarding.

Balsa wood and ply sheets with precision laser-cut parts
Engine bearers and balsa sheeting
Pair of 1 1/2" streamlined wheels
Piano Wire for undercarriage and lead outs
Cloth hinge material
Please note: The vacuum-formed cowling that was supplied with the original kit is no longer available. We have included a set of laminated balsa parts that, when built up, form a cowl of the correct shape for you to hollow out or use as a mold to make your own plastic cowl.
