Kestrel (oz806)

About this Plan

Kestrel. Unorthodox twin rubber sport model.

Quote: "In the design of the Kestrel, originality with simplicity of construction have been brought together to produce a twin motor model of the semi-scale type, with a modern fighter appearance. While obviously not intended for duration flying, the model's high speed flights of from 20 to 30 seconds are due reward for those who build the Kestrel.

Fuselage Units. Substitute is employed throughout. The two fuselage units are built up on the keel principle, and care should be taken to get them true. Special attention should be paid to the wing mounting platforms. Form the blocks with their inset paper tubes for the plug-in undercarriage legs, and cement firmly to former number 4 and to keel. Construct cylinders as indicated and cement in position. Build up nose pieces, and drill accurately for shafts.

Bush the nose pieces, with aluminum tubing. The nose piece spigots should be a good push fit into the front of the fuselage units. Small rubber bands further secure the nose pieces and propeller assemblies in position. Add built-up radiators and rear rubber anchorages.

Main-plane. Build in two halves, with ribs at correct angles. Cement halves together, dihedral angle being automatically formed. From centre ribs to centre of fuselage units, leading and trailing edges are planked for rigidity. Type A ribs are to be noted; When the wing has been completed, the tabs on these ribs are fitted into the slots on the wing mounting platforms, and the wing firmly cemented to the fuselage units Add cannon fairing and two 20 mm. cannons.

Cabin, Cupola, Tail-plane and Fin. The cupola is built in exactly the same way as the fuselage units, and when completed the main spars of the tail-plane are cemented in position, before the leading and trailing edges are added.

Finally the tips, which have been steam-bent, are cemented and bound in position. The locking pieces on the main spars are to be noticed. The top and bottom of the fin are built on the plan, and cemented squarely in place. Cement completed tail assembly firmly to the rear of the fuselage units, checking for accuracy and seeing that the tail-plane is set at 0 degrees incidence..."
