Mutant (oz9104)

About this Plan

Mutant. Free flight glider by W. Woodrow, from 'Model Aircraft' January 1956.

Quote: "A lightweight Open Class sailplane by WP Woodrow.

Sailplanes are popular at the RAF Northolt club because many of the members, who are National Servicemen, cannot afford to fly power models. But on the whole they were building their gliders too heavily until I demonstrated by designing the Mutant that strength need not be associated with weight and can be obtained by constructional methods.

Fuselage. Start by cutting K1 from 1/4 in sheet and by binding to it the tow hook. Then cut out formers F1 to F4 and cement in position to K1. All joints must be pre-cemented to give additional strength. Now cut out F5 and F6 and join together by the lengths of 1/4 x 1/8 in. Make up the auto-rudder mechanism as shown and cement in position on the struts joining F5 and F6. Cement the whole assembly to K1. Cut out the fuselage sides from 1/16 in sheet, taking care only to cut the auto-rudder slot in the port side only. Cut F11 from 1/4 in sq. Now cement the sides to F1-F6 and the tail ends to F11.

Cut out the fin from 1/8 in sheet; build up underfin and rudder from two laminations of 1/16 in sheet and sandwich the linen hinge between them. Fit the ply rudder horn to the rudder..."
