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..."

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
