About this Plan

AW-6-A. High wing rubber duration model. Uses a geared reduction drive.

Quote: "THE design of this model has been carried out on quite realistic lines, and some original features have been introduced in its construction. A compressible-strut undercarriage, hinged tail-plane, and hooks which have been made easily accessible, have all proved very efficient and well worth the extra time taken in constructing them.

The calculated air speed of the aircraft is in the region of 15 mph. It has therefore necessitated construction to be carried out on robust lines, and it can be stated here with satisfaction that it has withstood the wear and tear remarkably well.

Experiments have shown that by using a slightly larger propeller (ie. 18 in diameter, 24 in pitch) to that shown in the photographs, better flights were obtained. This necessitated 83 per cent more rubber, and thus increased the wing loading, which is now about 6 oz per square foot, the total weight being 9 oz.

Fuselage. Fig 1 shows the side elevation and projected half-formers. A jig, which can be recommended for a fuselage of this type, was used. After the formers have been cut out of 1/16 in thick sheet balsa, and strengthened actress the top and bottoms, cut out of stiff card, pieces to correspond with the inside shape of the formers. Attach these temporarily with four small slips of paper (see Fig 8).

Next procure a perfectly straight stick of hardwood about 3 ft long and 3/8 in square. Mark out on the cardboard centres, now firmly glued in place, in. squares in their respective positions. With a razor blade, or better still a 3/8 in chisel, carefully cut out the holes and thread them on the stick, and proceed to set up in the correct positions, glueing them firmly on. The jig should be held firmly in a vice whilst attaching and cementing the longerons in position.

When thoroughly dry, cut away the cardboard centres and extract the stick. Trim off the ends and cement rear block in position. Fig 4 shows this, also the swing out hooks, which enable the rubbers to be easily hooked and unhooked..."

Notes

* 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.

Scaling

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.
