Siesta. All-sheet towline glider to A1 specification.
Quote: "FOR THE YOUNGER modeller the A1 glider provides a stepping-stone from the elementary kit model to the contest A2. Whilst an A1 does not embody the advanced ideas current in A2 gliders, it does step well ahead of the many kit models available and is well capable of putting up flights in excess of two minutes from a 50-metre line, it is in fact particularly suitable for the young modeller who has little cash to spare, but who wants to get the very best for his money.
In spite of its simplicity and size, the A1 has won great popularity on the Continent where many contests are held each year, not only for the tyro but also for the top glider enthusiasts. It is our experience that when a beginner selects a model he looks for one of two things:
(1) A model with a phenomenal contest record; or
(2) A model which can be built in very little time.
In either case he usually builds the model in too little time, with the result that the finished product is often warped or badly finished. It is therefore my intention to put forward a model which although not coming into the first category is capable of giving a good account of itself. At the same time the major consideration has been to produce a model which can be built almost before the materials have been bought (the actual building time being only five hours).
The model described here is entirely of solid construction making it robust and particularly suitable for the beginner. It can be built for as little as 8s., and takes no more than a Saturday afternoon to complete.
Construction. If a rapid programme of construction is to be followed the wing should be started first. Cut sheet to correct lengths and slightly chamfer both sides so that the leading and trailing edges may be added to form the curved wing section (chamfering is best achieved by using a long sanding block). Having pinned the strips together leave to dry for about one hour.
Attention should now be turned to the fuselage, cut the pod to the shape shown on the plan taking care to make the slot carrying the boom as neatly as possible, next drill end of slot with a 1/8 in diameter hole to take wing retaining dowel, cut slot in front of wing rest and sand smooth, also cut circular hole in nose for weight box. Cut the 3/8 in diameter dowel to length (24 in) and add 1/8 in diameter dowel to each end. Cement 3/8 in diameter dowel into pod making sure that both are perfectly aligned (it is a good plan to pre-cement the slot first, ie allow a coat of cement to dry on before finally fixing).
Stand the fuselage in a vertical position and allow to dry for half an hour, in the meantime cut tailplane and fins to size and sand to streamlined section, also cut out the pod sides and, after adding tow hook, assemble with fuselage..."

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.
