About this Plan
Westland Lysander (Westland A39/34, Westland Cooperation). Rubber scale model. From Model Airplane News, May 1937.

This Westland A39/34 is probably the fastest and the most useful Army Cooperation machine that the British RAF has ever possessed. It is equipped with Handley Page slots and flaps to enable it to get into and out of small fields such as the type of small front-line landing ground encountered during wartime conditions. It carries two-way radio communication; is equipped for picking up messages from the ground while flying and has photography apparatus in addition to carrying a fuel supply great enough for a six hour flight.
The Westland A39/34 as it is temporarily designated, has a span of 50 feet and a length of 30 feet. It is powered at present with a poppet-valve Bristol Mercury en-gine of 600 hp. This engine is being changed in the production A39/34 to a new sleeve-valve Bristol Perseus 825 hp engine. It has an automatic controllable pitch 3-bladed prop. The plane itself is constructed entirely of metal with fabric-covered wings and fuselage. The tail units are covered with light metal alloy sheeting. The cockpits are situated so that the pilot and his gunner have the maximum amount of vision at all times and at the same time are in direct communication with one another. The pilot is seated exceptionally high up in front of the observer. Both cockpits are heated for high altitude flying. The landing gear is of the single strut type and the wheels are covered with a peculiarly-shaped pant.
The flyability of the model is quite good due to the gull-shaped wings and the lightness of the construction. The model as described here has flown for a half a minute but when the 'extras' such as the insignia heavy dope, etc are left off the model and the construction is lightened, then the plane is good for flights of over a minute and is recommended for flying scale model contests. Now let us get to work (or pleasure, I should say) building one of England's premier fighting planes.
Fuselage: The fuselage formers are all cut from a sheet of 1/16 x 2-1/4 balsa. The keel pieces are cut from a sheet of 1/16 sheet balsa likewise. The keel pieces are shown on the plan in heavy print. The stringers are 1/16 sq balsa.
The first thing to do is to cut out the keel pieces and the formers from the sheet balsa and then cement the formers in their proper places on the bot-tom and the two side keel pieces. In this manner the fuselage cannot twist out of shape very readily while the rest of the stringers, 1/16 sq are being applied.
The windows of the plane are covered with non-waterproof cellophane. When the rest of the model has been finished and papered and the water is applied to shrink the paper, the cellophane will also tighten up and give a much neater appearance than if the waterproof variety had been used.
The cowl is made in a manner similar to the fuselage and the dummy engine front on the plans can he cut out as can the instrument board and glued into place. The nose block is made from a piece of hard wood (pine) or hard balsa, and is made removable. The tail plug is also removable and is carved from a balsa block 1-5/8 x 1 x 1 in. The landing gear struts are constructed of thick sheet balsa and slipped into the slot provided for them in former number 2. The pants are built up in the usual manner from 1/8 sheet balsa..."

* 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.
