SCOTT AND BLACK'S COMET

SOLID MODEL OF WINNING 'PLANE As I thought would happen I have already had numerous inquiries for the plans of the de Havilland Comet, and as promised last week I am pleased to be able 'to supply the information required. Will my readers who have written in asking for information and plans please take this as an answer, for it is certainly much more detailed than I could give each of you personally. In the sketch herewith, the correct markings are shown for Messrs. Scott and Black's machine, the fuselage and wings being all red, with a white line. The- markings should be done in Indian ink. If you work off these plans, you can decide the actual size of the model you aro going to make- yourself, but if you get a kitset, containing all the necessary parts and pieces, you will find in it a plan full size and drawn to exactly 1-OOth full size of the real machine. This gives a wingspan of nine inches, a handy size for most purposes. Having cut your wood

to the square of the sizes required, i.e., the fuselage piece will be Gin by Jin by Jin, turn the block over on its side and mark off the side elevation shape of the model. With knif,e or fretsaw cut out to this shape. Now repeat the process, only marking from the top view. By carefully watching the shapes of the various sections you can now shape up tlio fuselage with a sharp knife or razor blade, arid then first with rough and later with fine glasspapcr smooth away all roughnesses. Finish the fuselage

by giving it a good coat of brilliant rod dope, smooth off with glasspapcr and paint it again. It is now ready for markings to be put on. These can bo done now or later on just as you desire. The wing is cut out, the broadening effect near the wing roots, where tlio wing joins the fuselage, being obtained by cementing on extra three-cornerod pieces of balsa. Sand off and dope it red. Each separate part is thus formed, smoothed and painted. Do not make the mistake of trying to assemble the model first, and finishing and doping afterwards, for you will not be able to get in the corners and get that high glossy finish which is so necessary. The propeller blades aro liny pieces of aluminium, cut to shape and stuck into the propeller noses. If you want the props to turn, you will make the propeller spinners separately and give the aluminium blade a twist. See that the propellers revolve in opposite directions. Assemble fne machine, using Balsa cement, and if you have to, tiny pins can bo inserted, but do not use too many, for you leave a hole in the covering dope where they are pulled out and this has to be patched up. The Undercarriage.—lf you are goinj to harig your model in a flying position, leave the undercarriage off. In other words build your Comet with the wheels retracted, it being quite correct, and

gives a neater finish. Use Indian ink for marking in the ailerons, rudder and elevators, and the black lettering, silver for the windows, with black outlines. In the- kitset I have had prepared, all the balsa parts are cut to the square sliapo, as explained above, and all the necessary materials included for making the model, the only exception being the Indian ink, which every boy can get easily. Send a postal note for 1/6 to Propeller, care of the "Auckland Star," and your kitset of the Comet will be posted right away.
