【轻木航模飞机图纸】voyager by EARL STAHL This scale job has CO2 power -- you spend your time flying, not fussing Among the fastest selling planes of the day are the well known Stinson Voyager and Flying Station Wagon. Reasons for this extreme popularity are numerous. Of all the larger personal planes they are among the least expensive to purchase and operate. Further, they can be flown with ease. But probably the most important is their wide usefulness. With the ability to carry 4 passengers in comfort, or a pilot and a sizable quantity of cargo, they serve as family plane of business craft of great utility. As compared with some of its competitors, a Stinson is fairly slow since it cruises at close to 120 mph. Yet this is somewhat offset by the fact that it can be flown by pilots of limited experience into and out of any field that can be called an airport. This is not always possible, of course, for planes of higher stalling speeds and more qualities. In this connection the writer can volunteer the opinion, after flying Voyagers, that just anyone who can fly any other type of plane safely can master the Stinson with ease. Our model is of the latest Stinson which features larger tail surfaces to enhance the plane's inherent stability. The Voyager's configuration lends itself well to the requirements of a good model, particularly one powered by an expansion-type reciprocating engine such as this one has. We used one of the Herkimer OK CO2 engines in the test ship and were highly pleased with the results. Light weight, so long as it is consistent with strength requirements, is always important whether it be in the creation of a giant transport or bomber, or a mere model, and our Voyager is no exception. Since the carbon Dioxide capsule and motor unit weigh considerable, the airframe must be fabricated with extreme care to keep the gross weight close to 5 oz. Construction of the model is really quite simple and no difficulty should be experienced if drawings are studied and the text read before starting. Balsa wood is used throughout and regular model airplane cement is the adhesive. You will want a model that is a treat to behold whether it is on the shelf or on the wing, so assure this by putting your best effort into the task. Since assembly of most parts can be accomplished more easily over full size drawings, the magazine page layout should be doubled. This is accomplished by stepping off each dimension twice using dividers. One-half inch grid is imposed over many of the curved parts to ease the job of enlarging them.
