Just fan our brow! ► The SE-5 made its appearance in 1916 but did not become fully operational until March 1917 when the first batch was delivered to Xo. 56 Sqdn., on the western front. At first the SE-5 was not too well accepted since most of the experienced combat pilots preferred the maneuver ability of the rotary-engined machine (Camel) whose excessive torque could always be relied upon to quick spin or roll and get out of a tight spot. However, this same Fabric stitching on fuselage, flexible Lewis gun, among true-to- characteristic caused many inexperienced pilots to crash life details visible here.

And she could dive at high speeds keeping up with the deadly Albatros and not break up on recover)'. The model is easy to trim and very realistic in its flight pattern. Careful attention is paid to scale shapes and details. Your model can be built without full scale details if desired, but building materials should be carefully selected in any case.

And that is to bring that wandering free flight down out of a thermal so that it may fly again. Also, in these days of higher flying models and shrinking fly ing fields and flight time limits, it is imperative that the contest modeler use a dethermalizer to insure that he can make the required number of flights without losing his plane in the process. In the past, devices have been em ployed to spin the plane out of a thermal. A sure fire dethermalizer but the speed at which the model strikes the ground sort of prohibits its use. Other devices employed were para chutes, pop-up tails, pop-up wings, pop-apart fuselages, split rudders, and spoilers in the wing. We once read where Jim Walker dethermalized an A J Hornet with a firecracker. It does work. But we don’t recommend it as we feel that there are some problems yet to be worked out. In this article, we will attempt to answer the requests of all those modelers who have written this maga zine for information on dethermalizers. We will discuss how you may install and use the one type of dethermalizer which has emerged as the most popular and most widely used, the pop-up stabilizer dethermalizer. There are many versions of this dethermalizer and we have shown here the ones most used by contest modelers. You can combine the features of any one of them to suit your individual needs. The action of a pop-up stabilizer dethermalizer is explained by the sketches in Fig. 1. It is a pretty sight to see your model follow the action of these sketches and break out of a thermal, which would surely carry it many miles away, and descend quickly Phil Kraft light» fuse on his famous Upstart releases ship for a VTO take-off. Fuse-type de- before he starts the engine, top; and, bottom, thermalizers should always use a "snuffer" tube. to the ground almost at your feet. The model descends rapidly, but not too rapidly so that it would be damaged on landing. The rate of descent is controlled by the angle of the stabilizer in the dethermalized position and also the wing loading of the plane. The Pop It! fellows that added weight to their old FA I gassies to make them meet the new rules will attest to this fact. Some of these ships with the stabs popped by GERALD R.

Flight photo. the ANT-25 did not finally achieve success until 1937, but in the meantime several interesting flights were undertaken. In September 1934 as an initial test of the plane, the famous Russian flier Gromov with crew members Filin and Spirin made a closed-circuit flight reported at 5700 miles, but failed to beat the existing record. Levanevsky, in a 1935 Moscow-San Francisco attempt, had to land in Siberia with an oil leak after a 3730-mile flight. Then, in July 1936, Valeri Chkaiov, Alexander Beliakov, and George Biadukov made a long distance flight over the unexplored regions of the Soviet Arctic along what was termed the Stalin Route. Stalin took a great interest in the develop ment of the ANT-25. He saw in it a symbol of prestige for the growing Soviet aircraft industry, and as a propaganda weapon-should it be success ful—of the “peaceful” Communist expansionist doctrine. The 1936 flight was non-stop from Moscow to the mouth of the Amur River, near Nikolayevsk— On display in the Paris Salon 1936, the huge-winged ANT via Franz Josef Land, (Continued on page 42) was a center of interest.

It is far too powerful, 18 MODEL AIRPLANE NEWS · May, 1959 but you can convert the power into just the right amount of thrust by making a small metal prop to fit behind the regular prop, but bend it into reverse thrust—just enough to cut the total for ward thrust into just what you want. But watch out for your fingers! Now we’ve settled on a radio and an engine. What about the airplane? It should not only be light and maneuver- able, it should also fly very slowly, both for ease of control in a limited space, and to keep damage down when you goof on the controls, which you will. Two factors in wing design help to keep flying speed at a minimum; one is high aspect ratio, the other is high camber. The former has the drawback of reducing maneuverability so a com promise is necessary. But high under- camber has no drawbacks except per haps a bad stall characteristic—and we can live with that. Generous dihedral is required so you can rock the model around in tight turns. To fly at the minimum speed, a high angle of attack is required. This is achieved by using lots of downthrust on the motor together with a pretty high angular difference between the wing and the tail. With this arrange ment, the engine drags the plane through the air at a speed just above the stall speed associated with the high angle of attack. In fact, when the en gine cuts, the plane picks up a little speed! This is because the glide is achieved at a slightly lower angle of attack.

But be sure you plasticize foot circles and pusher prop more friendly well the dope used on that tissue covering. tions, a variation of the “Breezy” bi plane was designed. To keep weight down, a long narrow fuselage seemed logical, with the top wing up on cabane struts. The aspect ratio of the wings was increased, and the result was a long, thin biplane. This model flew fine —but it was too fast! The next design went back to the cabin tvpe fuselage, because of the higher frontal area and bigger drag. I used the same wings and tail, and found a definite improvement. This de sign, with a 33” wing span, weighed in at six ounces, and is still, flying. How ever, it requires an area about 100 feet bv 125 feet for safe maneuvering, and this is still a little large. While flying the little bipe, which Bob Bowen, editor of the Lark news letter, christened the Slo’poke, I had another idea for a design which held promise. In the first place the Slo’poke had the prop out in front, which is a bit of a hazard to people who might be watching. It also had a landing gear, which added weight. How about a new concept—from an old one, of course— with the prop in back and a skid to land on?

If the majority of club members prefer this type of race, there is nothing more to be said. However, the intent of Rat Racing is to give every type of model an equal chance. If the majority of club members prefer to see the laurels passed around, matters can be adjusted within the club. Ground surface, smooth or rough, can be basis of interesting local There is no need for special legislation, classification, or rules variations, shifting emphasis from speed to dependability. discrimination against any type of model. First, there is a popular type of start that is different Make these things one, two, three—that's how simplicity pays off. from the one outlined in the rule book. All models and Team racer type landing gears avoid bouncy landings and take-offs. crew members are located outside the flying circle. With the starting signal, the crew members start motors. Models are then carried in turn to the flying circle and released in the order of the starting of the motors. Lap counts start with the release of the first model. This type of start gives a handicap to the slower but easier to start motor over the hot but cranky motor. It also prevents giving a crew-cut to green crew members who always seem to run in every direction but the right one. Second, take-off and landings should be changed from the smooth surfaced area to a rougher one that favors good take-off and landing characteristics of a model plane. Third, concentration should be made on the longer races with their greater number of required pit stops, take-offs and landings on this rougher terrain. This type of start, rougher terrain, and increased number of pit stops, are great equalizers.

Besides the fun , it makes a w onderful prepara tion for V-control flying. ► Have you ever dreamed of flying one of those super-sleek scale jet jobs? Too much work, too much money, too noisy, you say. Here’s one that can be built in a couple of evenings with a minimum of expense and effort. It looks amazingly realistic and sounds just like its big sister as it whistles past the spectators. The secret of its simplicity is the fact that it is a “whip control” model. The idea is not new, being originated during the war (by Jim Walker) when no motors or rubber were to be had for powering of conventional models. Our model has a fixed elevator, rather than movable, as many whip models have. Though not as maneuverable, it is easier to build and to fly and makes an excellent model for a beginner who is just getting started in the control-line field. The model presented here is the Lockheed F-94C Starfire, which I am sure needs no introduction, so let’s get right down to the construction. The entire ship is built from one Js x 6 x 36” sheet of medium or hard balsa. Trace all the parts onto the sheet and cut them out with a sharp knife or razor blade. Note that the grain on the rudder runs opposite to that of the fuselage and there is a slot left in the center fuselage lamination for the addition of ballast. Cement the three fuselage lami nations, engine air inlets, and rudder together and when dry, sand them to shape as shown in the fuselage cross section.

The wood must be just so and workmanship, she must be on the ball. Notes from a champ. ► No doubt those readers who followed the data in Part I and designed their hand-launched glider went on to build one or two and are, therefore, aware of many of the problems of construction involved in these models. This article will present the methods employed by the author in constructing his gliders. Other modelers use different methods, some of which will also be presented. In most cases these differences are merely a matter of personal preference. Construction of a hand-launched glider is usually begun by laying out the wing and stabilizer planforms on the wood. If the builder desires a shape other than square or tapered, the parabola is probably the easiest to lay out (figure 2.1a). The ellipse is reputedly the ideal plan- form shape but is more difficult to plot (figure 2.1b). Other methods of plotting elliptical planforms can be found in any drafting text book. A free-hand curve will be quite satisfactory if care is taken to match the left and right halves and if the curve is drawn without any bumps or sharp corners. Many modelers make up aluminum, cardboard or plas tic templates for their wing and tail surface outlines when they finally arrive at a suitable design. These allow the wing to be cut out accurately without having to match halves and also help to rule out variations from one model to the next, allowing more accurate evaluation of a design over a series of models. Such templates can be seen in The Hand figure 2.2. It is not necessary to have all the tools shown in figure 2.2 in order to build good gliders, but all of them are very Launched helpful if available. Most builders use a plane to rough shape the wing airfoil, although I prefer to carve it with a knife. The razor, sandpaper block, square and straight edge are very necessary. Another helpful tool is a piece Glider of %" plywood about 12" x 18" with a metal straight edge set along one side for use as a building board. One model er I know' uses a sheet of plate glass for this purpose. It Part Two is important that the board be smooth and flat. Several grades of sandpaper are needed: 2/0 for rough shaping after carving, 6/0 or 8/0 for final shaping and 320 or 400 finishing paper for final finishing and polishing. I prefer to use garnet paper, sand-screen or production paper in stead of common sandpaper; these papers are slightly more expensive but last much longer, clog less and give gen erally better finishes. The plank of w-ood selected for use in the wing should be cut about &" longer than the wing, the leading edge determined (it should be the harder edge if there is one), and the planform traced onto it leaving at each tip. Before cutting the w.ing blank to outline shape, mark the dihedral break lines on the underside of the wing, using the square and the leading edge as a reference edge. Score the lines about 1/32" deep with the razor blade so that the surface may be sandpapered without erasing the lines. The blank is then cut to shape and tapered from root to tip; a straight taper to about one-half the root thickness at the tip is usually about right (see figure 2.3a). Rough sandpaper is best for this job. A line is then drawn on the upper surface of the wing about 1" back from the Tools required in building: work board, knife, razor, a square, leading edge on 4" chord wings (%" on 31*" chord wings straight-edge, sandpaper and block, pencil, brushes, templates. and %" on 3" chord wings).

How good are these foreign sections? Thanks to John Stewart, MAN is able to present this rundown of worthwhile sections. While on duty with the Air Force in Germany, Stewart entered many contests, met and flew with the famous modelers in Europe. Into a well filled notebook went comments, ordinates, direct observa tions. The comments below are keyed to the airfoils shown, beginning at the top left, and working down the three vertical columns. For space reasons, abbreviations sometimes are used. Gottingen is shortened in some references. DAN. stands for Danish, FIN. for Finnish and M.P. for Modellprofil (same as airfoil in English).

You are fortunate if you own such a motor because, unless you are lucky, find ^ 3 ^ ing one can be expensive. There are three EVER ways that you can acquire such a motor. The first is to buy and try, and rebuy, until you hit. The second way is to buy a motor and then buy extra parts, replace each part or parts until you find the com NOTICE bination that clicks. The third method is to purchase a motor from a firm that deals in, or reworks, motors and have them guarantee results. This latter method may look expensive but after you’ve had a taste THAT of the first two methods, it can be inviting. Some manufacturers prolong the useful peak of their motors by methods that will permit them to still sell motors at competi tive prices. One of these methods is to FUEL impregnate the walls with lead, another to temper the liner beyond the hardness of ' A l t the usual liner; third (a high priced motor) "UNNINO uses chrome sparingly in the interior. Further use of chrome can be made to CLAIMS prolong the life of a motor that is beyond the cost point of the manufacturer who must stay within the popular-price bracket. This more extensive use of chrome will cost about the price of an additional motor but SOUND will maintain the peak of a hot motor to the life of that of several other motors. I am told that chrome is bonded to the basic metal in the form of a network of lacy veins. While it may look solid to the eye, there are many small openings in the GREAT coating. Since the coating is not a solid wall, there is less friction between the piston and liner,- resulting in less drag, less wear and higher RPM. In addition, oil is caught in the openings, assisting in lubrica EVERYWHERE tion and cooling, again reducing drag and Take i f from your engine! wear.
