PEED is the keynote at Lockheed. Speed of production and speed of their products. Lockheed’s P-38 inter­ S ceptor for the army air corps and for Great Britain breaks 400 m. p. h. with its two Allison engines. The famed Hudson, of which more than 1.000 have been built for Great Britain, has distinguished itself for ruggedness under fire. Its high speed and all-around performance make it popular A M E N D THE CLOCK with the British. The civil counterpart of the Hudson, the “ 14,” and the similar-looking but newer Lodestar transport are the fastest ships of their type in the world. Based on the Lodestar is the new Ventura bomber for the English. Lockheed and Vega, the airplane company, its subsidiary, expect to work 50,000 people around the clock for peak production. Lockheed's streamlined Vega monoplane set new standards for speed and efficiency during the ’20s and ’30s. Looking forward to the tremendous growth of civil aeronautics after the war, and the immediate stepped-up production of fight­ ing airplanes, Lockheed recently purchased the Burbank Union Air Terminal, one of the nation's largest civil ports. Foreshadowing future civil production are T. W . A. and Pan American orders for forty of the giant four-engined Constellations apiece. These will be 64-passenger, four-engined planes, with a top of 350 m.p.h., range of 4,000 miles, and a 30,000-foot ceiling. Engines will l>e 2,500 h.p. Wrights not yet in pro­ duction.

The commander of the K-2 takes you on a practice flight out over the Atlantic, demonstrating just how blimps would be valuable to us in case of war.

LMOST two hours had passed since the rise of the sun, but still you couldn’t see it. The clouds were heavy gray masses that filled the sky Afrom horizon to horizon, racked and tumbled by a biting breeze born among the icebergs. The Atlantic, a hundred miles offshore, was a waste of sullen green swells and dirty white scud, and as lonesome as the moan of a whistling buoy in the night. The freighter was on course for Philadelphia, her blunt bows shoulder­ ing stubbornly through the unfriendly combers, her rusty plates streaming spume after every lunge. She was heavy with cargo, low in the water, and couldn’t have been logging more than ten knots; if she sighted land by nightfall slic’d be doing well. Both of the figures on the bridge were in oilskins, but the mate wore an old cap with a visor and had a pair of binoculars slung around his neck on a thong. These last he was using to scan the murky horizon with concen­ trated intentness, holding them steady over the forepeak for a minute at a time, and doubtless cursing the limited visibility. Suddenly he stiffened,

bracing himself as the ship rolled out of a trough. The glasses swung hastily from one side to the other; then they dropped from his hand to stop with a jerk at the end of the strap. He lifted an arm to point, and his mouth opened wide with surprise. He needed no binoculars to see what he was now pointing at, though it had not drawn his attention before. He had noticed first the faint hum of throttled motors; now, looming abruptly out of the scudding clouds, he saw a shape like a huge silver sau­ sage. The nose was bluntly conical, and where the tail tapered were four flat fins symmetrically arranged; underneath was some­ thing like a streamlined blister with a row of windows all around. But all that is how things must have seemed on board the freighter, the way we looked to them as we floated out of the clouds. Aboard the blimp, I slid open one of the windows and picked up a megaphone. From a height of a hundred feet my voice carried easily. “ Alloy!” I yelled. “ What ship is that?” At first I couldn’t understand the mate’s reply. I thought for a minute he was using a strange tongue, and asked the ensign at my side if he had the foreign-language vocabularies handy. But then the mate ducked into the wheelhouse and reappeared with a megaphone of his own. His shout came loud and clear, with a marked Scandinavian accent. First the name of the ship, the registry; then, “ Out of Recife, bound for Philly!” Ship's navigator carefully plots each ocean petrol flight to cover I asked several more questions, noting his replies on a special maximum eree.

Then I waved the megaphone at him. “ Respects of the navy— and the best of luck!” A second figure in a peaked cap, hastily buttoning his oilskins about him, came up a ladder to the tramp’s bridge; that would be the captain. I could see the mate pointing in my direction, reporting the unexpected lia.il. The captain seized the megaphone. “ Are we at war?” he bawled at the top of his lungs. I grinned as I shouted back: “ N o! Routine practice flight!” The two Pratt & Whitney engines mounted outside on either side of the gondola, which had been turning up just enough to hover the K-2 into the wind over the freighter’s position, now revved up -under opened throttle. Our nose lifted, and the blimp rose in a gentle curve toward its previous course until the bulk of the envelope was nearly hidden in the cloud layer, only the observation ports remaining down in the clear. Looking back down at the bridge of the lumbering steamer, I could see the two officers staring after us. The mate was ges­ turing; I could almost guess what he was saying. “ A fine chance we'd have of getting anywhere near an American harbor if we were an enemy mine planter, huh!” And the cap­ tain’s response; I’d almost bet on that, too: “ I thought they’d chucked all them things in the dust bin since the last one burned up— what is it, the Hindcnburg?” There are doubtless many others who suffer from tliat same Forty winks ere snatched by one crew member es blimp continues its misapprehension; that the series of airship disas- (Turn lo pane 28) slow petrol over the ocean.

The old story of learning to fly that's al ways new—told by a traveling salesman.

BY WALTEB E. EDWARDS

Ο υ have never heard this one about a traveling salesman! Selling steel for a big company has its ups and downs. Ϊ But even if you are on the “ up,” in Bridgeport, Stam­ ford, Hartford or New York, you can always look up and see those lucky devils flying in planes go still higher. So, living in Garden City, I decided one week end to step over to Roosevelt Field and have a look-see. . . . Well, there I was, a registered student, a contract in my jeans, waiting for the first dual hop. Had never been up before. It wasn’t bad. (That fellow Bill Turso sure can fly — lie’s got five thousand hours.) Sure, the first hop wasn’t Don't worry, it's strong enough to hold you even if you ere big. Bill, left, assures Walter that the rugged training plane can really take it. bad— but that’s because I finally got down. Gentle reader, remember, if you are interested, I went into this business as cold as a nude Eskimo. From the gunning of the throttle on the take-off to the three-point (thank Heaven) landing, I was scared. Being fundamentally a little reckless by na­ ture, I have since been glad o f this original fright as I think it has made me a more careful pilot. That too-true observa­ tion of Horace Greeley, “ Your hindsight is better than your foresight by a damn sight,” can never be applied to a pilot. If your foresight isn’t good, you’ll never be around to figure out your hindsight. My knowledge of aviation was nil. Thus my decision to attend a Grade A school. Roosevelt Aviation School, I knew, offered a first-class ground school as well as proper equip­ ment for flying. The curriculum I obtained, the equipment I saw, and the meq I met, sold me on my first visit. In the ground school I learned that a pilot’s problems are not all with his ship. Meteorology, navigation and civil air regula­ tions must be as integral a part of a pilot’s make-up as his co-ordination of stick and rudder. Mr. Cappe, fondly known Down-the-hose directions.

If it is the development of private flying that is desired. the average citizen T h a t ’s a should l>e encouraged to fly, and such irrelevant questions be deleted from the examination. The first of the exam—on regulations— also stressed many' questions such as “ Can a pilot having a Class 2S rating fly a Class 4M plane?" This question seems a bit far-fetebed lo ­ S I L L Y R U L E calise no private pilot is going to fly a DC-3, and if the ex­ aminers want to know if the applicant is aware that he can fly any ship solo, but can carry passengers in only such weights as he is rated in, they should devise the questions accordingly. The second lialf of the examination— on meteorology and navigation— is partly essential and partly nonessential. It is well to know some weather, some clouds, and how to read a teletype weather sequence— especially if cross-country work is the type of flying one has in mind. But some of the navigation is hard and of no practical value because it simply cannot be used by the average flier. As the average pilot will testify, cross-country work is done with an automobile map. The pilot draws a line from his airport to the next one, and gets a good idea of the angle. The mileage is measured off, anil the time of arrival computed; he knows that his plane will stay aloft only so long, and tries to reach an airport within that time. The wind is not too essential, because it is not very effective under 15 m. p. h., and "A lot of the C.A. A.requirements for a private in anything stronger than 25 nt. p. h. he will not venture to license are pure boloney and I can prove it!" take a Class 1 plane, and probably not a heavier ship. So the wind will make only a slight difference in his calculations.

CHAMPIONSHIPS

Is your visit to the Chicago jamboree still a dizzy blur? Cheer up—here's what you saw and heard!

B O U T 1300 model builders turned up in Chicago the first week in July for the 14th Annual National Model Airplane AContest. Army and navy service and defense work kept many others away. Cutrency regulation kept practically all the Canadi­ ans at home. Several model builders came up from Mexico. One of them took a second in the best-finish event. New Zealand entered several models in the Moffett Trophy event. These were entered originally in the 1940 contest. Prior to the contest this Line forms to the right. Usual queues of sunburned con­ testants waited at a dozen tables for processing models.

HE Nationals are rapidly becoming a competition— in the full sense of the word— losing some of the “ fair" atmosphere they Tused to have, when each fellow wondered what his neighbor had dreamed up. For, with the contest rules unchanged for two years (minor miracle), the general design of the contest ship has FROM T H E S E become quite stabilized. Experience demonstrated the soundness of the set-up of parasol, polydihedral wing and long tail moment arm with large stabilizer for obtaining the stability required to handle great power. Most design changes therefore ran toward DESIGNS— the refinement of individual parts such as airfoils, pod and boom fuselages, retractable landing gears, folding props, et cetera. H ow ­ ever, never let it Ire said that modelers have become stagnated in BY HENRY STRUCK design, but only that the record number of competitors concealed what may prove to Ire next season's tried-and-true fliers. The Chicago Tim es and the Chicago Park Department com­ 1941 's National Champ analyzes and bined to make this meet the smoothest ever run. The absence of the usual long lines, with timers and runways always available, forecasts as per ships seen at Chicago. was enough to warm the heart of any long-suffering contest goer. Only the weatherman failed to co-operate fully. Before he could lock up the breezes for which the Windy City is famed, the first three days of the meet had passed, and with them the chance for wholesale record smashing. There was plenty of good flying, though, accompanied by much strenuous legwork through the deep grass. That same grass, however, saved many a ship to fly again in spite of a test crack-up.

GAS-POWERED MODELS Class A used to be distinguished by obvious attempts at extreme lightness to make the weight rule, Class B by harboring most of the efforts at “ super-duper” design, and Class C by being the most realistic. These conditions have passed. Contest ships now seem somewhat like those tricky advertisements whereih a gentleman lounging in an easy-chair contemplates an advertisement of an identical man who in turn is doing the same thing, and so ad infinitum,. The only real difference is size. The new engines around .34 cubic inches have given Class C jobs fresh im|X'tus, especially for those who have no means to transport or build six-footers.

And what's more, you have an already tried. airplane that looks like an airplane. The actual working mechanism which makes it possible to control the flight path of our control-line model, a Vultee Van­ guard, described in the article following, consists of hinged elevators, the movement of which is controlled by two lengths of piano wire. The two wires are attached to a simple mecha­ nism located directly at the center of gravity of the model and, by pulling one wire the elevators move downward, causing the model to dive. By pulling the second wire the elevators move upward, causing the model to climb and eventually loop. The end of each wire line is attached to a handle which the pilot (that's you) holds. By tending the wrist toward or away from you slightly, pressure is exerted on each line, which in turn moves the elevators either up or down. The use of two con­ trol lines minimizes danger of injury to s|>ectators due to line breakage. In the event one line breaks, the other will either dive the plane into the ground or throw it into a series of loops, either of which prevents its flying off into spacei The mechanism inclosed within the fuselage of the model to convert the "pull" of the two control lines into up-and-down elevator movements is merely a combination of two levers. (See Diagram A in following article, “ Pilot this Vanguard!") By pulling the front wire the control plate is moved, causing the elevator-control rod to move forward, thereby moving the elevators down.

Flying scale models like the author's Vanguard can be mada to dive, zoom, and even loop, all in response to the pilot's manipulation of the elevator wires.

H E Vultee Vanguard presented this month, adapted for “ con­ trol-line flying,” is a one-inch-to-the-foot scale replica of the Ttype now doing yeoman duty across the puddle. The original model had the total weight of twelve ounces, and was powered with the new Super Atom engine, but any Class A or II engine may be satisfactorily used. Oddly enough, the engine displace­ ment for control-line flying does not alter the flying qualities of the model to any great degree, the only noticeable effect being an increase in speed.

First obtain two blocks of very soft balsa each measuring 25" long, 6" deep and 2J4" wide. Trace the side view on each block and cut out with.a coping saw. Cement both halves lightly together and shape the outside with the aid of the cross-section fuselage contours. After the outline is fully shaped and sandpapered, cut away the glue joints and hollow out each half with a gouge or similar instru­ ment. After hollowing out each section to correspond with the

N. E. (Jim) Walker, manufacturer of American Junior ready-to-fly model air­ planes and the U-Control Fireball, builds “ DON’T QUOTE ME!” and flies radio-control gas models as a hobby. This year he won that event at Talk of the trade as overheard in factory, field, store. the Nationals. T o our mind, his model was one of the most practical there. It controlled perfectly (Jim would “gun” her on the banks), had about a six-foot span and a stock Brown Jr. engine with two timers. Can this be the beginning of radio control for the advanced gas mod­ elers?

Not a "box," yet easily built, this rugged competitor features con­ sistent flights and long contest life.

H IS ship, built to Wakefield specifications, has teen named Glamour Girl, because' of the many curves in the right Tplaces. Tested in a number of contests. Glamour Girl lias left little to lie desired as far as performance is concerned. The ship has a very fast spiral climb, and a slow, lazy glide. Both climb and glide are to the right. Well, since talking about it will not get it built, let’s get started.

CONSTRUCTION The fuselage.is built up of the two main sides, with '/%" stpiare longerons and cross braces, and ’/ ,« x '/&" diagonals. The diagonals add little weight but give perfect bracing against the twisting strains encountered- in high-powered rubber jobs. The diagonals also take up the strain when a longeron snaps in the Jieat of competition. Choose your material carefully, using hard stock throughout the entire fuselage, as this is where most of the hard knocks will be absorbed. After making tbe two sides, join together as per plan view of the fuselage. Be sure to use accuracy in scaling up the plans, and follow the dimensions given. After the two sides are joined anti dry. sand this part of the fuselage thoroughly, first (Turn t o page 60) The author demonstrates '.'unassisted" take-off under Wakefield rules.

CHOICE OF CHAMPIONS

Another champion, Sal Taibi, First Place Winner in Class “C”, Open Division 1941 National Champion­ ship Meet, used FLO-TORQUE props on his winning flights.

Sal is a consistent user of FLO- TORQUE props and has this to say:

“ 1 am writing this letter because I am sure you would like to know that I was using FLO-TORQUE props on my winning flights in Class *C\ Open at the 1941 Na­ tionals.

1 think FLO-TORQUE props are the best that can be obtained for flying gas models.

Acronautically yours,

Sal Taibi”
