Model Aircraft BY GEORGE W. WATERS. join in the fight with five other aggregations for the club cup, awarded annually by the District of Columbia Model Aircraft THREE newly formed model aircraft clubs in the District will League to the club collecting the greatest number of points the entire season. durin, Tie cup at present is held by the Chevy Chase Aero Club. The three new clubs are the Adams Flying Club, under the direction of Hubert H. Cleary; the Wheatley Model Aircraft Club, directed by Miss Susanne S. Mellichamp, and the Washington Model Flying Club, under the direction of Edward H. Young. Selecting Crack Pilots. The latter organization has al-| ready started selecting the best model pilots in the District and, like the other seven clubs, is vir- tually sure of bringing the large silver winner’s cup to its head- quarters. Well, if this year’s com- petition for that cup is as close as it was last year, it is going to be a real fight. s Robert Towles has been elected president of the Washington Fly- ing Club. John Sullivan is vice president and Robert Starkey sec- retary. The other clubs in the race for the cup are the Capitol Model Aero Club, the Macfarland Model Building Club, the Takoma Model Aircraft Club and the Pow- ell Aircraft Club. Aircraft Council Meets. The council of aircraft ad- visors of the District Model Air- craft League met yesterday, with John Williams, model plane in- structor, as chairman. Plans for the meets every two weeks until the finals, during the last two weeks in August, were discussed. The league will hold an outdoor model aircraft meet at Bollin Fleld next Saturday morning a 9:30 o'clock. Bruce Le Gore, president of the Aviation School of America, whose chief interest seems to be in giving youngsters a chance to become great aviators, will turn over his aircraft plant out on Kenilworth avenue on Saturday mornings to any youngsters who wish to come out and work on their models. It is understood that Mr. Le Gore and officials of the District Model Aircraft League will talk over the offer in the near future. Le Gore has a fully equipped plant and promises that the boys can make use of a:ost of the machines installed ere. Dornier Dox Model Shown. The crack aviation editor of a local paper here, who has re- putedly worn the same hat since Noah and the boys went “arking,” worked up some enthusiasm over model planes the other day. He stated in his daily column recently that he couldn’t get en- thused over model ships., Last week his column stated: “It you want to see a real nobby model of an airplane, go up and get an eye full of the famous Dornier Dox, the German flying boat which carries 169 passengers at once.” And that writer with the fa- mous hat had a right to be en- thused. It's really a marvelous model. The model, which was on display last week at the May- flower, was brought from Ger- many by Lieut. C. H. Schildhauer, formerly of the Navy and now with General Motors. It cost $1,500 to build the all-metal model. Another model of a four- motored, 27-passenger ship also was exhibited. Just a Chummy Meet. Speaking of enthused aviation writers—you model plane pilots would have gotten a big thrill if you could have watched a certain aviation scribe here and a prom- inent business man industriously flying a model plane in the lat- ter's office the other day. They were weighing down the tiny plane with paper clips in various sections of the wings and fuselage in an effort to send the plane into loop-the-loops, tail spins and sideslips. And the great part about it all, boys, was that they succeeded with the first two gyrations. The sideslip was a bit too difficult for them, however. More power to them. Frank Salisbury, crack model plane pilot, writes in a line about his club. “Our new club is called the Washington Model Flyers Club and meets at the Washington Model Aero Supply House, 1101 Thirteenth street. This club is composed of some of the best model pilots in the city, and romises some stiff competition to he other clubs in the District. “The Capitol Model Aero Club, which also meets at the above ad- dress, is looking for new mem- bers as it has been reorganized and is going to do its best to win the Committee Club Cup. “S8am Walker is the new secre- tary and he is working on the rules and point system for the transcontinental air race, which the club will start soon. ALEXANDRIA AIRPORT CLAIMED BUSIEST Three Flying Schools and Six Training Planes Use Field Daily. With three flying schools using the fleld and six training planes operating there daily, Alexandria Airport, operated by Mount Vernon Airways at Hybla Valley, near Alexandria, Va., is claim- ing recognition as the busiest Virginia airport north of Richmond. The schools now giving flying train- ing to students at the Alexandria field are the Mount Vernon School of Aero- nautics, which now has 20 students un- dergoing flying training; the District of Columbia Air Legion, local flying club, which has soloed 23 students there du; ing the past six months, and the Stan ards Flying Club, composed of employes of the Bureau of Standards. All three of these schools have or- nized glider units, and glider flying expected to begin there this Spring. ‘The Standards Flying Club glider unit placed its order for a primary training lider during the past week, and de- very is expected soon. Fifteen Mount Vernon students have been graduated and have obtained their Department of Commerce pilots’ licenses during the past six months, according to the.fleld records. The District of Columbia Air Legion during the past week put six students up for the De- partment of Commerce flight test for pilots’ licenses. A program of construction and im- provement of the airport is being plan- ned for this Spring by E. W. Robertson, president and fleld manager. Flying activities will be under the direction of Robert F. Strange, chief pilot. et ARCTIC FLIGHT BY GRAF IN SCHEDULE FOR 1931 International Aeroarctic Associa- tion to Push Plans for Trip for Scientific Investigation, Plans for & 1931 polar cruise by the Graf Zeppelin are being - formed by Aeroarctic, the international society for the cxploration of Arctic regions by air- The expedition will be undertaken for sclentific investiga . nally scheduled for April and May of year, but sbandoned when the Zeppelin company could not obtain un- derwriters’ insurance on ship and crew. ‘With all tions made, includ- ing the fitting of a landing fleld at Fairbanks, Alaska, the venture will be pushed on to completion, accordin, John A.

Flying the equivalent of one-fourth the way to the sun, instructors at Air Corps schools have gone a total distance of 25,000,000 miles in seven years. One fatality was averaged for each 5,000,000 miles of travel. o +T. J. WAGGY, ‘Who has been elected general ma; of the District of Columbia Air Legion, local private flying club. Waggy won his private pilot’s license from the De- partment of Commerce during the past week.

ARMY FLYERS CUT VOCABULARY TO ‘WORDS AUDIBLE IN PLANE Although it should be the ambition of #very one to bulld up & Jarger and bet- o bove ‘the vantage above e motors. A communication to the Alr Corps news letter from Rockwell shows that the vocabulary for use on the flying fleld now has been cut down from & first elimination list of approximately 500 words to an even 100 words. ‘The “anti-noise” vocabulary not only but becomies even roar of air- irt- g il g 1 e af £ e g : to it the g 5 il : | the Aviation School of | than THE SUNDAY PILOT MUST THINK OF THREE MOTIONS “Rocking Boat” Declared Best Way to Break Peril- ous Craft “Spin.” Problems of balance, stability and control of airplanes are intricate when, the 36 possible combinations of motion are considered, but, fortunately for the pilot, he need only think of three, Dr. Hugh L. Dryden, chief of the aero- dynamics section, Bureau of Standards, told members of the Standards Club at its regular meeting during the past week. These three principal forms of mo- tion are freedom of the ai to move about any one of three axes or combinations of them; the pilot ma: “roll” his plane about the longitudin axis, “pitch” it like a ship bobs up and down on water about the lateral axis, or he may “yaw” it by steering to the left or rm:lt nbodu': mamulhflxh.m Dr. len ! “8) r{le stated that m lkl{idl.n‘ e;ect usually begins just as the plane is about to stall, forcing the outside wing, wl el leu'emtlmt angle, the outside wing having a greater lift under these con- ditlons. # Pilot Loses Control. This sets up a revolution, sometimes called auto or self-revolution, because the pilot has lost control, forcing the plane to spin at the rate of about one turn in every three or four seconds about its fore-and-aft axis, until it reaches the earth, unless the pilot re- gains his control. When a plane spins it loses from 200 to 500 feet in altitude per revolution, and since two or three revolutions occur before control is re- gained, the pilot should be at a mini- mum altitude of 500 to 1,500 feet. Dr. Dryden suggested that the remedz to get out of & difficult spin is to “rocl the boat,” that is, to g‘ the plane rock from side to side and thus, with the control stick, break through the stable motion of the spin. An- other way is to get the aircraft oscillating by rolling it with the con- trols and at the same time lmlanuns and sharply turning the engine on an off, he said. Glider Activity Predicted. Dr. George W. Lewls, director of aeronautical research of the national advisory committee for aeronautics, pre- dicted ‘great activity in the use of gliders during the coming Summer and said he looked forward to considerable competition between the different clubs that have been formed here recently. Victor L. Lowe, secretary of the Standards Flying Club, annouriced that the newly organized glider section of the club had collected all but about $100 of the $465 needed to purchase its glid- er and that the lists for the present unit would shortly be closed after the receipt of a few more applications for membership. The order will then be placed with the manufacturer. Mr. Lowe urged that members of the glider section attend regularly the edu- cational and theoretical lectures being given before the club each Tuesday evening, inasmuch as gliding is & - tical preparation for powered 3 and the study of a theory of flight and allied subjects covered by these lec- tures should not be omitted because of glider activity.

The slow-motion “flight” was in the nature of an emergency Lieut. R. D.

Practically speaking, also, if you fly 2 miles in any direction you are off the map.” A link in the empire airways joining Austfalia and London “is not more than two years away,” he said. This will make a route nearly 17,000 miles in length, through Delhi, India, to Sydney. The one handicap of European flying was ascribed to the fact that there is absolutely no freedom of the air.

In Germany the controflability in stalled flight must st be regarded as an unsolved problem.” Tanager Is Cited. In this country some of the most difficult problems’ controlling the flight of an airplane at stalling speed have been solved in the Curtiss Tanager, winner of the recent Guggenheim safe airplane contest, wing slots and flaps and full floating ailerons being used to give control after thé normal angle has been passed. “In judging the present state of Ger~ man airplane development,” Hubner sald, “it should be remembered that their period of evolution has been a very short one and that a great number of "technical and economical difficulties had to be overcome.” The difficulties encountered by air- plane nilots and laboratory trained sei- entists In reaching a common ground of understanding, which has been largely overcome in this country, spparently has been a troublesome lem in Germany also. Averse o Theory, “Pllots,” Hubner says, “have an svei slon to theoretical considerations. More- over, their vocabulary is so peculiar that they cannot be easily understood by formal theorists, The latter, thus left to themselves, hckr&mucnl experience which, in this particular field, ecannot always be replaced by any amount of theoretical knowledge.” The chief purpose of the German aeronautical industry after the wa: was to attain great economy, Hubner ex- plained. It was realized early, however, that there could not be econmy witheut safety, and it became apparent that the development of good airplane flight characteristics was one of the vital ob- Jjects to be attained in civil aviation.
