I’M suffering from Ultra-Light Nostalgia and am trying to forget: the present-day apathy on the part of officialdom for private-owner flying by delving into the past. I must say this has strengthened enormously my faith in the really low-power light nerophine. In spite 4,f ” Lymptie laments,” Fbing
Flea fiascos mid ” pessimisms, I maintain that. the light and ultra-light aeroplanes built over the two past decades primarily for the purpose of making private-ownership a practical possibility–which, after all, is what we are still st.riving fur–really flew very well loot thoroughly justified themselves. Let use refresh your memories, and then you can decide for yourselves
Soon after the Kaiser war the Austin Motor Company produced a metal singleseater biplane with folding wings and a 50-It.p. six-cylinder Anzani radial engine!. This aeroplane weighed 580 Ili; well within the 1.20011). limit recognised to-day by the Ultra-Light. Aeroplane Association. Designed by John Kenworthy, the Austin climbed at the rate of 500 ft. per minute. A. V. Roe went, if anything. one better, for their soon-famous A vro ” Baby,” using merely a Converted 35-11-Pt;reen Wkiter-cooled stationary engine, left Croydon during May, 1920, with. Bert flinkler at the controls, and flying through thick fog near Paris, it crossed the Alps and landed, 9A hours after taking off, at ‘Eurin. It had averaged 68 m.p.h. for the journey
consurned petrol at the economical rate of 32 m.p.g. Bather a (lassie performance, surely, for a very normallooking. not specially faired biplane built thirty years ago. The germ of owner-pilotage was contained in these and similar little aeroplanes and, in spite of the post .war slump, it received encouragement in the early nineteen-twenties which emphasises the apathy of the present. day. Indeed, the financial low-ebb which threatened to cripple the industry actually served
to further the ultra-light movement, for it was optimistically thought that factories would be able to remain open SUpplying the private-owner demand auc I that the military authorities would be interested in appreciable quantities of tiny aeroplanes for use as trainers.
If things didn’t shape that way it wasn’t the fault of the Daily Mail and the Duke of Sutherland, who don tied the principal Prizes, totalling £2,118). for the leympne Light Aeroplane Contests of 1923. the rules for which strove to test Iii)) only speed but economy, attitude, reliability and manoeuvrability on the ground. Twenty-eight entries were received. itieluding nominations from such famous firms as Avne, de Davin:end, Gloster. Viekers, Ilandley-Page. and Parnell. Every day, as the week of the contest drew near, the enterprising Daily 3101 published news and fascinating philtres of aeroplanes of hitherto 11mb-carnet] of diminutiveness being assemlileel. laing wheeled single-handed through narrow gates and across fields and, oecasioi tally. being flown in Bre Kentish sky.

An invigorating ainwspliere of rivalry and a sense altruist of pioneering pervaded the flying field and penetrated into the wartime hangars. It was new and all very lilt rigning. I know about the pessimisms which history justified. I low over-stressed motor-cycle engines overheated, seizedup solid. broke valves.

Yet out of it all emerged some’ excellent performance figures. The Abtlidia Speed Prize was won the Douglas-engirwel Parnell Pixie monoplane, it no less than 76.8 m.p.h. The Sutherland and Mity Mail prizes were worm jointly by the A.N.E.C. which climbed I() 14,400 feet and averaged $7.3 m.p.g. of petrol and by the Wren, which equalled this excellent fuel consumption.

Folding or easily-detachable wings were again stipulatelt and, Intel the 550-e.e. per passetwer limit not hampered performance, some very usefill aeroplanes might have resu t ed.
As it was, three speeial engines wen, evolved to meet conditions with which converted motor-evele units could hardly hope to comply. These were the AIM:1Di, the A.B.C.. and the Bristol Cherub, the last-named a horizontally-opposed twin developing 32 b.h.p. at 3.900 r.p.nt. for a weight of just over 90 II).

These Machines were a credit to the ingenuity Of the industry. Their average weight was approximately 834 lb. anti their average wing loading about. 4.31 lb./sq. ft. Nor did the better examples fly too badly. The Bristol Cherub-engined Beardmore Wee Bee won the major award, with ‘a speed range of 39 to 71 m.p.h., while it. Cornper’s
covered 702 miles in 11 flying time of 17 hr. 58 min.
Those, ‘then, were the sort of performances possible with single and twoseater ultra-lights over twenty-five years Alas, after the 1924 contests small aeroplanes grew up.
