NEW AEROPLANES IN KING'S CUP RACE

D.H. TECHNICAL SCHOOL "T.K.1"

  This somewhat cryptic name has been given to a light two-seater biplane which has been built in the De Havilland Technical School. It was designed by Mr. M. Langley in order that the students of the school might have more profitable and more interesting work than rebuilding machines of existing designs. It is a fairly straightforward biplane on accepted lines, with very little stagger and no sweep-back on its wings. The gap is unusually large, and the rear flying wires are carried forward from the top rear spar to the bottom front spar root fitting, making it easy to get in and out of the cockpits. The machine was originally designed to use the "Gipsy IV," a small inverted four-cylinder engine of 80 h.p., with which De Havillands were experimenting some time ago. This has now been replaced by a "Gipsy III" engine, with, of course, a consequent increase of performance. Geoffrey De Havilland, jun., who also acts as instructor to the Technical School Flying Club, will be flying the machine in the Race.
