12 FLIGHT. JANUARY 3, 1935. A NEW MONOSPAR The " S.T.12" with tzvo 130 h.p. "Gipsy Major" Engines : A New Type in the Well-known Monospar Range, Offering a Higher All-round Performance IN the normal course of events, when a manufacturer produces some piece of apparatus—a car, aeroplane or fountain pen, for example—people rapidly become used to it, and then want something better. Ever since they were first brought out, the General Air craft Company's Monospar aeroplanes have been improved from time to time, but with out radical departure from their original sound layout; this design was so obviously what was wanted that there has been no demand for alterations.

"Gipsy Major" engines have been mounted in a similar fashion to the Pobjoy engines previously used ; that is to say, they are carried on steel-tube mountings projecting from the wing spars at a point in the stub wing just forward of the hinge which allows the wings to be folded.

Both sides are idfntical. The shock-absorbing rubber blocks are carried in each of the rectangular undercarriage legs. teristic for which the earlier Monospar models were famed— has been retained. In other respects the "S.T. 12" is similar to the "S.T.io," which was fully described after it had won the King's Cup Race last year in such a spectacu- JP
