Weiss Pusher Monoplane
In the same year as the Weiss Glider, a power-driven single-seat tailless monoplane designed on the same principles was built during 1909 by Weiss himself and was exhibited by Handley Page at the 1909 Olympia Aero Show, together with a notice stating that a second example was being built by Handley Page for the Weiss Aeroplane and Launcher Syndicate Ltd. The Weiss type of wing plan-form, with its curved, swept-back leading-edge, was used on the Handley Page Glider, the H.P.1, H.P.3, H.P.4, H.P.5 and H.P.6 Monoplanes and also on the H.P.7 Biplane. A short nacelle was mounted below the wings, and contained a three-cylinder Anzani developing 12 h.p. which was installed behind the pilot. Gearing and chain-drives linked the power unit to a pair of 6 ft. diameter propellers which were recessed in the trailing-edge of the wings, the elevators being fitted immediately behind them, level with the thrust-line. Bamboo was used in the structure of the fabric-covered fuselage. The landing-gear consisted of skids, but the machine took off from a jettisonable four-wheel carriage which, it was claimed, would face the wind automatically. A guarantee of flight was offered with the price of ?500, but the machine, named Madge after one of Weiss's five daughters, never managed to leave the ground. Span, 34 ft. Wing area, 226 sq. ft.

FLYERS AT OLYMPIA.
Weiss (HANDLEY PAGE).
Readers of the "Flight" section of The Automoior Journal will recollect our description of the bird-like model monoplanes constructed by Mr. Weiss. The machine which Messrs. Handley Page exhibit at Olympia is a full-size flyer on the same lines, and has also been built by the inventor himself. Like most work which has been put together in this way, the flyer is naturally somewhat rough-and-ready in appearance, for practically the whole of the framework is built up of cane, and this is a material which does not lend itself very well to neat jointing.
The Weiss flyer is of the monoplane type, and is peculiar amongst such machines in having no tail whatever. Let into the rear edges of the main wings, however, are a pair of righting planes operated by pedals so that they can work in unison for ascending and descending, and in opposite directions for steering and righting. Another peculiarity of the construction of the wings is their double curvature at the tips, it having been found from the gliding experiments with the models that everything depends upon having this curvature absolutely correct. Propulsion is effected by two propellers placed between the righting planes and the rear edges of the main planes. These propellers are chain-driven from an engine which is situated immediately behind the pilot. The machine, although comparatively small in appearance, has a considerable extent of supporting surface. As yet no actual man-lifting flight has been accomplished.
