Mulliner 1 Monoplane
The first monoplane built by the Mulliner Coachworks Ltd., of Long Acre, London, and Northampton, was designed by Gordon Stewart and was exhibited at the 1910 Olympia Aero Show. It was a single-seat tractor, fitted with the eight-cylinder 35 h.p. J.A.P. engine driving a 6 ft. 3 ins. Spencer propeller. Warping lateral control was incorporated in the wings. Span, 33 ft. Length, 27 ft. Wing area, 220 sq. ft. Weight empty, 420 lb. Weight loaded, 605 lb. Maximum speed, 40 m.p.h. Price, ?450.

THE SECOND OLYMPIA AERO SHOW.
NEW British monoplane, built by the well-known coachbuilders of Long Acre and Northampton. The main planes have a span of 33 ft. and a chord of 6 ft. 6 ins., while the overall length of the machine, which has a total lifting surface of 220 sq. ft., is 27 ft. It is fitted with a 35-40-h.p. 8-cyl. J.A.P. engine, which drives a 6 ft. 3 ins. tractor screw of 4 ft. 6 ins. pitch. Stability and directional control are effected by a system of warping the trailing edge of the main planes, combined with the action of the elevator and rudder at the rear.

NEW British-built monoplane of very light construction, designed by Gordon Stewart, and built at the Northampton factory of Messrs. Mulliner, the well-known coachbuilders. The design is mainly remarkable for the skeleton-like frame that has been adopted, and the high finish of the workmanship. There are some parts, however, that we shall expect to see strengthened within a short while of this machine commencing its practical trials. The main planes have a comparatively flat camber, and there is even a tendency to reverse the curvature at the trailing edge. The wings are built up upon two main spars, the rear pair of which are hinged together to facilitate warping, which operation is performed by an inclined steering-wheel. The engine is carried right forward in front of the leading edge, and the pilot's seat is situated about two feet behind the trailing edge of the main planes. The machine is supported upon a pair of wheels mounted in a hinged rhomboid or diamond-shaped frame, across the centre of which is stretched an elastic spring that serves for the suspension. The main wings are braced to the "A" extension of the chassis frame, which is constructed of tubular steel.
