HUMBER biplane 1910 type
This tractor biplane shared the stand at Olympia with the monoplanes in March 1910. It was a side-by-side three seater, with the instructor in the center with overriding control of the pupils controls, which were triplicated.
The uncovered fuselage, which was square in section, tapered down to the tail by curvature of the upper longerons. The structure was of wood and the tail surfaces were similar to those of the Lovelace monoplane.
The wings were spaced by four pairs of interplane struts at the front and rear spars, all being of tubular steel. A wide-track undercarriage, below the longerons, was braced to a pair of outboard struts. The spars were jointed for ease of transport and the trailing edge sections of the wing outer portions were flexible for warping. This machine was probably not flown.
Power: 50hp Humber four-cylinder inline water-cooled driving a 6ft 11in diameter Humber propeller.

Humber Tractor Biplane
At the 1910 Olympia Aero Show, Humber Ltd., of Coventry, exhibited, together with the le Blon and the Lovelace Monoplanes, a three-seat tractor biplane designed specifically for tuition purposes. The engine was mounted on the lower wings, the pilot being seated on the trailing-edge, with a pupil's seat on each side; triple controls were provided, with means for the instructor to override the pupil's movements. The mainplanes were made in three sections for easy dismantling, and all spars and struts - with the exception of the tail booms - were of steel tubing. A simple twin-wheeled undercarriage was located under the mainplanes, with a single tailwheel supporting the empennage, which was similar to that of the Humber Lovelace Monoplane. Lateral control was by wing-warping. The engine was a 50 h.p. Humber which drove a 7 ft. diameter propeller. Span, 41 ft. 6 ins. Length. 36 ft. Wing area, 482 sq. ft. Estimated speed, 50 m.p.h. Price, ?1,100.

AEROPLANES.
Humber.
Two British-built monoplanes of the Bleriot type are on view on Messrs. Humber's stand, as well as a monoplane and a biplane designed by Capt. Lovelace. The main planes of the last-mentioned are of 41 '6 span, and the total lifting surface is 526 sq. ft. The Lovelace type monoplane is of 29 ft. span with a total lifting surface of 232 sq. ft. In each the engine fitted is a 50-h.p. 4-cyl. water-cooled Humber.

THIS machine is specially constructed solely for tuition purposes. It has three seats, the pilot's seat in the middle and a pupil's seat on either side. The control is in triplicate, but a pedal solely under the pilot's command enables the effect of the pupils' movements to be suspended. All main spars and struts are of tubular steel with the exception of the outrigger spars that carry the tail.
The main spars of the main frame are jointed so that the machine can be dismantled in three sections. The control is the same as on the Humber monoplane designed by Capt. Lovelace.
