Everett Edgcumbe Monoplane
One of the earliest British tractor monoplanes was that designed in 1908 by E. I. Everett and constructed by Everett Edgcumbe and Co. Ltd., of Colindale, London, N.W.9.
The machine was reminiscent of the Bleriot Monoplane in lay-out, and was a single-seater powered by a four-cylinder 35 h.p. J. A.P. engine which drove a 6 ft. diameter propeller. The framework was of wood with fabric covering overall; the flying surfaces were double-covered. Warping was used for lateral control, and this was operated by turning the hand-wheel on the control column, the fore-and-aft movement of which actuated the elevators. Foot pedals controlled the rudder. The wings were given a generous dihedral angle, and at their tips were mounted end-plates.
In the course of tests, various alterations were made to the machine. The original undercarriage skids were curved along their length, the wheels' axle being sprung by the rear part of the skids. The arrangement of the supporting struts was altered to provide a more rigid fixing, with the transverse axle moved to mid-way on the new pair of skids' straight portion. The engine was water-cooled, its radiator being carried at an angle under the nose of the fuselage.
Tests of the Everett Edgcumbe Monoplane were carried out in a field at Colindale which was to become part of the London Aerodrome at Hendon. The wooden shed built to house the machine was used by Louis Paulhan for his Farman during his epic race with Grahame-White for the Daily Mail London-to-Manchester prize. The nickname "The Grasshopper" was applied to the monoplane, as it failed to fly properly and succeeded only in making hops from the ground during trials made on 6th and 7th December, 1910, by Bernard Clutterbuck and again during January, 1911, by E. I. Everett.
