The tailplane was of steeply swept delta plan like that of the Type D, but carried twin elevators of roughly half-heart shape.

The pilot warped the wings by turning a wheel mounted on a lever which could also be moved fore and aft, operating the elevators.

[1] These engines were well regarded but produced a lot of hot oil, so a half cowling was installed to shield the pilot.

[3] This structure was stiffened and the aircraft protected against nose-over by a long central skid which curved upwards well forward of the propeller, mounted to the fuselage by a fore and aft pair of inverted-V struts and also joined to the axle hinge.

[1] The Type E made its first straight hops on 26 April 1912 at the Handley Page field at Fairlop and was soon performing well enough to fly to the works at Barking, piloted by Edward Petre.

[1] On 27 July it flew from Fairlop to Brooklands on a complicated 55 mile route avoiding the built-up parts of London.

Handling was improved and several flights were made with three passengers before the aircraft was spruced up for its appearance at the Olympia Show in February 1913, where it was inspected by King George V. Immediately afterwards a new wing was fitted with the wing warping system replaced by ailerons formed by hinging the outer trailing edge extensions; the earlier side-to-side rolling characteristic was cured.
