elevator, and both types had a fixed triangular fin. On the H.P.22s this carried a rectangular, unbalanced rudder, but the H.P.23's rudder was rounded on the trailing edge and horn-balanced. The open cockpit was ahead of the wings and the undercarriage had two small wheels, mounted inboard on the fuselage on the H.P.22 and outboard on the H.P.23. The main differences between the two types came about because the H.P.23 was designed for the speed prizes rather than those for flight duration. It therefore had a much shorter span of 20 ft (6.1 m) compared with 36 ft 6 in (11.13 m) for the H.P.22. This wing had full span leading edge slots and camber changing flaps. Both types had their engine mounted on a pylon immediately ahead of the pilot. The H.P.22 used a 397 cc

No.23 proved impossible to get airborne, even when the little ABC was replaced with a 500 cc
Douglas. No. 25 was therefore reworked: the wing was lowered to shoulder height with its incidence increased to 7°, the ABC engine was faired in and the cockpit faired over apart from two small viewing

As originally completed, all three aircraft had much in common. They had almost constant chord wings that carried ailerons fitted with slots for low speed control. The fuselage was of square cross-section, with the underside tapering towards the tail. There was no fixed tailplane, only an

Handley Page began using the familiar H.P. numbering system they retrospectively named the initially similar no.23 and 25 the H.P.22 and no.26 became the H.P.23.
