Full details of the single-seater were published and included estimated performance figures. The fuselage was of steel tube construction with light alloy covering, welded and fabric covered aft of the cockpit. Tail surfaces were also steel tube with fabric covering. The wings were of two-spar wood construction with mainplanes built separately, the leading edge ply-covered and the remainder fabric-covered. Frise ailerons were fitted and the fin and rudder were mounted ahead of the elevators in the interests of good spin recovery. The fixed tricycle undercarriage was compressed rubber sprung and had identical-sized wheels. The nosewheel was castering and self-centring but not steerable; it originally had a spat which later appears to have been discarded. Brakes were applied by a hand lever with differential operation by the rudder pedals.
The engine was a 36hp JAP flat twin which it was claimed would provide a cruising speed of 75 mph and a maximum speed of 84 mph at max continuous 2400 rpm. At 2250 rpm at 5000 ft endurance was to be 3 hr 48 min, range 265 miles. However, if 265 miles is divided by 2.8 hr the result is 70 mph, so somebody was cheating! In any case the figures were estimated and never confirmed by flight tests. The dimensions given were: wingspan 29 ft 4 in, width with wings folded 9 ft, length 20 ft 9 in, height 7ft 1 in, wing area 145 sq ft.
Why taxi trials and low hops were not followed by flight testing was not stated, and if there were any problems they were not revealed, but it appears that orders were not forthcoming and further development was not funded.

Регистрационный номер: G-ALYA The Hants and Sussex Herald. The upper part shows a Flight photo of the airframe before covering. The lower part shows the Herald discarded without engine but still on its wheels.
Aeroplane May 28th 1948 *p.628 - Good progress was reported by Hants & Sussex Aviation at Felpham on the prototype Herald single-seater. Originally Nuffield powered it was now to use a 40 hp JAP J-99. Designed to ARB aerobatic criteria, it has a regular planform for good stalling characteristics and simplified construction. A low-wing design, with wide track nosewheel landing gear, the fin and rudder are set forward of the horizontal tail surfaces at the end of a long fuselage to improve spinning characteristics.
A: 28.5.48 p.628: The Hants & Sussex Herald G-ALYA, c/n HS/AC/001, made only a few ground hops at Portsmouth in 1953 and was dismantled in 1954.
A: 28.5.48 p. 628 - The Hants & Sussex Herald was not dismantled in 1954 (see p.94/75) as photographs, one of which is dated 9.55, show it minus engine, out of doors and apparently discarded but otherwise still intact. H&S announced that the Herald was intended to be a testbed for a 2-seater to fill the gap in this class in Britain at the time.
