folding the wings. Large wing flaps are fitted to the top wing only, and so arranged as to act as camber flaps, as well as ailerons. They are held up by rubber cords on top of the wing, and all aileron cables and pulleys have been mounted externally for the sake of simplicity, although the original intention was to place them inside the wings. The wing section used, by the way, is R.A.F. 15. The fuselage is of the flat-sided box type, with a light skeleton of spruce covered with ply-wood. The longerons are stop-chamfered between struts to approximately tri- angular section. There are no metal fittings in the main fuselage structure, the struts simply butting on to the lon- gerons as in the De Havilland " Moth." The deck of the fuselage is cambered in the ordinary way, but owing to the fact that it curves slightly in side view, some difficulty was experienced in applying the plywood panels, due to the fact that flat sheet can be bent over a cylinder but not over a barrel. The tail of the " Mayfly " is of fairly orthodox design, except for the fact that the rudder is placed wholly above the elevator, the latter being undivided. The rudder is of large area, and provided with a large horn balance. All FEBRUARY 17, 1927 control cables pass inside the fuselage, those from the elevator cranks straight into the stern, while the rudder cables run from the rudder cranks to other cranks on a vertical lay shaft placed inside the fin. From cranks on the lower end of this shaft the cables are taken to the rudder bar in the cockpits. The cockpits are roomy, and provided with dual controls, one of the " sticks " being removable. The Bristol " Cherub" is mounted on light sheet-steel brackets, built up to form four pyramids, one on each corner of the fuselage. The engine is very accessible, and further cowling may be added at a later date. The propeller is a Fairey-Reed of Duralumin, and was presented to the club by the Fairey Aviation Company. The petrol tanks are situated in the top centre-section. A simple undercarriage of steel tubing with built-on fairings is fitted with rubber cord shock absorbers. Altogether, the Halton H.A.C. 1 is a very creditable piece of work, and it is to be hoped that the machine may be able to take part in meetings and races during the coming summer, so that the boys who have helped to produce it may have at any rate that satisfaction.
