NOVEMBER 1, 1928 THE WESTLAND "WIZARD" SINGLE SEATER FIGHTER: Three-quarter rear view. patented features in their construction. They run from thelower longerons to the two wing spars, and are approximately parallel, so that bracing wires in the plane of the struts havebeen employed. The ailerons are hinged to " false " spars, and are of narrower chord at the root than at the tip. Theyare balanced by shielded horn balances and have been found very effective and light on the controls. The undercarriage is of normal type, with axle runningacross and the rear leg of each Vee being the telescopic member. The shock-absorbing gear in the " Wizard " isof the well-known Westland type, using a medium-pressure air chamber and oil dashpot with tapering needle valve. A tailplane trimming gear of somewhat unusual type isfitted. This is operated by a lever with ratchet stop, and is claimed to be much quicker in operation than the worm-wheeltype. The two petrol tanks, each with a capacity of 34 galls.(155 litres), are mounted in the wing, and the removal of the tanks is very simple as the bolts for the securing clampsare exposed on top and bottom of the wing, so that all that is necessary is to undo the nuts, when the tanks can be droppedout. Direct-gravity feed to the engine is used. The radiator is of the retractable type, and projects whenin the " out " position through the floor of the fuselage just behind the rear undercarriage struts. It has beenfound that this position has the double advantage of offering a minimum of drag and at the same time keeping the pilot'scockpit well heated. The " Office "The pilots cockpit is placed approximately in line with the trailing edge of the wing, and the seat is of such a height thatthe pilot's eyes are about level with the wing, enabling him to look either over or under the wing. The seat height isadjustable on the ground, and there are two positions of the rudder bar to suit different pilots.The two machine guns, one on each side, are placed with their feed and locks inside the cockpit and within easy reach,so that in the event of jamming or other non-functioning of the guns, the pilot can see and reach the locks and operatingmechanism of both guns without difficulty.
