WM\ " The tail dimensions are lost, but it was of a fish tail shape wkh a vertical rudder half above and half below the apex of the rear edge of the tail. The leading edge was of triangular sectioned bamboo, and was hinged to the motor rod, in connection with the automatic stabiliser. Thus was worked by a wire running on grooved wheels fixed to the motor rod and connected from the rear edge of the tail to the sliding weight under the plane and motor rod. The idea beini that when the model pitched, the weight would slide forward and lift the tail from the back edge, depressing the rear part of the machine ai.d ihrowing the nose, up and thus enabling the model to recover its longitudinal balance. For want of time the tests with respect to this particular device were never properly carried out. The vertical i udder was also hinged, and could be moved either to the right or left for directional control, "The tractor screws were 13 ins. in diameter ; right and left hand pitch. The blade tips were at an angle of 45° to the boss of the screws. The design is better understood from the drawings. The leading edge was straight from tip to tip. The rear edge was straight from the tip till near the boss of the screw, which was cylindrical, and then was shaped like a scoop. The method of mounting the screws to the cross-bar of the motor rod was by continuing the motor shaft through a hole drilled in the cross-bar. A little nut was soldei ed to prevent the shaft from comir g out of the cross-bar, and washers were inserted between the nut and the cross bar to minimise friction caused by the pull of the rubber motors. This method of screw mounting (to my idea) reduces the friction to a minimum." ® ® ® ® KITE AND MODEL AEROPLANE ASSOCIATION. Official Notices. British Model Records. J. E. Louch K.
