AUNT AMELIA'S AERO CLUB

I The Robin Stretches His Wings This week we introduce the Robin, a special favourite of Aunt Amelia’s. He flies very well, and you will have no difficulty in making him if you follow these instructions and watch the diagram.

The Fuselage Cut a balsa stick measuring 3-16 in thick, lin wide, and 18|Hn long, lYou must round off the top-front fcorner, and sandpaper it till it is perfectly smooth. The Wing For the wing you will need a ?iece of sheet balsa l-16in thick, lin wide, and 20gin long. Cut it as shown in the diagram, sloping Wn-its full width at the middle to *be.curve shown on the graph at

each tip. Cut the wing down the middle, and set at |in dihedral, and cement the pieces together as shown. The Elevator The elevator is cut to shape from a piece of balsa l-16in thick, 2in wide, and 7Jin long. Draw the tip with a compass set at a 13-16 in radius, trace it on each end of the piece, and cut-them out. Be sure you get the same camber shown in the plan. Cut the elevator in half,

and set its tips for a 7-16 in dihedral, and cement together in thin position. Finish smooth with sandpaper. The Rudder The rudder must be cut from a piece of sheet balsa measuring l-16in thick, 2 l-16in wide, and 3jjin long. Metal Fittings With the exception of the propeller bearing, all metal parts are bent from No. 8 piano wire. All of these are shown full size in the plan. To allow the leading edge a the elevator to be higher than its trailing edge, an extra wing clip is used on the trailing, while the higher clip (the elevator clip) is applied to the leading edge. You will need three wing clips, one leading edge elevator clip, one nose hook, and "S" hook, and a propeller 'shaft. Bend all of these to shape.

The Propeller This is enrved from 3in thick, lin wide, and 85in long balsa propeller block. As the propeller is a pusher type, its shaft must be applied from the convex side of the blades. The Assembly Thrust the point of the nose hook in the end of the motor stick, and cement, firmly in place. Buy a small light propeller, and cement it in place ns shown in the plan. Cut

a l-16in wide and 2 l-16in long ;;lot in the top of the stick to hold Hie rudder. Cement this in place. Cement the wins clips to the under side of the wing directly over its cemented joint. The large elevator clip is cemented to the under side of the elevator over its joint 0:1 the leading edge, while the remaining wing clip is applied in the same position on its trailing edge. Slip the clips of both the wing and the elevator over the stick about the place shown in the plan. The Motor Get a length of Am flat rubber 72in long, tie its ends together, and assemble the "S" hook on the end hook and the propeller shaft through the propeller bearing. Loop the rubber twice over the "S" hook and the hook of the propeller shaft. The model must now be given the gliding test to determine the exact position of both the wing and the elevator. Wind the propeller and launch the model. A certain amount of slack has been allowed in the motor; this gives extra turns of the rubber. As this model is a pusher, the propeller must trail the model, and the elevator must lead.

"This parcel is too heavy," said Die postmaster to Sally. "You must put another stamp on it, dear." Sally looked very puzzled on hearing this. "But —but another stamp will make it heavier!" she declarod. —JOAN COMER.

Why is a black hen more clever than a white hen? Because a black hen can lay white eggs, but white hens cannot lay black eggs. —MAUREEN HARRISON, A. 8., L.8.H., Kirwee. Jessie June jumped jiggety jog-, gety jog. i —THERESA TAYLOK.
