fLJcm MODELS. Penaud and latin,;Models. [1194] »*I was much interested recently when looking through a boo't " named "Scientific Recreations" (published by Ward Lock and Co. in 1883), to find a chapter devoted to model aeroplanes. A certain M. I'enaud constructed a model which we are told would fly for a distance of 70 yards and remain in the air for 13 -econds. It is evident that this model was not correctly adjusted for " the various oscillations like those of sparrows or more especially woodpeckers can be plainly observed." .Another Frenchman, M. Tatin, constructed a model of the M. Penaud's model. M. Tatin's ornithopter. ornithopter type which was a success. It was found necessary in this model to have the centre of gravity well forward. A full size machine, however, was not successful. I enclose sketches of both models which it will be observed were driven by twisted elastic. Cardiff. HAROLD BEER. [Penaud was the inventor of the elastic driven toy aeroplane. —El).] MAY 27, 1911. iust slung inside the fuselage by strings. In this model I found that when Pleading edge was actually lower than the trailing edge, it flew further than when the position was reversed. Out of many models which I have made this one flew best, looked best, and cost least. „ • _ Thanet Street. GUY T. TAYLOR. ® ® ® ® NEW COMPANY REGISTERED.

CAFFYN. Models and the Dipping Edge. [1196] I have read with growing interest the many discussions in your interesting paper on the "dipping edge." It is quite possible to make a really good model for sixpence, and at the same time study the dipping edge very easily. All that is required is some stiff cartridge paper, seccotine, and a light elastic motor on a stick. Fold a 1 ft. length of the paper in the shape of an elongated cone, as in the Bleriot fuselage, cut the ends square, and take pieces out of top and bottom to relieve wind pressure. Next cut a long slit in either side, A B, 6 ins. long. Next cut out the wings, same as ordinary BWriot, 14 ins. long and 4 ins. deep. Insert through slit, A B. Mow there will be two inches in which the wings can move freely, and so alter the camber. Tail and rudder are inserted in slits, C D, E F, for rudder. The motor is British General Events.
