[fijCHf JANUARY 21, 1911. 34 ins., chord si ins. ; elevator, span 12 ins., chord 3£ ins. ; length overall 48 ins. The tractor is 10 ins., cut from a solid block. The machine will raise itself from the ground under favourable conditions. Heme Hill. L. WILLIAMS and M. PALMER. MODEL BIPLANE. (1032] I have just made a biplane of the new Cody type, 30 ins. wide and 24 ins. long from tail to elevator, and its weight is 7 ozs. IA pre.sent I nave a 'o-in. propeller, and 3 yds. of elastic | in. wide on it. The propeller revolves at 600 r.p.m., but this is not enough to drive it along. The distance from the propeller-shaft to the fiont of the elevator, where elastic is attached, is 12 ins. How can I increase the number of r.p.m. of the propeller to make it go? Does it want more elastic or a bigger drive, or would a couple of propellers be better than one ? Or is it because the elastic is not strong enough ? H. E. BATHO. [The best move would be to try two propellers ; they ought to give a better combined thrust than would be available from one screw with more elastic—ED.] ® <£ ® ® Mr. Grahame White's radiators, after his smash on Dover Cliffs towards the end of December, just as they reached the makers, the Spiral Tube Company. By means of tests they found there were five small leaks only, due to the points of screws in some wooden cross-pieces piercing a few tubes. NEW COMPANY REGISTERED.
