I/PGHT] SEPTEMBER 21, 1912. land, when fitted with them in addition to its floats. It is, perhaps, scarcely necessary to add that the model found no difficulty in accomplishing the converse or opposite task. Mr. Dean's Rule for Rubber Motors. Mr. F. Robinson (Hon. Sec. Folkestone Model Aero Club) writes re the above. Like Mr. Noorduyn, I can in no way agree with Mr. Dean and think that a hard-and-fast rule is impossible. May I quote one or two examples. C. Cornes flying on Saturday last in a dead calm, distances well over 250 yards, was using a 30-in. A-frame model with 9 ins. bent birch propellers and 9 strands a side of i, in. strip rubber. I have myself flown models over 300 yards using 6 strands a side of •& in. strip and 8 ins. propellers —the models weighing over 4 ozs. Replies in Brief. W. J. WILLIAMS.— Photos, &c., to hand and shall appear in due course. A. V. R.—Try a Bonn's 12 ins. centrale type propeller. From 16 tj 20 strands. K. A. RoimiNS.—Try a simple light iron (not brass) right angled bracket and fix it to the rod by well binding with thread, the bracket will not slip along the rod if the horizontal part be on the opposite side of the red. Use a piece of 18-gauge piano wire, sharpen one end, bend about | in. right round, so as to be parallel to the longer portion. Put the longer end through the hole in the boss. It must not fit loosely ; if it does, pack carefully with, say, copper-foil, then drive home, and convert exposed end of wire into usual hook. F. G. PETER.—We regret the drawings sent are not sufficiently clear for reproduction. Also, you give practically no details of your model; full details must be given. As you will see, an excellent example is given in our present issue. C. N. HAY.—Your span is somewhat large for your propeller diameter. The length of your fuselage depends on what ideas you may be endeavouring to carry out in your general design. It is really impossible to give a hard-and-fast answer to a question of this character. Your wheels must be ahead of your c. of g., or your model will tip forward ; or you can have one wheel well in front and two sufficiently far back to prevent the model from tipping back wards. As your model is single-propeller type, the latter is the better plan. Let the wheel-base be fairly large. C. W. TAYLOR.—Glycerine, if pure, is not a grease ; nor is it oily. Soda and water is all right if freshly applied ; try some Bragg- Smith lubricant. It should be, but everything depends on the efficiency of your machine. A special motor is not necessary ; a light steam engine would answer. Special motors are not easy to to make. ® ® ® ® THE KITE AND MODEL AEROPLANE ASSOCIATION, OFFICIAL British Model Records.

Competitions.—The two kite competitions which were to have been held on Saturday afternoon, on Wimbledon Common, had to be postponed »n account of the weather. Had the wind permitted, a most interesting contest would have taken place, for the competitors would have demonstrated the use to wbich they considered was the best a kite could be put to, and included wireless telegraphy, photography, ship-to-shore or life-line carrying, and signalling. However, the judges, at 4 o'clock, decided that no contest could Like place, and Major B. Baden- PowcII decided that this and the other contest for kites should take place on Saturday, Octobei 19th. Ornithopter Competition.—Entries for this competition should be sent in at once to the hon. secretary. Latest date for receiving, October 5th. Prize, £5, presented by Major B. Baden-Powell. The prize will be awarded to the designer of the model which, in the opinion of the judges, performs the best flight, travelling a distance of not less than too ft. through the air. The donor thinks that the principle of flapping wings is a mode of aerial propulsion which may p ove to be of greater efficiency than that obtainable by screw propellers, there fore has offered prize to see the principle tested in model form. Competitors NOTICES. should note that the prize is offered to the designer, therefore bought models are barred. Model Competition, at the 100-Acre Field, Greenford, September 28th, at 3 o'clock.
