l/l'G"Tl MODELS. Aeroplane Design. [IX33J I should be greatly obliged if you would allow me the use of your very valuable space to enable me to ask your readers their opinions with regard to the following questions. The first is, what is the advantage of the long fuselage over a short one or vice versa. I have an idea that a long one tends to make a model more stable longitudinally, owing to there being more length to correct fore and aft oscilla tions. Possibly I may be labouring under a false impression, in any case I am open to criticism. The next question I have to ask is, is there a special rule for the proportion of the small plane to the main-plane with regard to length, that is to say, if I construct say a plane 14 ins. long, what ratio should the length of the leading plane be, in the case of tail-first model, the aspect ratio being full 7 to I ? Having already written at greater length than I at first intended, I should like in closing to thank Mr. Bath (letter No. 607) for his recipe for paste, which is very good and I find that it keeps well. I also thank Mr. Neve for his letter re paper gliders, which are very satisfactory. Mr. Grimmer's article in your issue of December 31st re School Aero Clubs, I think is excellent. Stony Stratford. O. HAMILTON. [Will our correspondent kindly use span or chord instead of the term length when referring to planes.—ED.] Model Cody. JII34] I have pleasure in sending you a photo of a model of Mr. Cody's biplane which I have made and flown. I have to thank your paper for some of the chief dimensions. The machine is built of split cane joined with thread and braced with wire. I am experiencing some trouble with the motor. I cannot get the elastic to hold lor any length of time. Perhaps one of your readers would be good enough to give some advice. Westcliff-on-Sea. RIVERS SHERMAN. I "351 ^ A Tailless Paper Glider. am enclosing you a sketch of a tailless paper glider which I find is a very speedy and steady kind. One peculiarity in it is that the plane is set at an inverted dihedral angle, with aerocurved tips on the extremi ties of the plane. This can be made out of a sheet of note - paper and some flower- wire. This model has travelled a con siderable distance on a perfectly even keel. The steering is brought about by The planes have slightly an inverted Ruodei* J3 a small rudder behind. aerocurve, but the tips are brought down a little. Thames Ditton. C. B. RIDLEY. flodels.
