JULY I, 1911. I/IIGHT| MODELS. Model Duration Records. [1244] I read in Mr. Grimmer's article on the Mann monoplane (FLIGHT NO. 129) that this machine holds the world's record for duration. May I state that it is not so, for I timed my friend's model, D. Holmes, for three flights, and the results were as follows : 1st flight 75 sees., 2nd flight 77 sees., and the 3rd 80 sees. All these flights were made by an elastic-driven machine on June 23rd. Thames Ditton. C. RIDLEY. Model Construction. [1245] With regard to Mr. P. Vere's letter (No. 1,021) asking how I made the planes of my models, and how single-screw models can be stopped from overturning, the following sketches will, perhaps, help him out of the difficulty. The framework can be made of piano-wire bound with fine floral wire and soldered, using as little solder as possible. Fig. I shows a very neat piano-wire bracket for fixing the planes on to the body. A small band of elastic is just slipped round the stick and bracket to keep it in place until the proper position is found. If piano-wire is not obtainable cane can be used instead, and the fabric fixed on as in the sketch below. When finished small strips FRONT SPAR -jat FIG r should be stuck over the ribs to avoid sharp edges, and the whole brushed over with paste to stiffen it. As to fitting propeller-shafts at an angle to each other I do not think it makes much difference. I make them because it is much easier to construct. I have made and experimented with small models, a la Clarke tail first type, and to stop them from capsizing I build them with a dihedral angle, small propeller, and thin elastic. If the other type, a la Bleriot, is built, a large tractor-screw will not upset it, but a dihedral angle and rudder is essential. Coventry. L. G. RYLEY. The Baxter Model. [1246] In answer to Mr. Horner's letter (1108) for working drawings of my miniature models. The articles required for con- .V 't* X £<qu»re sheet of thin tin for propellers, which will cost id. or 3d. The rubber was out of an old golf ball, £ in. strip. These articles will make about twenty models. I think from the diagram which is- enclosed he should be able to make it. I gave a demonstration to the scholars of Belle Vue School, Leeds, last year with these models, which were flown in the class-room. Leeds. L. BAXTER. [1247] A Model Farman. I send you two photographs of a model Farman, which. may be of interest to your readers, now in course of construction. Burton-on-Trent. The engine and propeller are C. O. HAYWARD. Twisting Tail Control. [1248] In reference to Mr. Ridley's letter (1199). it may interest him to know that I am making a model which, when completed, will have a twisting tail, and like him I thought I must be original, as I had not heard of this device being brought into use before. I thought there must be some device for balancing other than those which are the cause of certain legal proceedings in France, so I took particular notice of birds and found that they twist their tails both for steering and balancing, and I wonder that the method has not been taken up before. I am not surprised that Mr. Ridhy found it very efficient on his glider. I should like to hear of experiments with a full-sized aeroplane ; I think there would be no need for balancing tips or warping planes. Redhill. W. H. NORTON. Propeller Mounting. [1249] Replying to letter 1098. Use two propellers revolving in opposite directions for a model of this size in order to avoid twisting BRASS STBIP- SOLDERED TO SPORE NIPPLE BRASS PLATE t-.E.BlCrl^RDS SPOKE. NIPPLE FLM-SIBE F1T6 AGAINST 6RASS STQiP struction are : Florist's wire, id. reel; fine tissue paper, four sheets, la. ; 25 post-cards, id. ; seccotine, 6d. ; 360 steel pins, id. ; a the frame and also as a means of obtaining adequate thrust throughout a long flight. Use A in. square section elastic. Mount the propeller as shown in the sketch. The device consists of a bicycle spoke cut to required length, threaded at one end and curled into a S79
