L/EI span, 48 ins., width where they join body 10 ins., tapering to 7 ins. at tips; tail plane, 15 ins. wide, 18 ins. long ; elevator, 6 ins. long ; length overall, 44 ins. The tail is made slightly bigger than the given scale measure ments, as I find this helps lateral stability. Sincerely hoping you will find space to record my humble efforts in your splendid paper. Luton. H. MANN. PAPER GLIDERS, A HEAVY WEIGHT MODEL, AND A MODEL CLUB FOR KINGSTON AND DISTRICT. [967] Might I take up a few lines of your most valuable paper with regard to the above heading. I have been experimenting with paper gliders now and then in my spare time for above a year, and I am sure they have proved most interesting and instructive to me. My best glides have been obtained by causing my gliders to circle round when there is a light breeze blowing. My latest glider went no less than some 70 or 80 yards in this way, at the same time rising about 20 yards in height. I am enclosing a small sketch of this little beauty, together with several more of my most successful designs, all of which have an average gliding angle when in trim of .-6----) ><b^ * .-5--- »--4--». one in fifteen. I find that a good method of weighting them is with a heavy pin, for one can thus adjust the weight by slipping it back wards and forwards, and I think this method is far better than using sealing wax or plastesine. I have now made about sixty small model aeroplanes, chiefly for experimental purposes. Some of these have worked out at i| lbs. to the square foot when not loaded. One of these carried besides itself a weight of about three ounces ; the span and length of this model was but 23 ins., while the surface amounted to 50 square inches. When fully loaded this model did a flight of 40 yards. Myself and my friend, A. H. Weeks, have lately started a model club, especially for boys, in this district, and would all those interested kindly send me a post-card. Wishing every success to your most excellent paper, which has often proved useful to me. C. MENZIES, Hon. Sec. 36, Cromwell Road, Kingston-on-Thames. THE DUNN MODEL. [968] Replying to letter No. 809 of Mr. Goudie. I obtained the elastic and ball-bearing thrust from A. W. Gamage and Co. The fabric can be had at any linen-draper's. The small screw-eyes came from T. W. K. Clarke and Co. The wood and nails I got from "Hobbies, Ltd.," and the size and varnish can be had from any oil-shop. Camberwell. HENRY W. DUNN. CAMBERING PLANES. [969] Perhaps some of your readers have found some difficulty in cambering their models' planes. I found the following way answered well:— Get some ordinary model-making cane and cut into strips the required length. Having done this, split them down the middle and steam them into the desired camber. Then they can be stuck on to the spars of the plane and the fabric pasted over. It is best to tie them into position after steaming, and leave them until stiff; the string can then be taken off. Birmingham. R. G. PlNNOCK. ® ® ® ® PUBLICATIONS RECEIVED.
