[504] I have built a model monoplane of 5 ft. span, with a total lifting surface of 6\ sq. ft., weight I \ lbs. Could you or any of your readers tell me the weight this model will carry to fly well ? Could I use an electric motor ? If so, where obtainable ? Hillhead. J. WATSON. ELASTIC MOTOR. [5°5] I think it would be very interesting to know the record thrust for weight of a rubber motor. Number of revolutions to be not less than 150. I wonder who can beat this. I have a motor 24 ins. long, giving 150 revolutions, weighing complete with propeller 5 ozs., that gives a thrust of 8 ozs. Hoping you can find room to insert this in the columns of your excellent paper. Balham, S.W. S. FAULKNER. ® ® ® ® A Dirigible in a Music Hall. THERE is no accounting for popular taste in the matter of public entertainment, but we must confess one would scarcely expect to witness the spectacle of a fairly big model dirigible sailing about the auditorium of the London Hippodrome, where at the moment it constitutes one of the star turns. The dirigible in question is fitted up with wireless control, and the operator, Mr. Raymond Phillips, makes it travel where he will, more or less, by the diligent rapping of an electric key on the stage. There is much crackling of electrical discharge, followed by the setting in motion of one or other of the various propellers with which the car of the dirigible is equipped. Two propellers on a pivoted cross-beam control the direction, while other two mounted on vertical shafts control the altitude. The little electric motors that drive the propellers obtain their energy from a small battery of cells, which are switched into action by a device that is sensitive to the wireless electric waves. As an indication of a phase of aeronautics that is quite likely, indeed, we may as well say quite certain, to figure in the future, this display at the Hippodrome is a thoroughly interesting and instruc tive turn, and brings before many hundreds of people a visual demonstration of a scientific subject that in the ordinary course of events they would only be likely to read about at the best. The mere fact that they have seen a model dirigible controlled without wires will enable theni to take a little more personal interest in the real thing when it comes, and if this sort of show proves popular for any length of time we shall really become quite an intellectual race.
