Plate XI. Winding a model.
In order to wind a model remove the skeins from the anchor hooks and hook them on the winder. Have some one hold the machine at the rear end, slipping the fingers around the propellers to keep them from untwisting. Stretch the skeins out to about twice their normal length and commence to wind. Gradually shorten the skein as the winding progresses until, at the time it is finished, it is down to its normal length.
FIG. 56. A winder made from an egg beater.
In winding the machine be careful to do it in such a manner that the machine is not wrenched or twisted. Always count the number of turns given the winder so that there will be no danger of twisting them up too tightly and causing them to break.
The successful flying of a model aeroplane is an acquired knack just like swimming or bicycle riding. It is usually necessary to make several attempts before the model can be made to fly well. As soon as one gets acquainted with the vagaries of a model aeroplane it is a very easy matter to launch and adjust a machine.
The large page in the front of the book shows the right way of launching a model. The fingers are passed over the propellers and the frame grasped firmly, but gently. The tip of the machine should be raised and pointed slightly upward. Then give it a gentle slow push forward and release it. Always launch a machine into the wind, that is against it. The machine will fly forward, rise rapidly, turn completely around and race down the wind for a thousand feet or more in the case of some of the larger machines described in this book when properly adjusted.
All the models described in this book with the exception of the first three must be flown out of doors because, when properly handled, they will travel upwards of one thousand feet.
