Peanut Scale

Wingspan 13”

Power Rubber

By WALT MOONEY

. Under a 25-foot ceiling it has so far proven itself a failure. It has given a top duration of 56 seconds, and has on about ten occasions flown for duration of 53 seconds. Part of the reason is that it is heavier than necessary. With the dummy plastic cylinders and the aluminium tube exhaust ring, it turned out slightly nose heavy and had to have a little clay ballast at the tail skid to achieve the centre of gravity position indicated on the plans. As a consequence, without the rubber motor, it was flown at a weight of 11.5 grams. The best motor was a twenty-inch loop of 2.5 millimetre rubber. About 2100 turns can be put in this motor. With a little care in the structure, and (maybe) soda straw cylinders, this model might be able to break a minute, but the
one in the photos hasn't been able to do it so far.

The Elias firm built several airplanes, none of which were very successful. The little "Aircoupe" however, looks like a good design for model flying. The model in this article was rather simple to
build and to trim out for flight. It flies in smooth left circles and is stable enough to recover from disturbances.

The construction of this model follows standard practice in all respects and should present no problems to anyone who has built a few models before.
