Flying Wheel. Jetex powered flying saucer model.
Quote: "The flying saucer idea takes a new turn. Flying Wheel, by Paul del Gatto.
EVER since flying saucers became front page material for newspapers, our interest in them has steadily increased. Within the last few years we've built and flown no less than half a dozen saucer configurations, both F/F and C/L.
For the most part these designs were very successful, but even when successful we never got the feeling that we had really achieved something unique in model aircraft. The reason we felt this way was because we had not simulated what might be envisioned as a true flying saucer. Our previous designs were all propeller driven by either an engine or rubber motor with but one exception, which was powered by a Jetex 50 unit externally mounted.
The latter design most closely approached our recent endeavour with but one very important exception. While our past designs derived their lift through forward motion, our recent endeavour derives its lift through rotary motion.
When the Jetex fuses are ignited the model begins to rotate and in a matter of seconds begins its ascent. The upward journey continues for approximately eight seconds, continually accelerating until the power is expended and the model is about 150 to 200 ft in the air. Approximately five to six seconds are expended in accelerating for takeoff. Coming down, the model spins in the reverse direction until it finally settles down to earth.
While construction of the model differs from that of conventional models, it is nonetheless very easy. The most important things to bear in mind is correct alignment of all parts and a light but strong framework.
To begin construction, start by cutting out all the required parts, taking care that the correct texture of wood is used throughout. The inner and outer rims are then pinned in place on the plan. If you experience difficulty in bending it to the circular shape, it is advisable to soak the wood in warm water and pre-bend to the approximate shape.
Next, construct the four bladed propeller and cement the 1/32 in sheet disc to the propeller hub; the remainder of the disc to be located after it is removed from the plan.
Locating and cementing the vanes in position requires the maximum amount of effort and care. Begin at any position and cement them in place in a clockwise direction with the correct helical twist..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
