About this Plan

Spinning Disc Saucer. Free flight rotating flying saucer model.

Quote: "It floats up weirdly with a peculiar ululating whine reminiscent of a flying saucer from a science-fiction movie. Then, moving through the air graceful as a gull it begins its descent and returns to earth gently as a feather. This novel project is sure to stop the show at any flying site.

Best of all it is easy to build, certain to give good results and it is probably the only model you'll ever construct that will fly right off the board with no adjustment whatsoever.

Begin by sketching out the 2 foot 12-sided disc on insulating board. Cover with waxed paper and locate the center hub, the rim pieces, and install the six spokes of the top. Add the stiff paper gussets and let the cement dry thoroughly. Make up the tubular paper spacer and the bottom hub. Cement these in place; add the other six spokes and gusset therm to the rim. Use plenty of cement; let it dry well and there will be no warps.

Cover the disk framework with medium weight gas model tissue. Water spray, to shrink, and when dry and tight give it a couple of coats of diluted butyrate dope. Pin down the disc while the dope is drying to prevent wrinkles or pulling out of shape.

The cabin is a simple dome-shaped structure of 1/8 sheet balsa formers with a 3/32 wire axle. Cover with stiff paper and dope any color that suits your fancy. The fin and the windows can be any shape since they do not affect performance and do provide a fine chance to individualize your model.

Make up the lifting vanes. Five are identical, except that one has a hole cut in it to allow for installation of solder ballast. The sixth vane, to which the engine is mounted, is different in shape because it is bolted directly to the framework. Note this vane operates flat - no pitch. The engine mount is a disk of plywood, pinned and cemented to the vane and backed up with a soft balsa fairing. It may vary with the engine used. Mark out and drill the mounting holes before installation. You'll need a good hot .049 size engine for best results. We used a Thimble Drone. Note that the motor is mounted at an angle so that fuel will continue to feed under the effects of centrifugal force. The propeller is mounted tangentally for most effective thrust..."

Notes

* 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.

Scaling

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.
