About this Plan
Spinneroo. Free flight sport flying saucer model, for .8 cc engines.
Quote: "Weary of Wakefields? Tired of Team Race? Petulant about Power? Build this saucer for that spare 0.8cc glow, and enjoy some fun! Spinneroo by Ray Milland.
To Build the Spinneroo eight disc sectors needed, cut from stiff, fluted card about 1/16 in thick. Four sectors placed end to end make a circle (of sorts!) so staple and cyano two sets. Next you need a similar piece of card, 25 inches long and 2-3/4 inches wide. Score it vertically every three inches and bend it into an octagon. There will be a 'spare' inch; this is the overlap. Slits are cut as shown, alternately top and bottom.
The 'horns' of the top circle (that's the one with the arrows going clockwise) are glued into the top slits, and as you might expect, those of the bottom circle are fixed into the lower ones. The two circles are then brought together and stapled round the edges.
The engine mounting is from two 1-1/2 in diameter discs of one-eighth ply, both of which are pre-grooved on one side across the diameter. The engine bearer is a 14 swg wire cross, about an inch all round bigger than the card octagon. The two ply discs sandwich the cross and the wire is mounted in the octagon about 3/8 in from the bottom. Bend over the ends of the wire where they pierce the card and epoxy a small card reinforcement in place.
A 3/16 hole is drilled through the engine plate and a dowel is epoxied in place. An eye-dropper tank may then be rubber banded to the dowel. Finish and fuelproof to taste.
To launch your saucer, hold it from underneath by the engine plate. Walk - or run - downwind to match the airspeed, spin the saucer with the torque and release. Note: 'discus' or 'flick' launches will not work.
Now indulge in some saucery and terrify the earthlings!"

Quote: "Back in the early 80's I saw someone with a commercially produced flying saucer at Barkston. It went well but was quite overcomplicated and a bit fragile. I built a simplified version and flew it at Old Warden. It went surprisingly well and stayed in one piece.
Geoff from Aeromodeller asked me to draw up a plan, which I did, and here it is. I lost the relevant Aeromodeller years ago, but an ad in SAM Speaks got a couple of kind offers of the plan and here it is.
I haven't seen any of the corrugated card used in the build for years, but I reckon there are so many better materials around now for a successful build. Did I hear someone say 'electric'??

* 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.
