About this Plan

Dunne Tailess. A 37.5in span FF virtually crashproof biplane tailess.

Quote: "An ultra-simple model with flat plate wings and a unique plan form, for any engine up to '8c.c. Will fly in any weather - virtually crash proof. The Dunne Tailless, by H.E Males.

No CLAIM COULD ever be made for this unique flying wing biplane to be a scale model, yet its outline closely resembles that of one of the most outstanding aircraft designs of all time J. W. Dunne experimented with tailless gliders having large sweepback, in 1905/6. In 1913 he demonstrated an absolutely inherently stable machine with a 7-cylinder rotary enigne, and remarkable though it was, official interest did not rise to the occasion.

It was with the fame of the Dunne types in mind, that HE Males decided to make this simple sport flier for an Allbon Dart. What could possibly be more simple? There are no ribs to cut, the washout required for auto-stability is locked in place by interplane fins, and being a pusher, it is virtually damage free as the wings knock-off in pairs.

It is cheap to make, will fly in all weathers, and collects a crowd wherever it appears. So if you want to knock up something to shake the locals, try the Dunne and you'll never regret the few shillings it costs to make.

Start building with the fuselage which is little more than a 'bath tub', having a block bow and engine mount in the stern. Two basic 1/8 in square sides are made over the plan and faced by sheets of balsa on the respective outsides. Add ply gusset for tank mounting on port side, the scrap supports for the engine mount, and cut and re-inforce the wing tongue slots. Join sides with the engine mount, undercarriage block, the 1/8 in sheet bulkhead which fills the rear end of the fuselage, and front top formers and spacers. Add all other spacers, stringers and noseblock, drilling the latter for the dowel to take the nose skid..."

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.
