Flying Wing (oz12871)
About this Plan
Flying Wing. Simple catapult glider model.
Quote: "Flying Wing. You can make this modernistic high flyer from a single sheet of balsa 24 x 2 x 1/16 in, and it will provide a lot of fun for a very small expenditure in time and cash.
The wings are built without any camber, but be sure you tilt the stabilizer a bit as shown. The tilt causes the model to circle, and as shown you'll get a right turn.
An iron washer was found about right to weight the nose; it is cemented on over the music wire hook and prevents the latter from pulling out on an extra-enthusiastic launch. False air intakes are added to the nose for appearance, and they also strengthen the wing-fuselage joint. The boundry-layer fences on the wings are also for appearance, but serve further to keep the wings from warping.
If you want top performance, keep the weight as low as possible by using soft wood, and as little clear dope as possible. Furthermore don't color-dope the craft. You can add a few decorations by means of decals and india-ink lines.
Test glides of the finished plane will show if the balance is right. Try to get as shallow a glide as possible, adjusting the balance by adding or subtracting bits of modeling clay stuck in the air intakes. The model will travel flat and fast when adjusted right.
Since the stab is set for a right turn, hold the model with the wings vertical, left wing uppermost, and nose slanted up a bit. A good launch will get her away to a large climbing turn, and she'll level off at the top with little loss of altitude, to continue the right turn in the glide.
Plans are printed half size, but you can make it the size shown by using 1/32 wood (and launch by hand or with a much smaller rubber loop). A glider this size makes an excellent 'quicky' to be built and flown at your model club meetings. Try it for some real fun.
And one last confession; that stab is really not needed, but was put there just to satisfy the builder who hasn't tackled a plane of such advanced configuration. If you leave it off, warp the inner trailing edge tips of the wings up about 1/16 in, and you'll find the plane flies just as well or even a little better than with the stab."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsI built this model some 60 years ago. I have the original magazine so it was an easy task. It flies beautifully. Who designed it? No mention is made but it is so easy to build and enjoy it is worth building even if your present job is making Goldberg's Valkyrie.

* 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.
