Skua. All-sheet balsa soarer, for towline or hi-start launches.
Quote: "Full-scale glider lines are the feature of this 'bird' which flies or builds up solid. Skua, by Hank Dillenkofer.
Scale towline gliders are a rarity on the flying field and the principle reason for this is that most of them are so complicated to build. We found that we were a little lazy and didn't want to make a super-sized model that spanned some 6 feet and yet we wanted something that looked like the full-scale soarers seen on the gliding slopes all over the world. Our compromise was this small all-balsa model.
As a sidelight, we found that the model had all of the appearance of a solid scale model, too. We have ours hanging in our workshop as a show piece and it draws attention from visiting modellers. You might find that this ship suits you only as a solid scale ship.
Don't consider this as slighting the model's flying performance. We found that it soars as well as any hand-launch glider, has all the fun of a tow-line glider and is a sensation on high-start tow. It fits well on small fields and affords many hours of sport flying
during evening hours. Beware - if a sly thermal comes cruising by you can be sure that this model will prove itself the sailplane it professes to be.
CONSTRUCTION: Start by making the wing panels. These are cut in the same manner as handlaunch glider wings and are sanded to airfoil shape as indicated. Taper the wings toward the tips so that they are thin and flex uniformly. Jack up each wing tip 2 in to get the proper dihedral... "

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.
