User commentsI made one of these in 1947. I was 10. It won the glider competition at the school I went to, Dane Court, Surrey.The head master Mr. Boys, was keen in this area and he helped me to build it.

This model was designed by Bill Dean (see the initials 'W.A.D' in the bottom left corner of the plan), though Albert Hatfull drew most or all of the plan. The span, incidentally, is usually quoted as 12 1/2 inches.

Thanks. Yes, the plan has both signatures on it. Let's go with Bill Dean, though. Ok, have ammended the designer for this one. Wingspan on Outerzone is an integer value field, so no fractions.

Hello, I have recently built this Spook Glider as I am fascinated with the challenge of tailless models, and particularily “vintage” designs [main pic, 003-005]. The trim exercise was something like a “pedagogical adventure”, but well tamed, the little Spook does indeed fly very well. I also wish to add: Finding the optimal launch technique is a crucial part of the learning package. This project has been highly enjoyable, and I’ve just started to build a second example, with a lighter grade of balsa, just to see if there is any further improvement potential.
All the best from Sweden,

* 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.
