About this Plan

Sophisticated Lady HLG. Chuck glider model.

Quote: "It is no secret that hand-launched gliders can prove to be one of the most interesting forms of model aviation. And, to an experimenter like myself, they can almost be-come an obsession. What other type of model lends itself so naturally to variations in moment arms, stabilizer area, airfoil, etc. Because of the method of constructing a hand-launched glider, many design changes can be performed right on the flying field using nothing but a modeling knife and quick drying glue. Of course, the comparatively low cost of a hand-launched glider makes it much easier to discard a design than a more expensive type model.

It was because of this ease of change and my constant urge to experiment that Sophisticated Lady evolved. I use the word 'evolved' rather than 'designed' because that is exactly how it came about. The ship evolved from a long line of ancestors, each tested then discarded with its good points passed on to the ensuing heirs. The present result (notice that I did not say final result) of this testing is the Lady. A real blue blood, she has enough stability to recover from a bad throw, and a nose for thermals that keeps her upstairs a long time. I remember building a Lady a week for four weeks prior to a contest, then watching them all disappear into the bottom of a cumulus cloud while testing before the contest.

But enough about design. Let's build her and go flying. Perhaps the most important and difficult part of a hand-launched glider is its wings. Let's start there. It is made from a piece of very light balsa. You should be very selective in choosing the wood for this component. Both weight and straightness must be considered. A perfect wing can not be made from warped balsa..."

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.
