Gentle Lady - RC sailplane.
Quote: - "As a novice glider pilot. Carl wanted a two meter ship that was respectably efficient, and, if possible, competition worthy. RCM feels the Gentle Lady meets that criteria - Like most people who like airplanes, I've always been drawn to sailplanes. They are the most beautiful of man made birds. Their sleek lines, high aspect ratio wings, utter cleanliness, and refinement ot detail make them the ultimate 'clean machine.' At the Toledo Weak Signals show each year, I have to stop, study, and admire the very appealing sailplanes that are always on view.
Naturally enough, when thinking of designing one myself, I studied some of the better known ships around. Among them were the Pierce Arrow, Wanderer, Soar Birdi, Drifter II, and others. One of these was a fine East Coast design by Woody Blanchard, which has done well there. In addition, I spent many hours talking to glider flyers, reading magazine articles, newsletter reports, etc. There was a lot to learn.
Totalling things out, this is the design philosophy that emerged. First of all. I decided I wanted a two meter ship. The essential reason for this was a desire for simplicity. Getting into one of the larger birds, I felt, would tend to draw me into complications. They just naturally tend to be a little more sophisticated. Also. I had noticed growing general interest in the two-meter class. Interestingly, I later learned that the Dassel, the Austrian design that has aroused such great interest world wide, and which was used by the new world champion. Anton Wackerle, has only about 6in more span.
Besides simplicity, I wanted the ship to be easy to fly, and stable. Obviously, as a novice glider pilot, I didn't want to shoot for more efficiency through means that might require some real flight skills.
At the same time, I definitely wanted a ship that was respectably efficient, and, if possible, competition worthy. One major means of achieving the efficiency sought, based on past experience, was to use a thin airfoil, and build it with a smooth top. The lift-drag ratios of such airfoils tend to be quite high, and it turns out the Gentle Lady can really 'cruise' when desired..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
