About this Plan

Penaud's Planophore - Rubber sport model. An updated experimental version of the vintage Alphonse Penaud design.

Quote: - "1871 vs 1955. Suppose Penaud had balsa wood? Or modeling tissue? How, then, would his design compare with present day models? Very well, says this author...Intrigued by what we had read of Penaud, we undertook a novel experiment by constructing one of Penaud's rubber models to almost identical proportions and then constructing still another model of approximately the same proportions, but modifying it in accordance with present standard model airplane practice. We wanted to see just how performance of a present type model design would compare with that of one originally conceived 84 years ago. When completed, the models weighed .35oz. and .45oz. ready to fly, the lighter one being the Penaud. Of course the use of balsa and superfine tissue, while not used sparingly, still resulted in a lighter weight than Penaud could hope to achieve with the materials then at his disposal..."

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.
