About this Plan

Sharpie - Free flight sport model. All-sheet design.

Quote: "By Ken Willard. An all-balsa free flight model for Half-A engines. Proved performance makes it an ideal sport job and, incidentally, for beginners. The basic idea underlying the design of Sharpie was to come up with a sport flier that would be very simple to build, yet have pleasing lines and good performance. The all-balsa construction certainly makes it simple enough, and the curved sheet wing, already proven on the Pelican, gives very satisfactory climb and glide characteristics. The added feature of the tapered trailing edge, which results in built-in washout, makes a very stable arrangement. As for appearance, it speaks for itself, and the name came from the remark of a friend, who, on seeing the model for the first time, remarked: 'That's a real sharpie!' The name struck. Another friend, Bill Glick, liked the lines and performance so much that we scaled up the plans and he built an RC version, which has proved equally successful. The only change in layout was a reduction in the fin area relative to wing area. Construction of Sharpie is so easy that a brief study of the plans is about all the instruction that is needed. The following short outline may clear up one or two points on procedure for the beginner..." Ken Willard's Sharpie from MAN magazine issue 02-55.

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.
