About this Plan

Shuttle 78. Radio control sailplane. Wingspan 78 in, wing area 819 sq in.

Quote: "The Shuttle is a Legionair kit designed for thermal or slope soaring. It has a wingspan of 78 inches and a wing area of 819 square inches. If you're in the market for a fast-building sailplane that combines uniqueness with perfor-mance, this plane is definitely the answer. The planform of the fuselage lends itself greatly to exciting color schemes. There are a few other things that are unusual in the construction. An example is the aluminum tube spar, a trademark of Legionair kits. It is an advantage because the wings are prac-tically unfoldable on a winch. We have done all the test flying of this airplane on a slope in fairly heavy winds, and have found it to be a very smooth and easy flier. We will tell more about the flight characteristics of the Shuttle after the construction part of this article.

We found a modification that is necessary in the fuselage. The fuselage construction is all plywood in front of the wing and an open stick framework aft of the wing. Unfortunately, the point where the plywood meets the stick framework is a high stress point. Unless you are an expert at soft landings in 20-knot winds, as I found I was not, some beefing-up is needed behind the last ply former. What we did was to splice in 1/4 by 1/8 plywood doublers to beef up the existing balsa longerons fore and aft of the last ply former.

The fuselage was easy and fun to build. You start by building up the sides as usual, doing the needed modification at this time. The disc sander from Stricks Enterprises came in extremely handy for joints and gussets. After the sides are done you simply drop the bulkheads into the notches in the sides, taking care that everything is square over the plans. I used 5-minute epoxy throughout the fuselage, since the strength is needed, especially in the open framework. I used Titebond only for the top and bottom balsa sheeting. After gluing the tail..."

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.
