Colossus V. Free flight competition model, from April 1949 Flying Models.
Quote: "Simple to construct and operate, this ship brings Class D Flying into the reach of most beginners. Colussus V, by Chuck Giessen.
After the cessation of hostilities and our return to civilian status, we were eager to get back into the model game. But, lo and behold, the picture had changed! There were different rules in effect. You might say that we were put right back into the beginner's class. We not only had to construct a model which would be able to compete with today's high-powered contest ship, but also one that would be stable and easy to handle.
To fill these requirements the Colossus was designed. Originally starting out life as a Torpedo-powered model, the Colossus was scaled both up and down to take a Madewell and a Mite. All versions performed very well. Then, with slight modifications, the Super-Cyke-powered Colossus V was evolved. Construction is extremely simple - even the beginner will experience no trouble - yet the structure is sturdy enough to withstand the toughest beating. Enough of this banter. Enlarge the plans to full size, unlimber your razor and sandpaper block, and let's begin construction.
FUSELAGE : First lay out the longerons on the/side view of the fuselage. Use a medium grade of wood for the upper longeron as this will take the bend better. It is advisable to make both sides at the same time to insure uniform-ity. Put all the uprights in place first and then the 3/16 square diagonals. Allow the structure to dry thoroughly.
Assemble the two sides by first cementing in place the two 3/16 sheet bulkheads, then tapering and cementing together the rear of the fuselage. Next cut the cross pieces to the length shown in the top view and cement in place. Then, the diagonals are put in..."

* 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.
