About this Plan

Two Tube. Control line sport model. For .049 power. Two Tube Novelty 1/2a UC uses two paper towel tubes. D Mowrer, MAN April 1965. Can be built as a twin engined model.

Quote: "One of every modeler's ambitions sooner or later is to go 'multi' but constructing one fuselage is more than enough work for the average builder. Who wants to build two? This problem is easily solved by the creative use of a tube insert around which Christmas wrapping paper is usually rolled. Cut it in half, punch a couple of holes, slip in the balsa parts, and you've built a multi quicker than any single engine profile. Not only does simplicity characterize the Two-Tube, but versatility is an added feature that permits you to fly a single engine version, not to speak of a trimotor set-up. Construction is so simple that it falls together like a five-year-old's picture puzzle.

Construction. Wing and Fuselage. Begin by cutting ten identical wing ribs from 1/16 sheet balsa. Drill holes for lead-outs and center spar. Mark the rib locations on the 3/16 hardwood dowel and slip on the four inside ribs. Cut a 26 inch long wrapping tube in half and carefully drill the slots for the dowel spar, leading edge and trailing edge. Once this is done, slide the tubes on either side of the four center ribs. Then slide the leading edge and trailing through the fuselage slots and add the outside wing ribs. Center all ribs, taking care that there are no obvious warps, pin ribs where necessary and glue.

Next, glue on the top and bottom 1/2 inch square wing struts. The bathroom tissue tube can now be added to the wing center section by cutting two slits in the tube so it can be fitted over and glued to the leading edge..."

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.
