About this Plan
Contester. Simple rubber duration model. All-sheet design.
Quote: "Want to get up in the high-time category with minimum building effort? Here's a fine all-balsa, rubber-powered trainer that can give real contest per-formance and be built by a beginner. For best results proper choice of balsa is very important; medium-soft grade is used for all parts. If you are not experienced enough to select wood of this grade from the stack at your hobby shop, ask the dealer to or get a friend who knows models well to act as your 'picker.'
The fuselage is made from two identical sides, plus added 1/16 sheet for top and bottom. Grain of all four sides must run fore and aft as indicated. Easiest way to assemble is to cut the sides (make sure they are exactly alike), then cement the bottom to one and the top to the other. You will then have two L's which cement together. Before closing up the fuselage, note that reinforcement pieces of 1/16 sheet must go inside the L's at the point where the rubber dowel passes through, also at the nose. Grain of all reinforcement pieces should be at right angles to the length-wise sheet for greatest strength.
Carve the nose plug; make a hole through it for the prop shaft; cement washers (or pieces of thin plywood with drilled holes) front and back to act as shaft bearings. Note carefully that the thrustline is inclined downward; try to match the angle shown exactly since this downthrust assures stable flight under power. A notch is made in the plug for a rubber band; small hooks from music wire or bent pins are attached to the fuselage to hold the plug in place. A square of 1/2 in thick balsa cements to the rear of the plug to keep it from turning in the fuselage.
Your wing is cut from a sheet of 1/32 thick balsa; each half gets four ribs cemented to the underside. Pin down each half on a flat board with a sheet of wax paper between to keep any oozing cement from sticking. When fully dry, the center ends of each half (and the ribs cemented there) must be sanded till the ribs meet in a close fit with the proper dihedral. Note that 3 in dihedral is specified for each wing tip; thus, when the wing center is on your work board, each tip will be raised 3 in above the board. Cement the halves together (with each tip raised this much) and support with books..."

Maybe, maybe not, but I think the modeler posing in this photo looks a lot like Arthur Silberburg of Parlor Fly fame (oz3441).Tim Larson - 18/01/2023

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.
