About this Plan

Sweet Sixteenth. Free flight power model.

Quote: "Any one-sixteenth sheet balsa around? That's all you need to turn out this pretty baby; and once built she's warp-proof. Sweet Sixteenth, by Aubrey Kochman.

Sweet Sixteenth, though fairly conventional as far as plyon model design goes, offers a different approach construction-wise since practically the entire model is built of 1/16 thick sheet balsa. This type construction, aside from being exceptionally simple and fast, results in a warp-resistant ship which when once adjusted to a definite flight pattern, will consistently fly this same pattern so long as the engine speed and propeller are not changed.

Selection of the 1/16 sheet stock is very important and great care should be taken to insure a light yet sturdy model. It is best to use 6 inch sheet stock for the wings and stabilizer, but if not available or for sweet economy's sake you can use 3 in wood. Select sheets of uniform weight and grain, medium soft and straight grain being best. Two sheets of 1/16 x 3 x 36 in preferably quarter-grained are ample for the fuselage, ribs, rudder, sub rudders, wing platform and the stabilizer platform. The plyon covering sheets can be cut from the same sheets used for the stabilizer. No difficulty should be encountered during construction if the following procedure is followed.

Build the wings, stabilizer and fuselage in that order as the wings require the longest drying time. The wing is built in four separate panels. Cut out the four sheets that form the bottom sheet covering, using a metal right triangle if possible to insure squareness. Note that the chord is under 6 in. The top sheeting, however, should be left oversize to allow for the bend. Mark off the rib locations and cement the ribs in place. Tilt the end ribs in slightly to approximate the proper dihedral angle. The exact angle is sanded in when joining the four panels. Further construction details will be found on AT full-size plans."

* 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.
