Kewpie (oz14078)

About this Plan

Kewpie. Simple rubber sport model.

Quote: "HERE is a little skyrocket that will give you hours of fun and excitement. Its design came about one evening at about nine o'clock, the night before a weekly meet held in the auditorium of the school the author attends. In need of a simple design for a speedy assembly, this original was turned out. Came the clay of the contest, the model was finished, but it looked like somiething the cat had dragged in.

Its first flights were not worth the time wasted in taking them, due to the fact the ship was underpowered. A few more strands of rubber - then came the surprise. The model showed a fast climb, getting upstairs in a hurry and doing a little ceiling-scraping. The total time on that flight was 45 seconds, which is about average for Kewpie, but more is possible with careful adjusting.

A novel feature about Kewpie is its 'V' tail. We chose this because of its simplicity and the corresponding decrease in weight. The two-place dihedral also seems to help along with stability.

You should have no trouble in making this ship. The stock used throughout is soft 1/16 square, available at any model shop. The fuselage sides are constructed first, over the full-size plan marked 'side view.' Allow the cement enough time to dry thoroughly, then lift both sides off the plan. Cut top and bottom cross-braces to length required and assemble both sides. This part of the coontruction is tedious but necessary.

A piece of 1/16 square is used for the tail boom. It should be 3-1/2 in long. Note that it is assembled to the fuselage at a slight angle to provide the necessary angular difference between wing and tail. Assemble the stabilizer, then cover the entire model with superfine tissue.

The wheels should be cut from 1/32 or 1/16 hill a and mounted on the landing gear axles. The struts should he splayed out to obtain a tread of about 3 in. When assembling the wing, and mounting it on the wing struts, be sure not to use large globs of cement, as that will cause warpage and unnecessaary weight.

The power is six strands (3 loops) of 1/16 brown rubber. For slower and longer flights use four strands. Under power the ship circles sharply to the left and should have about four degrees down-thrust to overcome stalling tendencies under the initial burst of power. If you can't use the local auditorium, fly Kewpie outdoors, as she's a rugged little ship. Happy landings!"
