About this Plan

Jr's Pride (Junior's Pride). Hand launch glider. From the 'For the Tenderfoot' series.

Quote: "Very real-looking toss glider is all balsa and made from one sheet of wood. Junior's Pride, by Herb Clukey.

Off on the right foot? You bet! Success in the first venture of a young man's modeling career, whatever it might be, is most important. In model aviation, Jr's Pride can provide such success.

The little ship is built ultra light and with its cambered airfoil, a majestic slow floating-type glide is produced. All flights are hand launched and if you are fortunate enough to be near a nice up-wind slope, try a little slope soaring, as this gem has a glide ratio of 8:1 in calm air and will give you a lot of fun for the pennies invested.

Construction: In designing Jr's Pride, parts were kept to a minimum to facilitate construction. Cut out two fuselage sides, one each of No.1 and No.2 formers, one rudder, one stabilizer, two wing panels and four ribs. All parts are cut from one sheet of 1/32 x 3 x 36 in medium balsa. Nose block is one piece of 3/8 square balsa. Be sure to follow wood grain as indicated on drawing.

Glue fuselage sides directly to nose block and also glue No.1 in place. When dry, glue rear fuselage sides together, then add No.2. Check your work for alignment as you progress. Add top and bottom covering as illustrated in drawing. Cement stabilizer in place, then the rudder. The addition of a windshield is optional. Glue ribs as indicated in each wing panel. When dry, join panels together and prop up each tip 3/4 in. Cement wing to fuselage when dry.

Look at your Jr's Pride - it is finished and beautiful from any angle. Now let's preserve it with a coat of clear dope. When dry, sand with fine sand paper. This will cut down on surface drag and make the model more durable. Trim with color dope, but keep it to a minimum.

Flying: Now the real fun begins. Balance the baby by adding weight to the nose until a long floating glide is obtained. Trial and error is the best method. Remember that only a gentle toss is required. When ready, round up your pals and have an airplane 'ball game.' With a little practice you can stand about 30 feet apart and pass it to each other. The first one to drop it (it won't break) is 'out.' After this they might want to build their own Jr's Pride and have their own 'ball,' just as I am certainly having with mine - and I am a 45-year-old Junior!"

Quote: "I built one of these as a kid, had it trimmed in a few flights, then promptly lost it in a very mild thermal."

Hi, Steve. A few weeks back I found myself with nothing to do on a cold and windy afternoon, so I knocked out a pair of Jr’s Pride gliders. Since it’s rare for me to leave anything alone, I decided to make things interesting by scaling the plan up 200%, giving the airplane a 30” span. For material, I simply doubled everything to 1/16” balsa sheet. Just gluing bits of balsa together always makes for a fun afternoon, and I had both gliders assembled in about four hours. Four coats of thinned nitrate dope sealed everything up. When the first nice spring day presented itself in southern California, I headed over to the local schoolyard for some glides over the football pitch. As was expected with any model using an under cambered airfoil, the L/D wasn’t all that great due to poor wind penetration, but the low sink rate made up for than deficiency. If I were to do it again, I would reduce camber or use a Jedelsky airfoil, simply because the all-sheet construction is prone to warping. In any event, the models didn’t disappoint and it’s been fun getting back to the simple pleasure of watching a model float across the field without any interference from its builder.

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.
