Quote: "Just because a beginner's model should be simple, build fast, and fly easily, does not mean it can't be stylish. Pogo, by Rick Rabe.

As the propellor picks up speed, the plane begins to move. In less than a foot, it is airborne and climbs almost vertically until the propeller stops turning. Instantly, the plane noses over and goes into a long gentle glide, finally touching down to a perfect landing.

Does that sound like the flight of some hard-to-build, expensive contest-type model ? It isn't. It's just a normal flight of the Pogo. The Pogo is not hard to build, nor is it expensive, or hard to fly. It requires a minimum of construction skills. An ideal beginners' project, the Pogo can be built in less than two hours and easily can be flown in the usual back yard. Wherever it is flown, its one-wheel landing gear, swept wing, and unusual tail arrangement will make it stand out from the ordinary beginner's plane.

Construction: The tools for building this plane are those usually found around the house. When buying the required balsa, select oat,. only the straightest strips. Check by looking down the edge to see whether Nate wing made on its covering material. later the extra tissue is cut away, the wing turned there are any bends in the strips. For help in selection, ask the hobby shop sales clerk. For the propeller assembly and wheels, purchase a North Pacific plane kit such as the Skeeter which sells for about 15 cents.

Lay the plans on a building board and tape the corners down. Place the covering tissue over the plans, making sure it is wrinkle-free, and also tape its corners down. The plans can be seen through the tissue.

Cut out all balsa parts as shown on the plans, but not directly over them, else the covering tissue may be slit accidentally. Use several light strokes instead of one heavy one for cutting. Check each piece to be sure it is the proper size.

Lay the parts for the wing and the tail in their places, Fasten the parts to the tissue and to each other with a thin layer of glue. Do not use too much glue because it will make the plane too heavy. The tissue, in a later step, will be used as a covering material.

When inserting the tail fins, have the photograph handy for checking their angle. Place one of the fins on the building board, but not on the tissue. Apply a line of glue along the base edge of the fin, Lay the other fin on top of the one on the board so that the bases are lined up. Slide the fin angle guides between the two fins (one in the front and one in the back) so that the bases are still together. Looking at the fins from the front, they should now look like a slanted V. Allow all parts to dry completely.

If using the North Pacific landing gear, bend it to the shape shown on the plans. If building the gear from basic parts, cut a piece of wire and bend it as shown on the plans. To build the wheel, cut out six 1-1/4 x 1-1/4 in balsa pieces from 1/32 sheet. Glue these pieces together, placing each one so that the grain runs opposite on each successive piece. When dry, sand to roundness and punch out the center with the landing gear wire, Attach the wheel and bend up the wire to keep the wheel on the wire. The parts are now ready to be assembled.

Assembly: Cut the tissue from around the wing and tail, trimming off any excess. Cut out the fuselage and glue the tail in place. Allow to dry, then glue the fin assembly in place. Lay the wing, with the tissue face up, on the building board, Gently break the wing in the center and bend up so that the dihedral guide will support the wing tip. Glue the center section so that the wing will keep the angle.

When the wing is dry, remove the guide and glue the wing onto the fuse-lage at the location shown. When the entire assembly has dried, insert the pin to hold the rubber, using glue to hold the pin firmly. Wrap the landing gear with thread for extra strength and glue in place. Slide the propeller assembly onto the front of the plane and attach the rubber loop.

Flying: Be sure the model balances as shown on the plan. Gently push the model forward at about shoulder height and release. It should glide straight forward and touch down about 12 to 15 ft in front of you. Wind the propeller about 50 turns and launch the plane as in the test glide, releasing first the prop then the plane. The model should turn in flight and touch down about 20 ft in front of you.

If the plane does not turn under power, bend the front part of the prop assembly. Try it again, this time winding it about 100 turns. The plane should climb gently to the right. If it stalls, bend the prop assembly a little more to the right. If it does not climb, straighten out the prop assembly a little by bending it gently to the left.

For long flights use a drill with a wire hook in the end of it to wind the rubber. For ROG (rise off ground) flights, wind the motor about 400 turns and release the plane on the ground. This type of flight will demonstrate the reason for this plane being called Pogo."
