Rick Rabe's rubber-powered free flight
"Pogo," not to be confused with Bob Morse's glow fuel-powered R/C 1/4 Midget racer "Pogo"
that appeared five months later in American Aircraft Modeler, is a quick-building
stick and tissue job for modelers of all ages and interests. Rabe adds a little pizzazz to
the craft with a "V" shaped vertical fin. The flat, stick-framed wing and stabilizer are
built directly on the Jap tissue, which speed the already minimal construction time.
Pogo
For the Tenderfoot

Just because a
beginner's model should be simple, build fast, and fly easily, does not mean it can't be stylish.
Pogo is fun for all modelers.
Aptly-named model climbs straight up, then flops into gentle glide when rubber unwinds.
Ready-to-use plans on back of centerfold.
As the propeller 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 .

Note wing made on its covering material. Later the extra tissue is cut
away, the wing turned over, and dihedral added. V-shaped rudders have built-on trim tabs.
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 only the straightest strips, Check by looking down the edge to
see whether 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.

Wind up the rubber band with a crank; hand drill is fine. Stretch rubber
and pack in the turns to a full row of knots.

Flight from a takeoff is most fun. Release prop first, then model, and
be sure to aim it into the wind. Pogo hops into the air.
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" 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 fuselage 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.

Basic tools for model airplane construction. Knife must be sharp and thin
for balsa.
