Scoring:
Makes a straight, clean fold especially important
on cardboard.
1) Hold ruler VERY firmly where you want a
straight fold.
2) Press and run a scissors tip along the ruler edge.
3) Bend the cardboard along the scored line.
Use little pieces of scotch tape rather than long strips.
(1 inch strips or less) It’s easier to control short strips
and it saves tape. The strength of your ‘stickiness’ is
usually more a function of how well you clamp or press
the bond than it is the amount of tape or glue you use.
Use > marks when measuring. If you use ‘ marks,
your line is likely to be crooked.

Fuselage
Score length of
cardboard
¾” wide with
scissors.
Mark another ¾”
strip with a pencil.
Cut along the mark.
Should be 1.5” wide
by 11” long.
Scoring paper or cardboard makes it bend straight and clean. To score, hold
your ruler VERY firmly and run the tip of your scissors straight along the
the ruler edge.

Fuselage
Bend the cardboard
along the score line.
This will make a
pretty light but rigid
fuselage.
Wrap masking tape around
the nose. Cut a notch on
scored side.
NOT THE OPEN SIDE!
This ‘hook’ must be strong
enough to support a rubber
band sling shot launch.

Wings
From card stock
paper, mark a 5”
wide wing x 11”
long.
Score 1” from the
edge.
Bend the wing along
the score line.
This bend on the
front edge of your
wing will make it
stiff.
Cut a 1.25” strip for
the tail.
www.Build-It-Yourself.com
Tail
Cut a 2” slot in the
rear of the
fuselage for the
tail.
Bend the 1.5” wide
tail strip in the
middle.
www.Build-It-Yourself.com
Tail
Insert the tail piece in the
fuselage slot. The tail fin
should stick above the
fuselage about 1.5”.
Bend the tail wings out.
Tape the front end of the
tail fin so it cuts the air.
Cut the tail wings together
about 2” below the fuselage.
Wrap scotch tape around
the fuselage and tail to
secure it.

Mount wings (Optional step to increase strength)
This mount piece can help keep your wing perpendicular
to the fuselage.

Cut a cardboard
strip 3.75”x2”.
Score ½” wide
strips.

Bend the cardboard
to make a strong wing
mount. The “V”
section will fit in your
fuselage. The flaps
will be attached to
your wing.
Measure cut and bend elevator flaps.

Mount wings
Tape or hot glue
the front wing
edge to stiffen
the wing.
Mark the
center of your
wing. (5.5” on
each side.)
Tape your wing
to fuselage.
It usually glides better if the wing
is mounted very close to the tail.
You may want to
tape or hot glue
a cardboard
strip or coffee
stirrer stick to
keep the wing
extra stiff.

Cut and bend
elevator
flaps. 2”
from the
edges. 2”
long. ½” wide.
Test your glider
Before you launch your glider with the
rubber band sling shot, throw it gently to
see how well it glides.
You can control the center of gravity (so
your plane does not stall or dive) by
wrapping a rubber band around the front
of the fuselage. Adjust the position of
the rubber band until your glider flies
straight.
Wrap and tape some foam
rubber or a small paper strip
around the nose tip so your
plane won’t poke your eye out.
You can also adjust the wing elevators to
make your plane fly in a loop.
Two eyes are better than one!!!
