Elmers Glue-All is the only glue I recommend for this rocket.
Yellow glue will not work as well because it shrinks too much and is
visible when it dries.
The
rocket
as shown is made from a 6" x 6" x 5" Priority Mail box which I happen
to have laying around. You may subsititute any other similar
corrigated cardboard box that is at least as big. This is a
version of my Stealth
design that uses corrigated cardboard instead of
foam-backed posterboard for the main components. It
uses a very reliable autorotation (helicopter) recovery
technique for recovery. It flies straight. low and lands close to
the
pad. It rotates on both ascent and descent. It's maiden
flight was at NSL 2006 where it wowwed the crowd. It flys great
on on Ellis Mountain G35 and Roadrunner G80-4 single use motors.

Lay the box down flat and cut just to the right of the overlapped
seam.
Cut the box in half
using a metal ruler and a sharp craft knife.
Set the right half of
the box aside for later. Open the left half of the box and lay it
flat.
Cut the two bottom
flaps off at the fold and set them aside for later. Cut the top,
right hand flap off 1/2" above the fold.
Tape one of the cut off flaps to the upper
left hand flap. 1 inch wide clear packing tape works best for
this and is nearly invisible. Make sure the edges of the flaps
line up and the tape is
centered, run the tape the full width of the flap and make sure the
seam is flat.
Cut out Side pattern. Line it up carefully on the folds of
the lower right side panel and mark around the edge with a ball point
pen.
Mark the Launch Rod
Hole only
on the lower right side panel. Repeat marking the other side
panels. Be sure to rotate the pattern 90 degree
clockwise for the next panel. Go in the order of lower
right, lower left, upper left. Make allowance for the slight
narrowness (about 1/8 inch) of the upper left side panel. Extend
the lines from the lower right side panel onto the 1/2 inch flap.
Cut on along the outside
lines with a ruler and a
sharp craft knife.
Run a fillet of glue on the inside of the tape seam on the upper left
panel.
Lay the panel flat and let the glue dry. Do not
tape the inside of the seam.
Spread glue thinly and evenly on the 1/2 inch flap and form the panels
into a partial box shape.
Make sure the 1/2 inch flap is flat against the inside. Let the
glue dry throughly.
This completes construction
of the Top.
