GLIDER ASSEMBLY
36.
Lay the glider body tube (BT-20D) on a
flat surface. Place a sheet of wax paper over it to
prevent the glue from sticking while the fins dry.
Place a bead of glue on the root edge of one of the
glider wings (14) and attach it to the other wing. As
the joint starts to set, drape the assembly over the
body tube and wax paper and support the ends
while it dries.
34.
Assemble chute using instructions
printed on the canopy. Attach the chute to the
screw eye.
35.
Pull the Kevlar® thread out of the top of
the main body tube. Tie the loose end to one end of
the elastic cord. Tie the other end of the elastic cord
to the screw eye. Put a drop of glue on both knots
to keep them from untying.

19.
Insert the top of the engine mount into
the BT-50 and slide it forward until the mark is even
with the end of the BT-50. Do not stop or the mount
will “freeze” in the wrong place.
18.
Mark the engine mount 1/2” from the bot-
tom end. Apply a bead of glue inside one end of the
largest body tube (BT-50)
about 1” from the end.
20.
Cut out the Booster Marking Guide from
the pattern sheet. Wrap it around the body tube
about 1/4” from the end nearest the engine mount.
Align it so Arrow H points to the engine hook. Hold
it in place with a small piece of tape. Place a mark at
each arrow and write the corresponding letter near
each mark for future reference.
17.
When all the rings are in place and the
knot is pulled up against the top ring, apply a fillet
of glue around all the joints, being careful to keep
the outside surfaces of both rings free of glue. Ap-
ply a bead of glue along the engine hook between
the two rings. Allow to dry. Store the Kevlar®
thread inside the engine tube until needed later.
