the rubber bands to rotate with less friction.

they are in the same place when the halves are
assembled. Use a small file or carefully use

hanger to verify that the groove is big
enough. Do not glue the hangar in because it
will get in the way while shaping the ship.

Make a groove across the back
of the spaceship with a round file for the rear rubber band holder to fit into. Make
the groove at 90 degrees from where the body joint
is for additional strength. There will be a
lot of stress on this section when the rubber band
Step: Slip the red covering over the
wire from the straight side to the curved side
before assembling anything else on the
propeller. Use the needle nose pliers to
hold the straight side and push the red covering
over the hook. The directions tell you to do
this after the propeller is assembled but it is
much harder to get the covering on from the curved

rubber bands with glycerin. It is very beneficial
to soak the rubber bands in two parts "GREEN
SOAP", one part "GLYCERIN" and one
part water. Rub this mixture onto your
rubber band at least an hour before racing.

found that 3 rubber bands works well. They
give you 4 but that gets too bunched up inside the
ship and they sometimes won't unwind. Attach

Exercise the rubber bands with partial winding
before applying the full winding amount. It
is helpful to warm up your rubber band by
winding it in 50 turn increments and releasing
after each winding until you have wound up to
about 150 turns. Our pack used about 120 turns for
a race. We think that more than 150
turns is too much and puts undue stress on the
rubber band and rocket.
