Find the piece of yellow Kevlar® Cord (string). Securely
tie this to the top of the Engine Mount as shown in
Figure 7.
(Thing-a-ma-FACT: Kevlar® Cord
is a very strong thread that is
used here to provide a strong connection between the bottom of
the rocket and the nose cone. Kevlar® thread is
SO
strong that it
is also used to make bullet proof vests!)

Figure 8
shows you many important details about the
3 fins that are provided with your model rocket kit. These
fins were cut with a computer controlled laser beam for an
exact fit! Carefully remove the 3 fins from the sheet of
balsawood and place a small mark at the leading edge of
each fin.
(
Thing-a-ma-FACT:
Fins
are used to control the
model’s flight by keeping it pointed straight during flight.)
