Triskelion Instruction Sheet: FK-INS-SP010 Rev: B
6.
Your
Triskelion
model rocket kit comes with
Laser-Cut
Fins
to make assembly easier. In some kits these are
loose, in others they are attached to a sheet of balsawood.
If your fins are attached, carefully removed them and
discard the scrap balsawood.
Figure 6
shows you what
your fins look like and what they are called. It also
identifies the parts of a fin and other important information
about them. Also note that all of the fin edges are flat.
This is fine as this model is designed to be built and flown
with flat edges on the fins. However, you are free and
encouraged to try different things and the bottom of Figure
6 gives you a few ideas of how you can shape the leading
edges of your fins.
NOTE:
Only modify the leading edge.
Figure 6
7.
Referring to
Figure 7 & 8,
apply a thin bead of glue to the
tip of one
Fin
and attach one
Fin Tip
as shown.
NOTE:
Each Fin Tip has a lightly etched line to show you where
the Fin should be attached. These fins are designed so
that when properly glued the assembly will stand on its
own while it dries. Repeat this step for the remaining two
Fins and Fin Tips and set aside to dry.
Figure 7
8.
Figure 8
shows an end view of the fin assemblies from
Step 7.
Study this figure as it shows you the proper look
your fin assemblies should have. The image on the left
shows the fin straight up and down and centered on the
Fin Tip. This is correct. The other two images show
incorrect assemblies. The center image shows the fin off-
centered and the right most image shows the fin at an
angle.
Straight fins mean straight flights for your model
rocket!

(
NOTE:
Read steps 9 & 10 before installing your engine
mount.) Referring to
Figure 9 & 10
, apply a liberal bead
of glue about 1 ½” inside one end of the Body Tube (the
largest tube in your kit). This bead of glue should go all
the way around the inside of the tube. Insert your Engine
Mount as shown, until the lower ring is just inside the Body
Tube. (
NOTE:
Make sure you install this such that the
Engine Hook is pointed down as shown in the figure)
Figure 9
10. To complete the installation of your Engine mount, grasp
your Body Tube as press down on a firm flat surface (like
a desktop) until the Engine Mount is pushed into the Body
Tube all the way, as shown in
Figure 10.
This will assure
that the Engine Mount is properly installed and is flush
with the bottom of the Body Tube. Let dry before going on
to Step 11.
Figure 10
11.
NOTE:
You must be sure that there is no wet glue on the
inside end of the Body Tube before performing this step.
Slide the Body Tube (Engine Mount down) onto the Fin
Alignment Template, right over the ring that you glued
down in Step 1, as shown in
Figure 11.
This will hold your
model upright and steady as you glue your fins on.
NOTE:
If you are concerned about wet glue, you can
cover the ring and Fin Alignment Template with one
smooth sheet of clear plastic wrap to prevent accidental
gluing.
