Inserting and Attaching
the Motor Mount
Step 1 –
Using a Q-tip or your little finger
apply glue around the inside end of the body
tube about ½” in at the end of the slotted for
the fins.
Important:
Do the following motor mount
insertion in one move. Do not stop until the
motor mount is in the correct position.
Step 2 –
Insert the motor mount and push
in until the bottom of the motor tube is flush
with or slightly below the bottom of the body
tube. Both rings should be clear of the fin
slots. Clean any residue glue from the slots
and set aside to dry.
Preparing and
Attaching the Fins
Step 1 –
Press or break out the balsa fins
from the laser cut sheet.
Step 2 –
Sand the leading edge and the tip
of each fin round. Leave the root of the fin
where it inserts and attaches to the body tube
square.
Step 3 –
Apply a bead of glue to the root
edge on each fin and insert the root tab of
each fin into the fin slots on the body tube.
The front root edge of the fins should glue
against the motor tube inside and the rear
root edge against the body tube outside.
Step 4 –
Apply a thin bead of glue along the
length of the launch lug and attach to the
body tube where the launch lug line is
marked. Allow to dry for ½ hour or more.
Important:
Keep the fins and the launch
lug aligned while drying. Make sure the fins
are aligned 120 degrees apart. Use the fin
guide on the next page to align the fins while
drying.
