Step 4
Remove the covering 1/16" below the line drawn
in the last step.
Step 5
Mix 1/2 ounce of 30-minute epoxy. Apply the epoxy
to the tab on the fin and to the area on the top of
the fuselage where the covering was removed.
Position the fin in the slot and check the alignment.
Use masking tape to hold the fin in position until the
epoxy fully cures.
Hint: Use rubbing alcohol and a paper towel
to clean up any excess epoxy.
