 5. Once aligned, use a felt-tipped pen to trace the outline
of the fuselage onto the top and bottom of the stabilizer.
 6. Remove the stabilizer from the fuselage. Use a hobby
knife with a new #11 blade to trim the covering slightly
INSIDE the lines drawn on the stabilizer. Use light
pressure so you do not cut into the underlying wood.
Remove the covering from the inside of the cut lines on
the top and bottom of the stabilizer.
Important: Cutting into the underlying wood will weaken
the stabilizer and it could fail in flight.
Hint: Use a soldering iron or hot knife to cut the
covering, as they will melt it and require less pressure,
reducing the chances of cutting into the underlying wood.
