48.
Sand off the ink lines and smooth both
sides of the fin.
49.
Mark a center line on top of the fuselage
where the fin will go.
50.
Cut out the slot in the top of the fuselage
where the fin tab will go. This cut out
should be 2-1/2" long.
51.
Trial fit the fin into the fuselage but don't glue it in place until later.
52.
Pin the stabilizer in place.
53.
a. Turn the fuselage over and measure to be sure the stabilizer is level. All
measurements from the leading edge and trailing edge should be the
same. If they aren't, trim the fuselage until the stabilizer is level.
b. Cut slots in the stabilizer and elevator (1/8"x1"x12" balsa) for the hinges as
indicated on the plans. Do not glue these in until after covering.
NOTE: Some builders prefer to finish the tail pieces separately then glue on to the finished airplane. If you wish to do so do
not glue the tail on until after covering. Be sure to leave bare wood exposed where the parts will be glued for a good bond.
54.
Install the horns.
55.
Cut or file off the ends of the horn
screws.
56.
Glue the stabilizer in place. Be sure it is
level.
57.
