  Step 8
Glue the elevator hinges in place using the same
techniques used to hinge the ailerons.
 Step 9
Repeat Steps 1 through 8 for the remaining aileron
and elevator.
Hint: Combining the left and right wing/
aileron and/or left and right stabilizer/elevator
while waiting for glue to cure will make
this section move along much quicker.
 Step 10
Since all that’s left is the rudder, this is a good time to
glue it as well. Follow Steps 1 through 7 to complete
hinging the control surfaces. Cut the bottom hinge flush
with the forward edge of the fin post.
It is a good idea to be sure that the aileron and elevator
hinge lines be sealed airtight. Sealing the hinge line has
several advantages. A sealed hinge line gives a greater
control response for a given control deflection. It also
offers more precise, consistent control response and
makes trimming easier. Sealing the aileron and elevator
hinge line is highly recommended. Failure to do so may
cause control surface flutter, resulting in a crash.
    Step 11
Cut a piece of Clear UltraCote® for sealing the ailerons
to approximately 1" x 32" (25mm x 810mm). Fold the
UltraCote down the center with the adhesive side to the
outside making a sharp crease at the fold.
    Step 12
Remove the backing from the UltraCote. Place the folded
crease side into the center of the hinge line on the bottom
of the wing. Using a straight edge as shown, hold one
side of the covering in place while ironing down the
opposite side with a sealing iron. We recommend setting
the iron temperature to 320° for this procedure.
Note: White covering was used
for clarity in the photos.
