sure that there is not much space
between the elevator tips and tips of
the horizontal stab.
See Figure 14.
Figure 14
Take some lithium grease or
Petroleum jelly and apply a very
small amount on both sides of the
hinge point on the flat hinges.
Quique used a round toothpick. See
Figure 15. This will help prevent any
glue in the pivot point.
Be very careful not to get any grease
etc. on the flat part of the hinges.
Also remember that you always glue
the hinges in to the fixed surfaces
first, let the glue harden before you
then glue in the control surfaces.
Remember to check for the correct
hinge gaps for rudder, elevators and
ailerons. You must have the correct
gap to insure the maximum control
deflection necessary for the best 3-D
aerobatics. For hinge attachment we
like to use
Hinge Glue
by Pacer.
You may use epoxy if you wish. If
you use epoxy, use an epoxy with a
curing time that will give you enough
time to work the hinges in place
before the epoxy hardens.

Step 5
Sealing the Control Surfaces
After you are done hinging the
ailerons and elevators, make sure
you seal the hinge line by using clear
ultracote or bright yellow ultracote for
best appearance. Unsealed control
surfaces may cause flutter like
aileron flutter, which may cause your
plane to crash, where sealed control
surfaces will give you better and
crisper response in flight.
For each aileron, cut 36 ½”x1” of
bright yellow ultracote and seal the
hinge line from top using a straight
edge and trim iron.
For each half elevator, cut 11
7/8”x1/2” of bright yellow ultracote
and seal the hinge line from top
same way as you did your ailerons.
Following figures show what it would
look like if you use bright yellow
ultracote to seal the hinge line from
top.
