cure for about ten minutes. Once cured, the aileron
may be stiff and difficult to move. This is normal.
Gently move the aileron up and down about five to
ten times to free it up.
6) Repeat steps # 1 - # 5 for the second aileron.

INSTALL THE TAIL WHEEL WIRE

7) Using a ruler and a pen, measure up 1-1/4"
from the bottom of the rudder, at the leading edge,
and place a mark.
8) Using a 5/64" drill bit, drill a hole into the
rudder at the mark made. Using a modeling knife,
cut a groove from the hole, down to the bottom of the
rudder. Make the groove deep enough for the tail
wheel wire to set flush in. See figure # 5 below.

9) Mix up a small amount of Kwik Bond 5
Minute Epoxy. Apply the epoxy to only those parts
of the tail wheel wire that will be glued to the rudder.
Pack epoxy into the hole you drilled in the leading
edge of the rudder also.
10) Insert the tail wheel wire into the rudder.
Clean up any excess epoxy using a paper towel and
rubbing alcohol. See photo # 15 below.

HINGING THE RUDDER

11) The C/A hinges have already been glued into
the rudder. Slide the rudder and it's hinges into their
precut hinge slots in the trailing edge of the vertical
stabilizer. Slide the rudder in until it is tight against
the trailing edge of the stabilizer. The maximum hinge
gap should be no more than 1/32".

12) With the rudder tight against the stabilizer,
rotate the rudder to one side about 45º. Apply six
drops of Kwik Bond Thin C/A to the exposed area
of each hinge. Allow the glue to cure for about ten
minutes. Once cured, the rudder may be stiff and
difficult to move. This is normal. Gently move the
rudder back and forth about five to ten times to free
it up.

MOUNTING THE TAIL WHEEL BRACKET

13) Align the tail wheel mounting bracket with
the centerline of the fuselage. Use a pen and mark
the two forward mounting locations on the fuselage.
14) Move the mounting bracket to the side. Us-
ing a 1/16" drill bit, drill two pilot holes through the
bottom of the fuselage at the marks you just made.
15) Secure the mounting bracket in place us-
ing two 3mm x 12mm wood screws. See photo #
16 below.

INSTALLING THE TAIL WHEEL

16) Install the 25mm diameter tail wheel onto
the tail wheel wire. Secure the tail wheel in place
using one 2mm wheel collar and one 3mm x 6mm
machine screw. Slide the wheel collar on enough so
it is up against the wheel, but not so tight that the
wheel won't turn. The tail wheel should rotate with-
out binding.
