ATTACH THE STICKERS.   It will be
much easier to put the stickers on now,
than later.  See the picture for their proper
location.  (Run the rudder stickers parallel
to the ribs in the fin.  The bottom of the
fin is not parallel to the direction of
travel.)

 

MOUNT THE STABILIZER.  Bolt the
wing onto the fuselage and set the
airplane in a position so that you can sight
over the horizontal stab and wing
together.  Put the stab on its saddle and
make sure that it is level
with the wing. If not, sand
one side of the saddle until
it is.  Measure from the
wing back to the elevator
hinge line on each side and
adjust the stab until the
measurements are the same.

 

Draw a line along the joint
of the stab and fuselage,
both sides, top and bottom.
Remove the stab and remove the covering 3/32”
inside the lines. Add epoxy, reinstall the stab, recheck
the measurements and pin and tape it into position.
Check several times to make sure the alignments are
correct before the epoxy sets.

 

MOUNT THE VERTICAL FIN.  Trial fit the fin in
position.  The tab on the bottom of the fin should fit
all the way down in its slot and the fin should be 90
degrees to the horizontal stab.  You can make
adjustments by sanding the sides of the fin tab a little,
if required.  Draw a pencil line around the fin where it
touches the top of the fuselage.  Cut away the
covering 3/32” inside the line, and also on the bottom
of the fin and the top of the fuselage. When you are
satisfied with the fit, epoxy the vertical fin in place and tape and pin it until the epoxy sets.

 

INSTALL THE ELEVATORS AND RUDDER.  Attach the elevators and rudder using the same
techniques as you used for the ailerons.

 

ATTACH THE TAILWHEEL SUPPORT BRACKET TO THE FUSELAGE.  Hold the bracket
over the rear end of the fuselage and drill 3/32” holes through the front and rear mounting holes.
