BUILDING THE TAIL SECTION
PREPARE THE FIN AND RUDDER
Sandthe forward and rear sectionsof the fin if neces-
sary for a good fit. Working over the plans, glue the fin section
pieces together. Sand both sides of the rudder.
CUT THE HINGE SLOTS IN THE FIN AND RUD-
DER; CUT OUT RUDDER FOR JOINER CLEAR-
ANCE
Draw centerlines down the trailing edge of the fin
and the leading edge of the rudder. Mark and cut the hinge
slots. Two hinges are used above the stabilizer. The third hinge
should be just below the stab and above the tail wheel strut
tab. Cut out part of the rudder leading edge for elevator joiner
wire clearance. Wait to shape the leading edge until the hole
is drilled for the tail wheel tiller arm later.
3. GLUE STAB PARTSTOGETHER; SANDTHE STAB
AND ELEVATORS
Check the fit and sand the forward and rer parts of
the stab so they fit together well. Glue them together. Sand both
sides of the stab and elevator halves.
4. DRILL HOLES IN THE ELEVATOR HALVES FOR
ELEVATOR JOINER WIRE
Draw a front to back centerline down the top side of
the stab and a centerlinedown the leadingedges of the elevator
halves. Mark the center of the elevator joiner wire. Align the
stab, elevator and joiner wire and mark the hole locations for
the joiner wire arms on the centerline of the elevator leading
edge. Drill the holes.
