stab surfaces while these are
attached to the fuselage.
Similar to the rudder, mill a
12 mm hole into the root ribs
of the stab fillet. See
dimensions on the photos on
the right. Dry fit stab with
elevators to the fuselage. Use
the elevator torsion linkage
(assembled according to the
drawing/photo) to align the
elevators properly. Then glue
the hinge posts into the stab
spar. Disassemble stabs and
elevators and fill the joints
with 30 min epoxy, where
necessary. Make sure that
these hinge posts are glued
well into the stab.
Now slide the ball bearings
with their plywood sockets on
the torsion linkage and glue
the plywood sockets into the
fuselage. Use 30 min epoxy
and sand the surfaces well
before applying glue. Mount
stab/elevator assembly while
you glue the bearing sockets
in, and make sure the
elevators move freely. After
the glue has set, drill 2 holes
through the LEFT elevator/
torsion linkage with 2.4 mm
diameter. Tap an M3 thread
into each hole, counter sink
the screw head into the
elevator from the bottom side
and mount both bolts. NOW
drill the holes for the opposite
RIGHT elevator, first
adjusting both trailing edges
exactly to the fillets on the
fuselage (you can trust the
incidence of this fillet 100%).
Next tap these holes M3,
countersink the bolt heads
and install the bolts to see the
result of your work. In case

38mm
Center of torsion linkage is 38 mm behind rear edge of stab tube
Use 0.8mm plywood as spacers between the edges of the counter
balance surface of the elevator,to make sure nothing locks up.
Make sure the root surface is matching the fillet with symmetri-
cal gaps on both sides.
Make sure that
the torsion
linkage stays in
during the whole
joining process.

Insert 30 min epoxy through
the root ribs to fill the joints of
the hinge posts to the rear stab
spar. Then place it vertically
until the resin has cured. That
way it will not run off the joint.
