3. * You will need a double sided heavy duty servo
output arm.
4. Measure 1/2” from the bottom of the rudder
and 3/8” back from the hinge line and drill a
9/64” hole for the rudder control horn. Install
the 6-32 x 2-1/2” threaded rod with a nut and
washer on each side. Center the rod in the
rudder. Install the nylon control horn fittings on
each end.
7. Install the pushrods in the servo output arm
and retain using the nylon swing in keepers.
5. Locate the two 2-56 x 9” pushrods and install
the nylon snap links on the ends as we did
with the ailerons. Install the silicone keepers
and attach to the pushrod fittings on the rud-
der.
6. Center the rudder servo and tape the rudder
in the neutral position. Mark the position of the
pushrods where they cross the control arm
and make a 90 degree bend. Cut the bend off
at 3/8”.
