Section 10: Rudder Control Horn Installation
Step 2
Use a 5/32" drill bit to drill through the rudder. A
drill press will ensure the hole is perpendicular to
the rudder.
Step 3
Tap the hole drilled in the previous step using
an 8-32 tap.
Step 4
Cut a length of 8-32 threaded rod to 5". Thread the
rod into the rudder until it is centered in the rudder.
Step 5
Thread the control horn standoff nuts onto the
threaded rods. Use a drop of threadlocking compound
to prevent the nuts from coming loose in flight.
Step 6
Bend the threaded rod forward 10 degrees. This
is done to align the control horns with the rudder
hinge line.
