yourself with the assembly manual before start-

mount all the hardware.
2. Cut out the slots in the rudder to accept the G-

are equal distance on both sides of the rudder to
prevent an off center throw. Apply 15 minute
epoxy to the horns making sure the holes are
filled and then slide the two keeper lock plates
in place at the same time. Wipe off any excess
epoxy with rubbing alcohol. Install the 4/40 ball
and swivel rod ends to keep the horns aligned
while the epoxy cures. Only snug up the bolts
