Take a brass clamp and #2 x 5/16” sheet
metal screw to attach the larger diameter
nylon tube to the fuselage next to the rudder
pushrod exit hole.
2.
Thread a 3-1/4”” double threaded rod into one
end of the smaller nylon tube.
Insert the smaller nylon tube inside the larger
tube on the side of the plane.
Thread a nylon clevis on to the end of the
push rod and connect the clevis to the planes
rudder control horn.
Note: You might have to bend the wire to allow the
pushrod to move back and forth inside the
tubing.
