6. Locate the 6-32 x 2" [51mm] threaded rod. Draw a
line on the rudder that is 5/16" [8mm] away from the rudder
hinge line. Draw a second line that is 5/16" [8mm] from the
bottom of the rudder. Using a 5/32" [4mm] drill bit, drill a hole
through the rudder at point where the two marks intersect.
Slide the 6-32 x 2" [51mm] rod through the hole, apply a drop
of thread locker to each side of the rod and secure it with the
two 6-32 nuts and washers.
❏
7. Install a nylon swivel onto one side of the threaded
rod. Locate the rudder pushrod. Install the nylon clevis onto
the threaded end of the pushrod. Slide the silicone clevis
keeper over the pushrod. Using coarse sandpaper, roughen
the outside of the pushrod from the threads to 4 inches from
the threads. Clean the pushrod using alcohol.
❏
8. Lightly coat the outside of the rough portion of the
pushrod with JB Weld (JBWR8276) or 6 minute epoxy. Slide
the 3-3/4" [95mm] long carbon tube over the pushrod leaving
approximately 1/8" [3mm] from the threads to the carbon
tube. Install the pushrod onto the nylon swivel.
❏
9. Center the servo and the rudder. Mark the location
where the rudder pushrod intersects the servo arm. Make a
90° bend in the pushrod at the mark. Enlarge the servo horn
hole using a 5/64" [2mm] drill bit. Place the bend through the
servo hole, slide the FasLink in place, and trim off the excess
pushrod. If the rudder is no longer straight when the rudder
servo is centered, adjust by rotating the clevis as required.
Once the rudder is straight, snap the clevis shut, and slide
the silicone clevis retainer over the clevis.
