2. Install the other control horn to the right side of the
rudder as shown. Apply a bead of thin foam-safe CA around
the base of the control horn.
Install the Pushrods
❏ ❏
1. Using a 1 x 560mm carbon pushrod, one metal
Z-bend, and one piece of 25mm heat shrink tubing,
build one end of the rudder pushrod. Slide three pushrod
supports onto the pushrod. Do not assemble the other end
of the pushrod yet.
❏ ❏
2. Remove the servo arm that you temporarily fi tted
to your rudder servo. Use a #57 [1mm] drill bit to enlarge
the outermost servo arm hole. Fit the rudder pushrod to
the outermost hole. Note: If you don’t have a #57 drill bit,
carefully use your hobby knife to enlarge the hole.
❏ ❏
3. Install one control alignment tool onto the vertical
stabilizer to hold the rudder straight.
❏ ❏
4. Fit the servo arm onto the rudder servo and extend
the pushrod all the way back to the rudder control horn. Fit a
Z-bend to the rudder control horn. Attach the Z-bend to the
rudder pushrod using a 25mm piece of heat shrink tubing.
Shrink the tubing with a hot soldering iron. Note: DO NOT
attempt to use a torch, cigarette lighter or heat gun near
the foam! It is nearly impossible to use these without melting
the foam.
❏ ❏
5. With the pushrod straight, cut 2mm wide slots in the
fuselage for the pushrod supports using a hobby knife. Cut
the fi rst slot so that it is 5-1/2" [140mm] from the Z-bend.
Space the next slot 5-1/2" [140mm] from that and so on.
Ensure that the pushrod is completely straight and use foam-
safe CA to glue the supports into the fuselage.
❏
6. Repeat steps 1 through 5 for the elevator. Use the
1 x 490mm carbon rod and space the pushrod supports
4-7/8" [123mm] apart.
