2. Thread a nylon clevis onto the elevator pushrod (exits
out of the right side of the fuse) 20 complete turns and slide
a silicone clevis retainer onto the clevis. Connect the clevis
to the outer hole of a control horn and use the position of the
pushrod exiting the fuse to mark the location of control horn
mounting holes.
❏
3. Drill 5/64" [2mm] holes at the marks you made through
the elevator. Install the control horn with a control horn
backplate using two 2x10mm machine screws. Slide the
silicone clevis retainer to the end of the clevis.
❏
4. Install the rudder pushrod and control horn in the
same manner.
❏
5. Use your radio system to center the elevator and rudder
servos. Cut three arms from a four-arm servo arm for each
servo. Choose the servo arm hole of the remaining arms
closest to 11/32" [8.7mm] from the center of the servo to
install a screw-lock pushrod connector with a nylon retainer
into each servo arm. Loosely install a 3x5mm socket head
cap screw into each screw-lock connector. Using the photo
as a guide, install the elevator and rudder servos onto the
servo tray using the hardware that came with the servos
(be sure to harden the screw holes with thin CA). Slide
the pushrods through the screw-lock pushrod connectors,
center the control surfaces, and tighten the screws against
the pushrods. If necessary, the excess pushrod can be cut
off 1/4" [6mm] beyond the pushrod connectors.
