3. Using the elevator pushrod wire, position the control horn
so that the four pushrod holes are in line with the elevator hinge
line. Mark the location of the mounting holes onto the elevator.
Drill a 3/32" [2.5 mm] hole on the marks, drilling through the
elevator. Attach the control horn to the elevator using two
2-56 × 1/2" [12 mm] mac hine screws and the contr ol horn
back plate. Remove the screws and apply a couple of drops
of thin CA to both holes to harden the wood. Then, reinstall
the control horn.

Switch on the receiver and transmitter and center the elevator
trims. Install a servo arm on the servo so that it is perpendicular
to the centerline of the servo.

hole ¼" (7mm) from the center of the servo arm is inline with
the pushrod wire. The servos can either be glued to the servo
tray with medium CA or attached with 2 × 6 mm self tapping
screws. The screws do not require a pilot hole; just thread
them into the plywood tray.

Slide the wheel collars over the two pushrods, positioning
them so that they are close to the ends of the two pushrods.
