Elevator Servo Installation
1. Install the elevator control horn on the inboard
edge of the elevator on the right side of the
fuselage. Align so the holes for the clevis are
centered over the hinge line.
2. Install a clevis on the end of the 2-56 x 24”
pushrod as we did with the ailerons and rud-
der. You may need to push the rod through the
nylon tube from the servo compartment to
open the hole in the side of the fuselage.
Insert the pushrod into nylon tube and attach
the clevis to the elevator control horn..
3. Install the elevator servo in the opening pro-
vided in the tray. The opening is made wide so
you can align different length servo arms with
the pushrod. To get full potential out of the
plane you will need a 1” to 1-1/4” heavy duty
servo arm.
4. Center the elevator servo and tape the eleva-
tor in neutral. Mark the location where the
pushrod crosses the servo arm and make a
90 degree bend. Cut the bend at 3/8”. Install
the pushrod and retain using one of the nylon
swing in keepers.
