9. Using the pushrod wire as a guide, locate the plywood
plate in the elevator servo. Position the large nylon black control
horn on the plate, in line with the pushrod wire. Position the
control horn on the hinge line the same way you did for the
ailerons. Drill a 3/32" [2.4mm] hole through each of the holes
in the control horn. Drill only through the plywood plate. Do
not
drill through the top of the control surface . Mount the
horn with four #4 x 1/2" [13mm] screws.

10. Install the servo pushrod as shown. Make any
adjustments required to the arm to get the proper length for
the pushrod so when the servo is centered, the elevator is
aligned with the stabilizer.
❏
11. Repeat steps 2-10 for the right side stabilizer / elevator.
❏
12. Locate the two carbon fi ber stab tubes. Slide the shorter
length tube into the forward most hole in the rear of the fuselage
and the longest tube in the rear hole in the fuse. Through the
opening in the back of the fuselage, install the servo leads
into the fuselage up to the radio compartment and then test
fi t the stabs to the fuselage.
❏
13. When you are satisfi ed with the fi t, glue the stabs
one side at a time to the fuselage with 30-minute epoxy.
Apply the glue to the tubes, the root rib of the stab and the
fuselage side. Clean any excess epoxy with a paper towel
and rubbing alcohol. Use masking tape to hold the stabs
tight to the fuselage while the glue is curing.
