apply a coating of epoxy to the inside of the stab pockets in
the fuse. Wipe away any excess epoxy that gathered on the
outside of the fuse. Apply a coating of epoxy to the exposed
wood on the stab halves. Insert the stab halves into the
fuse and clean up any epoxy that squeezes out with alcohol.
Carefully fi t the alignment fi xture onto the stab halves. If you
have to make adjustments to bring the fi xture parallel with the
wing, do so now. Double check everything and make sure all
the excess epoxy is cleaned off the stabs and fuse. When
satisfi ed, let the epoxy
fully cure undisturbed.

4. Prepare your elevator servo by electronically centering
it and choosing the best orientation of the servo arm on the
output spline. Cut off the unused arms. Enlarge the outer hole
of the remaining servo arm that is approximately 9/32" [7.1mm]
from the servo arm center using a #60 drill bit.
❏
5. Install the elevator servo into the servo tray as shown.
The servo can be glued down. However, we chose to mount
it with screws included in the servo hardware bag in case it
needs to be repaired or replaced in the future. If you choose
to install the servo using screws, pre-drill the mounting holes
using a 1/16" [1.6mm] drill bit. Thread a mounting screw into
each hole and back it out. Apply a drop of thin CA to each
hole to harden the wood. When the CA is dry, install the servo.
❏
6. Cut the backplates from two control horns and enlarge the
outer holes in the control horns with a #60 bit. Fit the control
horns onto the Z-bends of two 25-1/4" [641mm] pushrods.
Insert the pushrods into the elevator outer pushrod tubes. As
you did with the ailerons, align the holes of the control horns
over the hinge line and press the mounting posts against the
elevators leaving indentations. Drill 3/32" [2.4mm] holes at
the indentations.
❏
7. Glue the control horns and backplates to the elevators
using medium or thick CA glue.
❏
8. Glue the plywood pushrod support pieces together as
shown. The support that has the larger hole in it should be
used for the elevator pushrods.
