joint. Another possibility is to use electrical tape, We have even seen successful
installations that use a loop of dental floss to tie the connection together! How
ever you do it, make sure the connection is retained.
Now is a good time to double check the operation of the servos and harnesses
BEFORE you run the wiring through the wing! Use the Y-Harness for the aileron
servos and the reversing Y-Harness for the flap
servos so you can confirm the operation of the
complete harness before you install the wiring.
RECOMMENDED: for the aileron servos, remove
the output arms and displace them by rotating the
arms one or two splines FORWARD of the centered
position. This will provide differential throws
(ailerons will move UP farther than DOWN) and
somewhat reduce the need for rudder input when turning & banking.
The Reversing Y harness is the simplest means to get both flap servos moving the
same direction. Plug both flap servos into the Reversing Y, then - if needed -
remove the servo arm from one servo and reinstall it so it matches the position of
the other servo.

5. As shipped, the servo bays are covered over with
Oracover. Use a sharp modeling knife to open up
these bays, then use a trim iron to seal the edges of
the Oracover to the servo bays.

6. Next up is to route the servo wiring through the wing and get the servos in position
so we can install the control linkages. Find the pull through string in aileron servo
bay: it is wrapped and glued to a balsa stick. The
other end is tacked inside the access hole in the
wing root. Remember that the correct servo pair
for each wing are the ones that when installed
orient the bottoms of the servos toward the wing tip
and the pushrod fairings both toward the wing root.
Securely tape the aileron servo extension plug to
