on the remaining wing panel.

2) Inside the aileron servo bay you will see the plywood servo
mount. You will also see a small rectangle of plywood with thin line
tied to it. This line leads through the wing and exits at the root rib,
where you will see the line attached to another plywood piece
taped to the rib. This line will be used to pull the aileron servo lead
through the inside of the wing, exiting at the root rib.
Before installing the aileron servos you must determine if the servo
cable lead is long enough to go through the wing, exit the root rib
and have enough length left to enter the fuselage and connect to
the receiver. This length is typically 13-1/2" and it's unlikely the
servo lead will be long enough. If not, you must add a servo
extension lead to make up the needed length.
A 6" servo
extension lead will usually be more than enough.
Plug the
extension into the end of your servo and secure well with tape to
prevent accidental disconnection. Use the hardware supplied with
your radio system to install the grommets and eyelets onto the
servo. It is now ready to install into wing.
❑
3) Pull the plywood rectangle and line out of the servo bay
opening. Remove the plywood from the line and discard it. Tie the
line securely to the connector end of the servo lead. Remove the
tape from the plywood rectangle at the root rib. Carefully pull the
line and the servo cable lead through the wing until the servo cable
emerges from the root rib.
❑
4) Fit the servo onto the two servo rails in the wing panel (note
that the servo is mounted with its output arm toward the leading
edge of the wing), taking up any slack in the servo cable, by pulling
the cable a little from the root rib end of the line. Use a pin-vise
and a small dia. bit to drill four small guide holes through the servo
rails for the servo mounting screws. Use the screws supplied with
your radio system to mount the servo securely in place to the
servo rails. Repeat this procedure with the remaining wing panel.

5) The ailerons are now hinged to the wing panels.
The
supplied hinges are the CA type. The installation procedure for
these hinges is the same for all of the flying surfaces on this
airplane.
The hinges have a die-cut center slot in them that can be used to
accurately place and center the hinge equally into both the wing
panel and the aileron. To do this, use a business card and a pair
of scissors to cut eight or so "wedges". These should be wide
enough at the top so as to not pass through the hinge slot cut-out.
Press the hinges in place into the wing panel up to the hinge slot
cut-out. Place a card wedge into each hinge slot cut-out and then
press the aileron in place onto each exposed hinge half, up to the
card wedges. Align the outer tip of the aileron with the wing panel
tip. The hinges are now in proper position for permanently gluing
in place with thin CA glue.
Flex the aileron downward, exposing both sides of the hinges
between the wing and aileron (using a piece of masking tape to
hold the aileron in this position will free up both of your hands). For
CA hinges, we always suggest using a fine-tipped applicator on
the glue bottle to better control the flow. Remove the wedge from
one of the hinges and apply four drops of CA glue to each hinge
edge. Remove the wedge from the next hinge and again apply
four drops of glue to each hinge edge. Repeat this process for the
remaining hinges. Remove the tape holding the flexed aileron to
the wing panel and flex the aileron in the opposite direction, again
