Place the servo tray on the center of
the main wing set. Use marker to 
mark the location of the servo tray on
the main wing.

Use hobby knife to remove the
covering over the hole.

Use epoxy to secure the servo tray in
position.

Place the servo on the servo tray and
secure it in place with the screws 
come with the servo.

Take two pieces of 330mm rods out
of the hardware bag. Use side cutter
to cut all the parts out of the plastic
parts tree. Screw a clevis onto the
threaded end of each rod. Thread the
aileron horns onto the aileron torque
rods in the wing until the rod is flush
with the aileron horn. Attach the
clevises onto their respective aileron
horns. Center the aileron servo and
using marker to place a mark on the
unthreaded end of the aileron
pushrods where they pass their
respective servo arm.

Using z-bend pliers, make a z-bend 
at the marked location on each rod
and cut off the excess rod.

Use 2mm reamer to enlarge the hole
on the servo arm. Place a piece of
fuel tubing over the clevises.
This will provide extra insurance
against the clevises accidentally
coming open. Install the z-end into
the hole of the servo arm. Adjust the
aileron torque rod length by screwing
in or out until the aileron is exactly in
the neutral position when the servo is
centered and clevis is in the aileron
horn. Adjust both sides.

Find the pre-serving opening on both
sides of the fuselage for assembling
windows. Use hobby knife to remove
the covering over the openings.
Please reserve 6mm covering on the
edges of the openings.

Use iron (140 C) to trim the edges
