SERVO INSTALLATION.
5) Using Kwik Bond 5 Minute Epoxy, glue
the servo mount into place. Remove any ex-
cess epoxy using a paper towel and rubbing
alcohol. Use pieces of masking tape to hold
the tray in place until the epoxy fully cures.
2) Place the mount onto the wing haft,
aligning the cutout in the mount with the cut-
out in the wing. The two notches in the mount
should face the leading edge of the wing.
 3) While holding the servo mount firmly in
place, trace around it using a pen.
4) Remove the mount, and using a model-
ing knife, carefully remove the covering from
inside the outline you drew.

1) Install the rubber grommets and brass
eyelets onto the aileron servo.
Because the size of servos differ, you
may need to adjust the size of the precut
opening in the mount. The notch in the sides
of the mount allow the servo lead to pass
through.
