5.
Carefully apply masking tape around
the top and bottom edge of the root rib of each
wing half to protect them from damage caused
by epoxy.
6. Mix a generous amount of 30 minute
epoxy. Coat the exposed half of the dihedral
brace, and the remaining wing joiner box and
both root ribs with epoxy. Slide the two wing
halves together and carefully align them at the
leading and trailing edges. Wipe away any
excess epoxy using paper towels. Use mask-
ing tape wrapped around the centre section to
hold the halves in place until the epoxy cures.
2. Remove the aileron servo. Place the
mount onto the wing, aligning the cutout in the
mount with the cutout 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 mod-
eling knife, carefully remove the covering from
inside the outline you drew.
5. Using 6 Minute Epoxy, glue the servo
mount into place. Remove any excess epoxy
using a paper towel and rubbing alcohol. Use
pieces of masking tape to hold the tray in place
until the epoxy fully cures.
INSTALLING THE AILERON SERVO MOUNT.
8.
Peel off the backing from the self
adhesive covering strip. Apply the strip to the
centre section of the wing starting from the
bottom trailing edge. Wrap the strip all the way
around the wing until it meets the trailing edge
again. Trim off any excess strip.
7.
When the epoxy has cured, carefully
remove the masking tape from the wing.
1. Install the rubber grommets and brass
collets onto the aileron servo. Test fit the servo
into the aileron servo mount.
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.
