o 8. Cut a small amount of the hook side of the non-adhesive
back, hook and loop material. Apply it to the battery tray using
some CA glue in the locations shown. Apply the loop side of
some self-adhesive hook and loop material to the underside
of the battery. This will keep the battery from sliding when it
is strapped in.
o 9. Cut the provided non-adhesive hook and loop material
in half. Straps can be made from the included non-adhesive
hook and loop material for securing the battery pack to the
tray by overlapping the mating ends of the pieces. The straps
should be wrapped around the tray and battery tightly. When
you balance the model, the exact position of the battery pack
will be determined. When you know where the pack will need
to be to balanced mark its position onto the battery tray.
o 10. Glue the two hatch dowels halfway into the holes in the
front of the battery hatch. Glue two magnets into the battery
hatch with thin CA glue as shown. Do not use too much CA
because it may prevent the magnets from sitting flush inside
the holes. If the magnets do not sit flush with the aft end of
the hatch, use long nose pliers to carefully press them in
place. Let the CA glue harden without accelerator.
o 11. The magnets in the fuselage must be attracted to the
magnets in the battery hatch. Be sure that the magnets
are oriented correctly and glue two magnets into the
fuselage in the locations shown.
