24. Remove the cover and use a drill and 1/8-inch (3mm) drill bit to drill
the two holes for the upper gear door mounting screws. The door
can now be attached to the mounts using the four M3 x 12 button
head screws and 2mm hex wrench.
25. If the gear door is not fl ush with the bottom of the wing, the mounts
may need to be adjusted. The mounting area for the lower mount
can also be sanded using medium grit sandpaper to make any
adjustments to the gear door alignment.
26. Use a hobby knife or other sharp tool to puncture the covering at the
screw holes that will secure the cover to the wing. Also remove the
covering to clear the retract mechanism.
27. Place the cover into position. Use a felt-tipped pen to mark the
locations for the mounting screws
28. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill the mounts for
the retract covers.

29. Thread an M2 x 10 sheet metal screw into each hole using a #1
Phillips screwdriver. Remove the screws before proceeding.
30. Apply a small amount of thin CA to harden the threads made in the
previous step. Allow the CA to fully cure before installing the retract
cover.
31. Secure the retract cover to the wing using four M2 x 10 sheet metal
screws. Use a #1 Phillips screwdriver to tighten the screws.
32. Check that the retract can be fully extended without the gear door
hitting the cover. Trim the gear door as necessary if it hits the cover.
 There will be movement in the gear during their operation so
make sure there is a gap between the gear door and wing so
they do not contact each other during the operation of the gear.
33. Use hobby scissors and medium grit sandpaper to prepare the hub
caps for installation.
 The hub caps can be painted if desired. Be sure to fully scuff and
prepare the surface. Applying paint directly to the hub cap with
no preparation will result in flaking paint. Always test paint on a
piece of scrap material to check its compatibility to the plastic.
