7. Install a 6-32 x 1/4" [6mm] socket head cap screw into
each of the 3/16" [4.8mm] wheel collars. Install the wheel
pant, a 3/16" wheel collar, the wheel and another 3/16"
wheel collar onto the axle. Center the wheel in the wheel
pant, apply thread locker to the set screw and then tighten
the wheel collar set screws.
You will find the following steps easier if you remove
the landing gear from the wing.

8. The landing gear fairing consists of two laser-cut
plywood formers and the fiberglass fairing. Glue the large
former to the wide end of the fairing and the small former to
the narrow end of the fairing with CA.
❏
9. Slide the fairing onto the landing gear wire, positioning
the bottom of the fairing slightly below the top of the wheel
pant. Mark the location of the fairing on the wire, then
remove the fairing. Roughen the wire in the area of the
fairing with 80-grit sandpaper. Re-install the fairing onto the
wire, making sure it is properly positioned to the wheel pant
and that the front of the fairing is aligned with the front of the
pant. Apply CA to the formers to tack them to the wire.
❏
10. Mix a small amount of 6-minute epoxy with microballoon
filler. Liberally apply the mixture to the former and the
landing gear wire. Do this for both the formers. Allow the
glue to harden.
❏
11. Apply a small amount of medium CA to the trailing
edge of the fairing. Squeeze the trailing edge of the fairing
together, holding it until the glue hardens. Once the glue has
hardened apply a mixture of epoxy and microballoons to the
inside of the trailing edge to give a more secure joint.
