3. Place the 3/32-inch (2.5mm) drill bit in the drill. Set
the drill so it is 1-inch (25mm) from the chuck to prevent
accidentally drilling through the top of the wing.
4. Drill the four mounting holes for the landing gear
base using the drill and drill bit prepared in the previous step.
5. Place 2–3 drops of thin CA in each hole to harden
the surrounding wood. This makes it difficult for the screw
to pull loose on hard landings.
6. Slide the main gear into the landing gear base. The
top of the gear will be flush with the top of the base.
7. Place the gear and base on a flat surface. The wheel
axle will rest flat on the surface when the base is resting flat.
This will position the wheel straight forward when installed.
8. Use a #2 Phillips screwdriver to tighten the screw
in the base on the wire. This will leave a mark on the wire
where you will need to file a flat area for the screw. This will
prevent the gear from rotating during takeoff and landing.
Use a flat file to make the flat on the wire.
9. Once the flat is on the main gear wire, insert it back
into the base and tighten the screw. Check the alignment to
make sure the flat is in the correct location. Once complete,
use threadlock on the screw and tighten it to secure the
landing gear wire.
10. Place the block in the wing. Check that the spring
faces the rear and the wire for the wheel faces the wing
root. If not, you will need to prepare the opposite landing
gear wire for this particular wing panel. Use four #6 x 1-inch
sheet metal screws and a #2 Phillips screwdriver to secure
the landing gear block in the wing.
