Step 5
Slide the nose gear assembly into the nose gear blocks and
steering arm. Note the direction of the coil spring and that it
faces to the back of the fuselage.
Step 6
Apply a drop of threadlock on the 3mm x 3mm setscrew.
Use the setscrew to secure the steering arm to the nose gear
assembly. The setscrew must be tightened on the notch of
the nose gear wire or it might vibrate loose during flight or
cause the nose gear to twist if the model encounters a poor
landing. Use a 1.5mm hex wrench or ball driver to tighten
the setscrew.
Step 7
Use a hobby knife to remove the covering to expose the
slot on the bottom of the fuselage for the main landing gear
wires. The main gear slot is located 5

behind the rear edge of the fuselage hatch.
Step 8
Apply a thin coat of medium CA to the slot to seal the
exposed wood. This will keep fuel from soaking into the
wood and causing it to soften over time. Use a paper towel
to wipe away any excess CA. This is not necessary if you are
using an electric power system.
Step 9
Use a hobby knife and #11 blade to bevel the inside edge
of both holes in the main landing gear block. This is
necessary to accept the radius of the bend on the main gear
assemblies, allowing them to fit snug in the slot.
