2) Place one wheel collar into the molded re-
cess in the nylon steering arm. Make sure the threaded
hole in the wheel collar is aligned with the predrilled
hole in the side of the steering arm.
q
3) Slide the nose gear wire up through the lower
nylon mounting bracket, through the steering arm, and
up through the upper mounting bracket.
The steering arm should face the left side of
the fuselage (looking from the front) and the
coil in the nose gear wire should face the back of the
fuselage.
q
4) Using a ruler, measure from the bottom of
the firewall and adjust the height of the nose gear until
the top of the coil is 3/16” down from the bottom of
the firewall.
q
5) Holding the nose gear wire at the proper
height, rotate the wire so that the axle is straight.
Carefully rotate the steering arm so the tip of the arm
is about 3/4” in front of the firewall.
q
6) While holding everything properly aligned,
tighten the set screw in the steering arm to lock the
nose gear in position. See photo # 13 below.

7) Using a pen, place a mark on the firewall,
behind the outermost predrilled hole in the steering
arm. The mark should be even with the arm.
q
8) Rotate the steering arm out of the way. Using
7/64” drill bit, drill a hole through the firewall at the
mark made.
q
9) Using a ruler and a pen, measure and place a
mark on the forward bulkhead 7/8” down from the
top of the wing saddle and 3/8” out from the inside
edge of the fuselage side. See figure # 9 at top right.

10) Using a 7/64 drill bit, carefully drill a hole
through the forward bulkhead at the mark made.
q
11) Using a ruler and pen, measure and place a
mark on the forward servo tray support bulkhead,
3/8” down from the top of the wing saddle and 1/4”
out from the inside edge of the fuselage side. See
figure # 10 below.

12) Using a 7/64 drill bit, carefully drill a hole
through the forward servo tray support bulkhead at
the mark made.
q
13) Slide the 3mm x 250mm pushrod housing
through the hole in the firewall, through the hole in
the forward bulkhead, and through the hole in the for-
ward servo tray support bulkhead. The end of the
tube should be flush with the firewall.
q
14) Apply a couple of drops of Kwik Bond Thin
C/A to the pushrod housing where it exits the fire-
wall, where it passes through the forward bulkhead,
and where it passes through the forward servo tray
support bulkhead. This will hold the housing securely
in place.
q
15) After the C/A has cured, use a modeling
knife and cut off the nylon pushrod housing about
1/8” beyond the back edge of the support bulkhead.
q
16) Notice one end of the 1.5mm x 250mm push-
rod wire has a Z-Bend premade in it and the other
end is plain. Slide the plain end of the wire into the
end of the pushrod housing at the firewall. Remove
the nose gear and steering arm assembly from the two
