marks. Wick two to three drops of thin CA into the holes to
harden the underlying balsa, then re-drill the holes. Attach
the horns using 2-56 x 3/4" socket head cap screws and
nylon nut plates. Do not overtighten the screws, crushing
the underlying balsa. Center the ailerons, then mark the
pushrods at the point where they meet the holes on the
servo arm. Make a 90º bend in the wires at this mark. Cut
off the excess wire 3/8" [9.5mm] above the bend. Insert the
bent wire pushrod into the servo horn, then attach the
linkage to the servo using a nylon FasLink
™
as shown in the
photo. Repeat this step for the other aileron linkage.

1. File a flat spot on the front of the nose gear wire where
it passes through the nose gear bearing. This provides a
better area for the screw to bite and helps keep the steering
arm in place.
❏
2. One 5/32" wheel collar, a nylon steering arm, and a
6-32 x 1/4" socket head cap screw are used to mount the
nose gear. Place the wheel collar into the steering arm,
making sure the hole in the arm aligns with the hole in the
wheel collar for the set screw. Place the steering arm
between the upper and lower sections of the nose gear
block, and slide the nose gear through both sections of the
nose gear block and the steering arm. The coil on the nose gear
is positioned as close to the mount block as possible without
binding. Use the photo and sketch to install the nose gear.
❏
3. Drill a 3/16" [5mm] hole in the firewall for the nose gear
pushrod tube. When drilling the hole, align it with the outside
hole on the steering arm.
❏
4. Now for the trickiest part of the assembly, routing the
nose gear pushrod tube. The tube will enter from the front of
the fuselage through the hole just drilled. Route the tube up
through the servo tray before former 2. It will exit along side
of the fuel tank above the servo tray and next to former 2.
Trim former 2 to provide clearance for the tube and to
properly align it with the servo arm. The photo shows the
pushrod tube as it is properly routed.

5. Assemble the steering pushrod using one nylon clevis,
one clevis retainer, one 2-56 x 1" threaded rod, one 2-56 x
