6. Fit the tail wheel hatch cover in place and
secure it with four #2 x 3/8" [9.5mm] screws. Be sure
to harden the screw holes with thin CA.
❏
7. Install the tail wheel onto the tail wheel axle
using two 1/8" [3.2mm] wheel collars and two 4-40
set screws. Apply a drop of threadlocking compound
to the set screws. Be sure that the wheel rotates on
the axle freely. Oil the axle if necessary.

8. Install the rudder to the fuselage using CA
hinges. Temporarily install a metal threaded clevis
onto a 36" [914mm] pushrod 15 complete turns.
Insert the pushrod into left pushrod exit slot in the
fuselage. Connect the clevis to a nylon control horn
and position the horn on the left side of the rudder
over the plywood plate, being sure that the holes in
the control horn are properly aligned over the rudder
hinge line. Mark the locations of the control horn
mounting holes. Drill 1/16" [1.6mm] holes at your
marks, being sure not to drill through the rudder.
Attach the rudder control horn to the rudder using
two #2 x 3/8" [9.5mm] self-tapping screws. Remove
the screws and harden the holes with thin CA.

9. Center the rudder in the neutral position and
mark the pushrod where it crosses the second to
outer hole in the rudder servo arm. Remove the
pushrod from the fuselage, bend the pushrod 90
degrees at the mark you made, and cut off the excess
pushrod 1/4" [6mm] beyond your mark. Remove the
clevis from the pushrod and insert the pushrod into
the rudder pushrod tube from the forward end. Hook
the 90° bend into the second to outer hole in the
servo arm and secure it with a nylon FasLink. Thread
a 2-56 nut, metal clevis, and silicone clevis retainer
onto the aft end of the pushrod. Make any necessary
adjustments to the clevis position and connect it to the
rudder control horn when satisfi ed. Tighten the 2-56
nut against the back of the clevis with threadlocking
compound. Be sure to slide the silicone clevis retainer
to the end of the clevis.

1. The fuel tank can be assembled as a two line
system consisting of a vent (pressure) line to the
muffl er and a carb line. Filling and emptying of the
tank would need to be done through the carb line, or
an optional fuel fi ll valve (not included). The tank can
also be assembled as a three line system having a
