1-1/2" threaded rod by cutting off a 4" threaded
end rod and soldering a brass threaded coupler
onto the bare end. Screw this assembly into the
other end of the ball link.
❏
5. Thread a nylon swivel clevis onto the
exposed end of the 1-1/2" threaded rod. Thread the
nylon parts onto the threaded rod until the center of
the ball and the center of the
swivel clevis pivot
are exactly 2-1/4" apart (see photo for step 4).
❏
6. Cut off the threaded end of the rudder
torque rod so the end is only 3/4" from the center
of the torque rod.
❏
7. Screw the nylon swivel onto the rudder
torque rod and attach this assembly to the end of
the pushrod (see photo step 4).
❏
8. Flatten one end of the 1/8" OD brass tube and
solder it onto the top of the tailwheel wire
assembly . Drill a 1/16" hole in the flattened portion
of the brass tube at the top of the tailwheel wire.
Securely screw the ball and nut to the tail wheel
wire. Use two
#4 x 1/2" sheet metal screws to
screw the tail wheel wire assembly to the 1/8" die-
cut
tail wheel mount plate (T W) . Refer to the
photo for proper orientation. Put a drop of 5-minute
epoxy on the threads of each #4 screw and the nut
on the ball link to prevent them from vibrating loose.
❏
9. Slide the rudder pushrod assembly into its
outer pushrod guide tube from the back of the fuse.
❏
10. Position the tailwheel assembly and rudder
torque rod as shown on the plan. Check to see if
the tailwheel and rudder rods are both properly
aligned. Make adjustments if required.
❏
11. Glue the tailwheel assembly to the fuse in
the position indicated on the plan. Use the wheel
collar to position the tailwheel wire so the pushrod
is centered in its passageway through the formers.
Use
thread lock on the wheel collar set screw and
tighten it with an allen wrench.
NOTE: Do not glue the rudder torque rod bearing
tube in position until after the fin is attached. The
rudder torque rod may be taped back out of the
way until more work is done in this area.
❏
12. Glue the die-cut 1/8" plywood F-3C to the
die-cut 1/8" plywood F-3B . Be sure that the 5/16"
punched holes in F-3C and F-3B line up with
each other.
❏
13. Plug F-3B into the forward frame of the
fuselage just behind F-3. Notice that F-3C is on the
forward side of F-3B.
❏
14. Slide the die-cut 1/8" plywood wing saddles
(WS) into place along the bottom of the fuse.
