8. Prepare the cable ends in the tail wheel opening by
passing the cable through a copper crimp, then through the
hole in the 4-40 threaded eyelet. The cable then goes back
through the crimp. Use crimping pliers to compress the crimp,
securing the wire. Prepare one end of both wires at this time.
9. Thread a 4-40 nut on the eyelet. Slide a silicone clevis
retainer on the 4-40 clevis, then thread the clevis on the
eyelet so the threads are just visible between the forks of
the clevis. Tighten the nut against the clevis using pliers to
prevent the clevis from vibrating loose. Use threadlock on
the clevis and nut as well.
10. Attach the clevises to the middle holes on the
steering arm, then slide the clevis retainers over the forks of
the clevis to make sure they don’t open accidentally. Check
that the cables will not cross in the rear of the fuselage when
the tail wheel is installed.
After initial test flights, you can move the
clevis in or out to obtain the desired amount
of tail wheel throw. Moving the clevis in will
increase the amount of throw, while moving the
clevis out will decrease the amount of throw.
11. Mount the tail wheel assembly in the fuselage
using four 4-40 x 1/2-inch socket head screws and four #4
washers to attach the mount to the fuselage. The mount
only fits in one direction, so rotate it until all four holes are
aligned. The bracket is attached using two 4-40 socket head
screws and two #4 washers. Use threadlock and a 3/32-inch
hex wrench to tighten the screws.
12. Measure from the front edge and the sides of the
opening in the fuselage to locate the tail wire. Transfer the
measurement to the cover, then use a pin vise and 1/8-
inch (3mm) drill bit to drill a hole in the cover. Fit the cover
and enlarge the hole using a hobby knife and #11 blade as
necessary so the tail wheel wire is centered in the hole when
the cover is in position.
13. The cover is secured to the fuselage using five M2.5
x 12 sheet metal screws. Use a pin vise and 1/16-inch
(1.5mm) drill bit to drill the holes. Use a felt-tipped pen
to mark the position of the former on the fuselage so the
screws can be located when they thread into the former. Use
a #1 Phillips screwdriver to install the screws.
