3. Enlarge the hole through
the 1-3/4" [44mm] tail wheel
with a #11 [4.8mm] or 13/64"
[5mm] drill. Install a 13/64"
[5mm] thick spacer (included
with the Fw190) on each side
of the tail wheel. Install the tail
wheel in the strut. Be sure to
apply a drop of threadlocker
to the two mounting screws.
❏
4. Insert an .080 ball link
ball in both holes of the
steering arm. Secure each ball
with a .080 nut and a drop of
threadlocker.
❏
5. Slide a small copper tube (called a swage) over
one end of the .020 x 80" [.5 x 200cm] braided cables,
then guide the end of the cable back through.
❏
6. Wrap the cable back around the swage and back
through the swage.
❏
7. Use pliers to pull the cable from the fi rst loop to
reduce the size of the second loop.
❏
8. Now pull on the
long end of the cable to
reduce the size of the
fi rst loop. Slip the loop
over one of the ball link
balls on the steering arm.
Tighten the loop until it is
small enough to remain
secure on the ball, yet
may still be pried off.
Squeeze the swage with
pliers. Connect the other
cable to the other ball
link ball the same way.
❏
9. Place the tail gear in the fuselage while
simultaneously guiding the pull/pull cable through the
white plastic guide tubes.
❏
10. Drill four 3/32" [2.4mm] holes through the rails
for mounting the tail gear.
If your drill bit is not long enough to reach the rail nearest
the top of the fuselage, use medium CA to temporarily
glue a 3/32" [2.4mm] drill bit in a 1/8" [3.2mm] brass
tube. After drilling the holes, the drill can be removed
from the tube by heating the tube.
❏
11. Mount the tail gear in the fuselage with four #6
x 1/2" [13mm] sheet metal screws. Harden the screw
holes with CA.
❏
12. Install the tail wheel steering servo in the center
of the servo tray. Remember to harden the screw holes
with thin CA.
