Assemble the Tail Pitch Control Slider and Pitch Control Fork
according to the drawing as follows. Insert No. 9 Bearings into
No. 11 Tail Pitch Control Slider. Add a tiny drop of Loctite on
the "outside" surface of No. 17 Tail Pitch Control Bushing, then
slide it into the two bearings in the No. 11 Tail Pitch Control
Slider. Thread the No. 19 Metal Pitch Control Fork onto the
brass bushing until the bushing does not have any in and out
play, but the pitch fork should still be able to spin freely in the
bearings. Add a No. 12 Link Ball with a No. 5 Screw. Then
slide the finished pitch slider onto the tail shaft.
Now assemble the Tail Blade Grip System. First install the No.
16 Tail Rotor Hub onto the No. 18 Tail Rotor Shaft. The hub
will be almost flush with the end of the tail rotor shaft. Secure
the hub to the shaft by using two No. 2 M3x3 set screws. Add
Red Side In
Black Side Out
Warning:
Please note the assembling direction of the
angular bearing. If they are not assembled
properl y as illustrated, they will easily fail
and result in unexpected danger.

a tiny drop of Loctite on the set screw before threading them
into the hub. If too much Loctite is used then it will be impossible
to remove the set screws for service in the future. A tiny drop
of Loctite is sufficient to prevent them from vibrating out. Put
a tiny drop of Loctite on the inside surface of No. 8 Bearings.
Then slide two No. 8 bearings onto each end of the tail rotor
hub. Add the No. 6 3mm locknut.
Now add the two pieces plastic Tail Pitch Housings.
Install No. 10 Tail Pitch Control Links, No. 13 Collars, and No.
3 Screws according to the drawing.
Attach the Tail Pitch Control Links No. 10 to the Pitch Fork using
the small pins, No. 20 with E-Ring No. 7.

First slide the two support bearings over the torque tube. The
two bearings should be evenly spaced. Add a drop of thin CA
glue on the torque tube next to where the bearings are. Then
quickly slide the bearings over the CA glue. This will hold the
bearings in place.
Space the two bearings so the distances A,B,C are
approximately the same.
