HEAD ASSEMBLY
Pushrod assembly (parts 2 through 4) is already assembled but check that the length is
actually 47mm (center to center). As the pushrods are built and installed they should be
checked for tightness. Press one ball link onto each double studded steel ball, making sure
that pressure is applied from the side of the ball link with circle mark. While holding one fly-
bar control arm, apply a small amount of slow cyanoacrylate glue and thread one end of the
double studded steel ball into each standoff. When it becomes difficult to turn with fingers,
apply slow CA to the threads and start screwing in the tapered control arm stand-off on
the other end of the ball. Slide and center the flybar through the head assembly. Care-
fully look at the flybar control arm assemblies from the previous step and notice
that when installed correctly, the securing set screw is on top. Insert one
M4x6x0.5 micro washer #CNLR1006 against each bearing then slide
the control arm halves onto each side, so that they match togeth-
er and the set screw remains on top. Insert one M3x12 but-
ton head socket screw to secure the opposite standoff.
Hold the tapered standoff using pliers while tight-
ening the screw as the rotor head
rotates clockwise.
Apply a small amount of cya-
noacrylate glue to the special
long thread ball.
All ball links are molded to be in-
stalled in only one direction. Look
carefully at the hole for the ball
as that side is 1mm larger .
Loosely tighten the M4x5 set screws into the round aluminum inserts aligned with the
flat spots on the flybar. Tighten both set screws, one at a time using Blue threadlock.
Make a pencil mark 5mm past the threads on both ends of the flybar. Thread the flybar
paddles onto the flybar until the mark is reached and align the paddles parallel. Again
using the ruler, rotate one paddle or the other to get equal distances while remembering
the leading edge of the paddles turn clockwise.

HEAD ASSEMBLY
Press one M3x7 flanged ball
bearing into one side followed
by one M3x5 spacer and another
flanged bearing from the opposite side.
If the bearing is tight, lightly sand the bell
mixer and use Red threadlock to bond the
bearing in place. Install the CNLR1014 short
steel ball into the single hole side of the bell mixer
and install the CNLR1020 medium steel ball using
Blue threadlock. Install the medium steel ball accord-
ing to the table to suit your flying preference. Use the
center hole for sport flying. Make two assemblies.
Using an available M3 screw, carefully form the
threads in the blade grip arm. Slide the M3x18
special socket shoulder screw through the bell
mixer arm from the flat side, add one M3x5x3
spacer and apply a drop of Slow Cyanoacrylate
glue or Epoxy glue to the end of the threads
before installing into the blade grip. Tight-
en the bolt until there is no end to
end movement, but do not
overtighten the bolt as
you can strip out the
hole. Make two as-
semblies.
HI6181A (red) head dampers are for sport flying. 3D and aerobatic pi-
lots should install the hard HI6181B (black) head dampers. Press in the
head dampers into the rotor head block. Lubricate the inside surface of
each damper with light oil. Press one M8x16 ball bearing into both
ends of each main rotor blade grip. Slide
one M14 thrust washer against the bearing
closest to the main rotor blade. Make sure
that the bearing and the thrust washer
are properly seated into the deep end of
the blade grip. If necessary use a sock-
et that matches the outside diameter
of the bearing and press into posi-
tion. Make two assemblies.

CLUTCH SHOE TO FAN AND HUB MOUNTING
Apply light oil to the Torrington bearing in the center of the clutch shoe. Be sure that
no grease contacts the edge of the clutch or it could get transfered to the clutchbell.
Slide the clutch shoe onto the fan hub, press down and install four M4x8 button head
screws using Blue threadlock.
Dip a cloth in rubbing
alcohol and degrease
the threads in the end
of the engine crank-
shaft. Apply liquid oil
to the outside taper of
the engine crankshaft,
the entire taper should
be coated. Do not get
oil into the internal
threads. Use Triflow
or equivalent oil.
Slide the cooling fan assembly onto the engine. Locate the M6x15 socket
cap screw. Thoroughly clean this screw to remove any oil residue. Install
the fan assembly onto the crankshaft. Using a cloth wrapped around the
outside of the cooling fan held by your hand, tighten the M6x15 socket cap
screw until hand tight and check the runout of the fan assembly. Accept-
able runout is 0.002”, if more, remove the fan assembly and install again.
Once satisfied, remove the M6x15 socket cap screw, apply Blue thread
lock and secure in place.

If you plan to install a governor, it is best to fabricate the mount for the sensor at this
time, get it fitted and set the sensor gap before the fan shroud is installed.
Tighten these bolts
until they stop and
that’s it. Do not
torque these bolts!
Using a Dremel type tool or
similar, cut away a 29mm x
5.5mm slot.
Take the time now to make sure that the clutch shoe is prop-
erly seated on the fan assembly by looking at it from the side
and making sure there is no vertical movement as you slowly
turn over the engine. Experienced modelers willdial indicate
the clutch with an acceptable amount of runout of 0.002”

cap screws will not be tightened until after
the upper frames are installed. Attached
to the coil is a black wire, this is gener-
ally not used in helicopters and should be
secured out of the way with a cable tie.

The following pages will contain informa-
tion for both the G10 & Carbon framed
versions. You may notice the frames illus-
trated may not pertain to the model you are
building. Only if there is enough of a descre-
pency between the two versions will both
versions be illustrated. Otherwise you can
assume the frames are the same except
for cosmetic differences.

FUEL TANK INSTALLATION
The fuel tank isolators have a “U” profile that need to be fitted to the fuel tank
openings on the lower front side frames. Start at the center of one edge and
work the isolator into the frame, seating the corners. Towards the end, con-
tinue forcing the rubber material until the ends butt against each other. Note
that the frames are different sizes and some trimming is necessary.
This would be the opportune time to install the J-fitting breather. You will need to drill
a hole in your fuel tank to install the breather fitting. This hole should be as close
to the corner as possible to avoid interaction with the frames. Do a dry-fit first
prior to drilling the hole. When doing this, make sure not to oversize the hole
being made as this will cause an unecessary leak. When you install the
J-fitting, it should thread into the hole. One nut will hold the fitting
on the top side and the other nut will hold the fitting from
within the fuel tank. When installing the J-fitting,
the use of a bent paperclip will help to in-
stall the nut within the fuel tank.
As you will notice the fuel tank will float
between the front lower side frames. In-
stall the M3x10x17 fuel tank spacer on
the right side frame into the center hole
with one M3x8 socket cap screw using
Blue threadlock.

Do not threadlock the frame bolts until
the upper frames are installed as it is
critical to have the clutch and clutch bell
assembly align perfectly. To accomplish
this, the frames can be shifted within the
limits of the fasteners.
Slide the front frame assembly over the
landing gear frame and insert four M3x8
socket cap screws through the lower
frames into the landing gear frame, do
not use threadlock at this time. Install
one M4x10 socket cap screw and M4
flat washer into the slot in the frame,
threaded into the side mounts on the en-
gine crankcase. Do not used threadlock
until after the upper frames are installed.

If servicing the clutch bearing it must be installed into the bear-
ing block before it is installed onto the clutchbell. Clean the inside
race of the ball bearing and the surface where the clutchbell will be
installed. Apply a small amount of Red threadlock to the top edge
of the clutchbell and press in place using a thin walled automotive
socket that puts pressure only on the inside race of the ball bear-
ing. Pressing from the outside race will damage the bearing which
is not covered by warranty. Finally, re-install the pinion being careful
not to cross the threads using Blue threadlock.
The clutch bell assembly and lower short
breaing block is pre-assembled.

The gasser kits include the regular starting shaft and hex coupler
as in all the Predator kits to align the clutch to the clutchbell.
Clean both the starting shaft and the inside race of the bear-
ing inside the clutchbell and the inside race of the top start-
ing shaft bearing. Apply a small amount of Red threadlock
positioned just above where the bottom clutchbell bear-
ing will sit on the starting shaft. Slide the starting shaft
up through the bearing blocks. Apply a small amount
of Blue threadlock to the top of the starting shaft
and slide the hex coupler in place aligning the flat
spot with one of the holes. Apply Blue thread-
lock to the the two M4x4 set screws and
tighten in place.
The hex starting system has been suc-
cessfully used with the Z231H engine
but significant wear on the hex coupler
is common. Regular replacement of the
hex coupler is normal and is not covered
by warranty. The pull start should be
used for the first start of the day. After-
wards using a heavy duty electric starter
is possible.
The clutch bell assembly and lower short
breaing block is pre-assembled. If you
notice the clutch bell and bearing block
have a loose fit, be sure to separate the
two and apply a thin coat of Red thread-
lock to the outer race of the bearing
making sure not to get the threadlock
into the inner race.
Clean the top of the pinion gear and the inside surfaces of both the upper
and lower bearings inside the clutch shaft bearing block using alcohol.
Apply a small amount of Red threadlock to the top edge of the clutch gear
where it will contact the bearing. Press the bearing block in place, firmly
seating the bearing against the top of the pinion gear.
The hex starting is not recommended for
the Z260H engine as damage can occur
to your starting equipment and helicop-
ter components.
