Position the rear servo mount bracket on the left side of the
mechanics just behind the main shaft, the front of the mount
has a right angle knotch beside the hole. Insert one 3x10mm
Socket Cap Screw through the servo mount and into the upper
side frames with one 3mm Locknut to secure in place. Insert
one 3x25mm Socket Cap Screw and match the 3mm Locknut
into the molded hole for the locknut in the upper frames. At
this time install the remaining 3x25mm Socket Cap Screw and
3mm Locknut into the rear-most hole in the upper frames,
leave these loose until the tail boom assembly is ready to
be installed
. Install the rear CCPM servo from the right side
so that the output shaft is facing the front of the mechanics
and and the servo flange is on the right side of the bracket.
Insert the servo screws through the grommets, the servo
mount and into the servo mount tabs, secured from the bottom
of the servo.
Step 17 Rear CCPM Servo Mount and Rudder Servo Mount
Install both CCPM front servos at this time, with the output shaft of
the servos positioned upwards and the servo flange inserted from
behind the servo mount. Using the screws provided, insert the
screws from the servo top through the grommets (insert the
eyelets between the grommet and the mount bracket) and
attach the servo mount tabs from the bottom of the servo.
Similarily position the rudder servo mount on the right side of the upper frames, noting that the right
angle knotch is now is facing the rear of the helicopter. Insert two 3x25mm Socket Cap Screws through
the two lower holes in the upper frame assembly, through the rudder servo mount and secure with two
3mm Locknuts.
Again leave these loose for now
. Insert the rudder servo similarly with the output shaft
facing the rear but the servo flange should be on the left side of the bracket.

From parts bag 2: Slide one Threaded Extension Rod through the
upper position of the tail output bearing recess and secure two round
Canopy Mounts (
Tip1 -
one per side ) using threadlock. Examine the
servo mount brackets, the rear CCPM servo mount uses the holes that
are 31.5mm apart while the rudder servo mount uses the holes spaced
at 45mm.

The next section covers setting the pushrods and servos that will control the helicopter. It is important at this
time that you review the instructions provided with your radio that controls the ccpm mixing for the 3
cyclic servos. Reviewing the radio instructions will assist you in becoming familiar with the functions that
affect the individual servos and affect the interaction of the three servos working together to control the
swashplate.
Radio Setup Procedure
1. It is best to choose a new model memory (if available) and use the Reset feature to remove any previous
settings or mixes, remember this usually also returns the radio configuration to single servo.
2. Locate and activate the swashplate mixing for 120
0
ccpm (most manufacturers set single servo by default).
3. Return both the aileron and elevator subtrims to neutral along with any hover pitch knobs to neutral.
4. Adjust the servo reversing switch to make sure the servos are moving in the correct direction, together as the
collective stick is raised. If the servo reversing does not correct the movement of a servo, there is always a
travel adjustment function inside the swashplate mixing menu. Change the default setting to be opposite, for
example, if set to +60 then change to -60 and change any servos that are affected.
5. After each servo horn is mounted, it is critical that the horn be 90 degrees to the respective pushrod.
