From parts bag 1: Iznsert
the Feathering Shaft into
the head block, slide one
M6X10 Washer on each side of
the shaft. Install the blade grip (
Note
the direction of the bell mixer arm
)
followed by one M8x13 Washer,
one M6x12 Thrust Ball Bearing
(
install the first steel washer
(large inside diameter)
followed by the ball race,
remember to grease the ball
race, followed by the second
steel washer (smaller inside
diameter)
and one M5
Locknut. Tighten the
locknut, using the glow
plug socket wrench on
one nut while holding
the other with pliers,
tighten the nuts until both blade
grips turn freely without any excessive end
play. Assemble Pushrod I x 2, according to the
table in the box, measuring 26mm center to center following the diagram on
page 30, and connect the seesaw ball to the long ball on the bell mixer.

insert the slide
tube into the bell mixer arm (
Note:
the oilite bearings
are pre-installed
) and secure
onto the blade grip with one
M3x16 Socket Cap screw and
M3x7 Flat washer.
R50
install
one Long Ball and one Short Ball (
Tip

into the Bell Mixer, press one
3x7mm Ball Bearing into one side
followed by one 3x5mm spacer and the
one more bearing from the opposite
side. Insert one M3x16 Socket Cap
Screw (
Tip 4
) through the arm (make
sure the flush side faces out) with one
3x5x0.5 Washer being careful not to
overtighten the screw. File the bolt
flush to the inside of the blade grip
mount. Install two M6x13 Ball Bear-
ings into both ends of the blade grip
assembly. Complete the second blade
grip in exactly the same way.

Travel Adjustment ( endpoints )
Using endpoints to adjust to the limits of how far the servo is allowed to move is very convenient for fast set-up.
If binding occurs simply reduce the travel in that direction. ** Note: by changing one side only (high or low
stick) the servo travel is no longer linear which will tend to make that control surface unstable. It is better to set
the high/low adjustments the same, or make actual pushrod adjustments.
Sub Trims
The sub trims on the outside of
your transmitter are used to fine
tune the servo center positions
while testing or in-flight. If the
trim has to be moved more than
2-3 divisions then readjust the
linkage length to set the trim
back in the center.
Exponential
The exponential function
allows adjustment of how
sensitive the cyclic controls are
when the machine is hovering.
This should be left at 0%
(linear) until all trimming is
complete.
Pitch & Throttle Curve Adjustments
The ultimate goal for adjusting the curves on your heli-
copter is to reduce how much the tail rotor moves during
flight and aerobatics. This leads to maintaining a consis-
tent main rotor RPM which can only be achieved through
adjusting the individual values which control the pitch
and throttle at a given stick position.
Dual Rates
For beginners ( using the flybar weights )
the dual rate values should be set at 100%
for both switch positions until hovering
has been mastered.
Normal position:
(high rate) 100%
Switch position 1:
(low rate) 75%
Now that the servo installation into the helicopter is finished the following pages should be reviewed. As
various types of radios can be used to setup the helicopter, some of the following information may not apply.
Final Adjustments - Radio Setup
Pitch Curve Adjustment
The following chart shows the values for the collective
pitch measured in degrees which are made on the heli-
copter using a pitch gauge. The Travel Adjustment
function (if available makes these settings easy).
For the beginner it is recommended to set the low stick
position to 0 degrees to avoid damaging the helicopter
while reducing the power during the first few flights.
These settings will need slight adjustment to keep the
helicopter at a consistent height at mid stick.

Note** In order to avoid binding at high pitch angles the flybar control
arms need to be reset at an angle of 10-15 degrees down from parallel.
Servo Direction (Servo Reversing)
Check that all servos move in the correct
directions, see the diagrams on pg 31-34.
