Now that the radio system is completely installed into the helicopter, it is
necessary to check and adjust the following:
1. SERVO DIRECTION (SERVO REVERSING)
Check to insure that all servos have been set to the correct direction
as shown on page 24.
2. DUAL RATES
It is suggested that for initial flights the dual rate function values be
set as follows:
0 Position (low rate): 60%
1 Position (high rate): 100%
3. EXPONENTIAL SETTINGS
It is suggested that the exponential rate settings remain in the 0 value
position until the initial test flights. After initial flights, adjust the
exponential values to achieve the desired control feel.
4. SUB-TRIM SETTINGS
It is suggested that the correct neutral settings be achieved without
the use of the sub-trim feature. If sub-trim is used for final flight
adjustments, it is suggested that the sub-trim values not exceed 10. If
the sub-trim values are greater, readjust the control linkages and reset
the sub-trims to 0.
5. PITCH/THROTTLE CURVE ADJUSTMENT
It is very important that the throttle and pitch curves are adjusted
properly to achieve the best performance from your helicopter. When
properly adjusted, the main rotor rpm should remain consistent
throughout all maneuvers and throttle stick positions. A constant rpm
will also help to improve the effectiveness and accuracy of the tail
rotor and gyro systems.
A. PITCH CURVE ADJUSTMENT
It will now be necessary to adjust the main rotor blade pitch to match
the settings shown in the chart. A main rotor blade pitch gauge (sold
separately) will be necessary for this procedure. Prior to setting the
main rotor blade pitch, it will be necessary to first set the required
blade pitch at

(center) stick. Turn the system on and set the collec-
tive pitch stick to the center position as in previous steps. If all link-
ages are properly adjusted, the swashplate/rotor head system should
appear as shown in the diagram below. Please note that at the center
pitch position, the seesaw mixing arms located on the rotor head are
parallel (level) to the seesaw shaft/flybar assembly.
If your seesaw mixing arms are not level as shown, adjust the 2 see-
saw arm to swashplate control rods as needed.
Once the position of the seesaw mixing arms have been established,
attach a main rotor pitch gauge (sold separately) to one rotor blade and
check the current pitch setting. The current pitch should be approximately
8 to 9°. If the pitch is slightly less or more, this can be adjusted later
through the radio’s pitch curve function. Attach the pitch gauge to the sec-
ond main rotor blade and match the pitch at this time.
