Now that the radio system is completely installed into the helicopter, it is
n e c e s s a ry to check and adjust the following:
1. S e rvo Direction (Servo Reversing)
Check to insure that all servos have been set to the correct dire c t i o n
as shown in Steps 7-1 to 7-5.
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 gre a t e r, readjust the control linkages and
reset the sub-trims to 0.
6. P i t c h / T h rottle Curve Adjustment
It is very important that the throttle and pitch curves are adjusted
p roperly to achieve the best perf o rmance from your helicopter.
When properly adjusted, the main rotor head rpm should re m a i n
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 below. A Main Rotor Blade Pi t c h
Gauge (sold separately) will be necessary for this pro c e d u re. Prior to
setting the main rotor blade pitch, it will be necessary to first set the
re q u i red blade pitch at 1/2 (center) stick. Tu rn the system on and set
the collective pitch stick to the center position as in previous steps. If
all linkages 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 ro t o r
head are parallel (level) to the seesaw shaft/flybar assembly.
If your seesaw mixing arms are not level as shown, adjust the 2 seesaw
a rm to swashplate control rods as needed.
E rgo 30 CCPM
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
a p p roxi5. If the pitch is slightly less or more, this can be
adjusted later through the radio’s Pitch Cu rve Function. Attach the
pitch gauge to the second main rotor blade and match the pitch at
this time.
E rgo 46 3D CCPM
Once the position of the seesaw mixing arms has been established,
attach a main rotor pitch gauge (sold separately) to one rotor blade
and check the current pitch setting. Adjust the pitch to the desire d
setting (+5 for beginner/intermediate, 0 for 3D pilots) by adjusting the
seesaw mixing arm to the main blade holder control rods as needed.
Attach the pitch gauge to the second main rotor blade and match the
pitch at this time.
