Move the hovering pitch knob (CH6) and the
hovering throttle knob (CH7) to the center
positions (if these functions are activated in the
Advance Menu, the knobs may be moved in flight
to make adjustments). Next, input pitch curve
data so that the normal pitch used in hovering
varies between -2.5° and +10°.
The pitch angle should be set so that the high
throttle pitch rate is large. This provides high
collective sensitivity to help cope with windy
conditions.
The following values are recommended
starting points for the pitch curve:
Point
1 2 3 4 5
Setting
(%) 15 25 55 75 90
Blade pitch -2.0°
+4.5°
+10°
10. Revolution Mix Setting
Revolution mixing uses the tail rotor to
suppress the torque reaction of the main rotor due
to changes in collective pitch. Call up the
REVOLU NORM Menu. Input the values as
follows:
Point
1 2 3 4 5
Setting (%)
-25
-12
0
+12
+25
FLIGHT CONDITION SWITCHING
Your system is already programmed to have
settings for Idle-up 1 [IDL1], Idle-up 2 [IDL2],
and Throttle Hold [HOLD] in addition to the
normal flight condition [NORM]. The menus
for these added flight conditions are contained in
the Advance Menus. Refer to the menu structure
on p. 21 for more info.
The position and ON direction of each flight
condition call switch are set as follows:
•
Normal [NORM] – for hovering. Operation
when all switches OFF.
•
Idle-up 1 [IDL1] – for 540° stall turns, looping,
rolling stall turns. ON at Switch G center
position
•
Idle-up 2 [IDL2] – for rolling aerobatics. ON
at Switch G forward position.
•
Throttle Hold [HOLD] – for autorotation. ON
at Switch E forward position.
We recommend that you fly the model and
adjust trims and control responses to your liking in
hover before setting up another flight condition.
To set the condition data for each flight
condition, be sure that you call the appropriate
condition by turning on the correct switch (as
given above). Double-check to be sure that you
are setting the menu you desire.
As mixes are switched on or off, HOLD has
highest priority, followed by IDL2, IDL1, and
NORM.
Idle-Up 1 Settings
The settings for IDL1 conditions are among
those contained in the Advance menus (see the
menu structure on p. 21 for more info).
11. Throttle Curve Setting: move to the TH-
CRV IDL1 menu and activate it. Change the
Idle-up 1 throttle curve points to the values shown
below:
Point
1 2 3 4 5
Setting
(%) 57 55 57 75 100
12. Pitch Curve Setting. Move to the PI-CRV
IDL1 menu and activate. The Idle-up 1 pitch
curve should use the same curve as the normal
condition except with the maximum high throttle
pitch angle between 8° to 10°, depending on the
engine used.
Point
1 2 3 4 5
Setting
(%) 10 25 50 65 80
Blade pitch -2.5°
+4.5°
+8°
13. Idle-up 1 Revolution Setting:
These settings are used in 540° stall turns,
looping, and rolling stall turns and are set to be
straight ahead when the model is pointing directly
into or away from the wind. Move to the
REVOLU IDL1 menu and input the following
values:
Point
1 2 3 4 5
Setting (%)
-20
-10
0
+10
+20
Idle-Up 2 Settings
The settings for IDL2 conditions are also
among those contained in the Advance menus
(see the menu structure on p. 21).
