To set this feature, call the Pitch->R udder P->R
from the Condition Menu. The Normal setting is
used during hover, so it should be set to match take-
off, landing, and constant speed vertical climbing.
Normal Setting:
Select the normal flight conditions by turning off
all the flight condition switches. Set the rudder mix-
ing curve to the following values (initial settings):
17 Rudder->Throttle
Mix
Setting
Rudder->Throttle R->T
mixing is effective in
hovering eight, nose in circle, top hat, pirouette, and
other aerobatics. It should be set so that at half-
throttle, if the rudder stick is operated, the rotor
speed is maintained to keep altitude constant.
Idle-up 1 Setting:
These settings are used in 540° stall turns, loop-
ing, and rolling stall turns and is set to be straight
ahead when the model is pointing directly into or
away from the wind. Call the Idle-up 1 flight condi-
tions by moving switch E to the 0 (center) position.
Set the rudder mixing curve to the following values:
When these values are input, the rudder is offset
at the half-throttle position.
Idle-up 2 Setting:
These settings are used in rolls. Activate the Idle-
up 2 flight conditions by moving switch E to the 1
(forward) position. Set the rudder mixing curve to
the following values:
The rudder is offset at the half-throttle position.
Throttle Hold Setting:
Throttle Hold settings are intended to keep the
model pointed straight ahead during linear autorota-
tion. The tail rotor pitch angle is nearly 0°. Set the
Throttle Hold flight conditions by moving switch G
to the 1 (forward) position. Set the rudder mixing
curve to the following values:
For normal models, commanding right rudder
should increase throttle slightly, while using left
rudder should decrease throttle slightly.
To set this feature, return to the Normal flight
condition. Press the Rudder->Throttle R->T from
the Condition Menu. Press the ACT button to acti-
vate it, and set the Left value to -10%, and the
Right value to +10%.
18 Trim Offset Setting
The Trim Offset TOF setting should be adjust-
ed for Idle-up 1 and Idle-up 2. Aileron, elevator, and
rudder are offset so that the model flies straight
ahead during normal flight.
Call the Idle-up 1 or 2 flight condition by setting
Switch E to the 0 (center) position. Press the TOF
button from the Condition menu. Recommended
settings for aileron and elevator offsets are 6% to
10%. A delay can be set with the digital trim TRM
function.
Rudder offset is set by the Pitch->Rudder func-
tion set previously, so is not set here.
Delay Settings
Set the amount of delay for each flight condi-
tion. We recommend the following settings:
Normal . . . . . . .
20%
Idle-up 1 . . . . . . . 20%
Idle-up 2 . . . . . . . 20%
Throttle Hold . . . . 60%
The delay for Throttle hold should be large, be-
cause the rudder angle changes significantly during
flight condition changes.
