6. AFR (D/R)
AFR (D/R) function is used to adjust the throw
and operation curve of aileron, elevator and rudder
for each condition.
*For throttle and pitch curve settings, refer to the above-
mentioned "Throttle/Pitch curve setting"
This is normally used after End Point has defined
the maximum throw directions.
7. Gyro sensitivity and mode switching
The gyro sensitivity and mode switching
function is dedicated gyro mixing of the Model
Menu, and can be set for each condition.
●Normal condition (hovering): Gyro sensitivity
maximum
●Idle up 1/Idle up 2/Throttle hold: Gyro
sensitivity minimum
●However, at auto rotation of a tail-driven
helicopter, this function may not have any
effect at high gyro sensitivity.
8. Pitch to RUD mixing setting
Note: When using a GY601, GY502, GY401,
or other heading hold gyro, this Pitch to RUD
mixing should not be used. The reaction
torque is corrected at the gyro side. When
operating the gyro in the AVCS mode, the
mixed signal will cause neutral deviation
symptoms and the gyro will not operate
normally.
Use this function when you want to suppress
the torque generated by the changes in the pitch
and speed of the main rotor during pitch operation.
Adjust it so that the nose does not swing in the
rudder direction. However, when using a heading
hold gyro like those shown below, do not use Pitch
to RUD mixing.
Call the Pitch to RUD mixing function from the
Model Menu, and set the curve for each condition.
(At initial setting, this function is in the "INH"
state. To use it, set it to the "ON" state.)
<Setting example>
Call the mixing curve of each condition with the
condition select switch.
1. A curve setting example is shown below.
●Pitch to RUD mixing curve (Normal)
Use the hovering system and set this curve to
match take off and landing and vertical climb at
a constant speed.
*For this curve, use the initial setting [EXP1] curve type.
●Pitch to RUD mixing (Idle up 1)
Use this curve in 540º stall turn, loop, and rolling
stall turn, and adjust it so the fuselage is facing
straight ahead when heading into the wind.
*For this curve, [EXP1] curve type can be used and the entire
curve can be lowered with the [Offset] function.
●Pitch to RUD mixing (Hold)
This function is set so that the fuselage is facing
straight ahead at straight line auto rotation. The
pitch of the tail rotor becomes nearly 0º.
*For this curve, [EXP1] curve type can be used and the entire
curve can be lowered with the [Offset] function.
●Other settings
The mixing rise characteristic at pitch operation
can be adjusted. An acceleration function which
temporarily increases and decreases the mixing
amount can be set.
9. Throttle hold setting
*If throttle hold is necessary, please refer to the THR HOLD
function.
10. Throttle cut setting
Throttle cut provides an easy way to stop the
engine, by flipping a switch with the throttle stick
at idle. The action is not functional at high throttle
to avoid accidental dead sticks. The switch's
location and direction must be chosen, as it defaults
to NULL.
*With throttle stick at idle, adjust the cut position
until the engine consistently shuts off, but throttle
linkage is not binding.
