(5) THR. Mode: Throttle data mode
This parameter selects the throttle input operation. Pressing the [ /+] or
[ /-] key will change the mode.
Optimize:
CGY sets the throttle input signal to optimum. There is no need to con-
sider the throttle curve setting on the transmitter.
Fixed:
This is the suggested mode for use with electric motors. This setting ensures
that there is a fixed throttle input as is related to the helicopter revolution.
Tx.Curve:
If this mode is selected, the CGY uses the exact throttle input from the trans-
mitter. As such, the throttle curve setting on the transmitter is required.
Note:
when the Rev.Lmt mode is selected, this mode should also be selected.
Setting: GOVERNOR / Rev. Lmt Initial setting: GOVERNOR
(4) Yaw. Comp: Governor working mode
Yaw compensation allows the governor to more rapidly correct for
changes in power demands of the model resulting from yaw input. Set the
mode to match the gyro installation direction. Select from: CW/TOP, CW/
BOTM, CCW/TOP, CCW/BOTM by pressing the [ /+] or [ /-] key.
Note:
if
the user has selected the governor only mode, this parameter is inhibited.
Revolution fluctuation in the case of pirouettes
The governor detects the rpm via the revolution sensor mounted in the
engine section. During a pirouettes, the helicopter itself rotates, so that its
pirouettes speed is added (reduced) to the engine speed. Therefore, the
main rotor speed will fluctuate accordingly. Since the CGY has a gyro, it
can accurately measure the pirouette speed. The yaw rate correction is
thus determined by a combination of gyro function and governor function.
CW:
clockwise rotor direction
CCW:
counter clockwise rotor direction
TOP:
Gyro top/name emblem facing up
BOTM:
Gyro top/name emblem facing down
Setting: CW/TOP, CW/BOTM, CCW/TOP, CCW/BOTM Initial setting: CW/TOP
