screen.
Note:
When using the governor function, be sure
to make each setting of "Governor Basic".
Note:
After completing the linkage of the throttle,
be sure to set the "Servo limit point setting" first,
and then set the other functions.
(1) Governor: Governor active
Set the governor operation mode of CGY. The initial setting is "ACT (active)"
where, as the designation implies, the governor is active. If you do not want
to use governor, select "INH (Inhibit)".
Setting: ACT (Active) / INH (Inhibit) Initial setting: ACT
(2) Gear Ratio:
Input the main rotor gear ratio by pushing the "Gear Ratio" button to select
the desired working mode.
Setting ranges: 1.00 ~ 50.00 t Initial value: 8.00 t
Notes:
• If the gear ratio is not properly set, the
set speed and actual engine speed will
be different.
• The gear ratio should be given in the
helicopter instruction manual. If the
helicopter instruction manual does not
give the gear ratio, calculate the gear
ratio as follows:
Rotor
main gear
N1
Engine
pinion gear
N2
Gear ratio = N1/N2
Carry values less than 1/1000 to the
next whole number.
(3) Pole Num.: Pole number
This parameter is used when using a direct phase sensor attachment to a
brushless motor lead. Input the motor pole count as specified by the brush-
less motor manufacturer. When using any revolution sensor other than a
direct phase sensor type, set the pole number to 2 p.
Note
: For nitro use, set to 2 p.
Note
: The input signal range of the CGY is 0.0 v - 3.0 v. Exceeding this volt-
age range may cause damage to the CGY.
Setting ranges: 2 -24 P Initial value: 2 P
(4) Servo Type
Select the throttle servo type. Digital servos offer the best response.
Setting: Analog / DG:1520 Initial setting: Analog
WARNING
The servo type parameter within the CGY must match the type of
servo you are using. Incorrect settings may damage the CGY or the
servo. An incorrect setting may also result in the loss of control during
flight.
(5) RPM set.: RPM setting
Setting the main rotor RPM. This is calculated by engine revolution with
the gear ratio of the main shaft.
When the rotation speed can be set with the governor mixing function of
the transmitter, it is necessary to first match the display rpm value of 1-2-3
of "RPM Set" with the display rpm value of the transmitter.
Setting ranges: off / 700 ~ 4,000 rpm Initial value: 1,000 rpm
*To set lower than 1,000 rpm, set "Low. Revo" of "Governor Expert" menu to 700
rpm.
