Governor operation
The GY701 operates from 1000 to 3000rpm main
rotor speed. However, the engine must be running
at the set speed. The GY701 turns off the gover-
nor when the engine is starting or idling.
* Governor operation: Operation that stabilizes the en-
gine speed at the set speed.
Condition of the governor to be on
For the safety purpose, the governor is turned on
at the below the condition are satised.
The on/off switch conditions are to be off
condition at the power on.
The stick switch is on position when it is
used.
The on/off switch is on position when it is
used.
Setting speed is not Off.
The engine speed exceeds to 60 % of the set-
ting speed.
The speed sensor is working properly.
The following operations do not indicate trouble:
When engine speed rises above the set speed:
A near-vertical dive may cause the engine speed to
rise above the set speed.
Throttle operation speed and ON/OFF point:
If throttle operation exceeds 60% of the set speed and
the rotor speed rises to the set value, the ON/OFF
point may seem to differ with the operating speed.
Delay operation to smoothen the switching operation
causes this and does not mean that the ON/OFF point
has changed.
Deviation from set speed:
The GY701 stabilizes the engine speed to within +1%
of the set speed. For example, if the rotor R.P.M. is
set to 1500rpm, the Rotor R.P.M. speed will deviate
about ±15rpm. However, this poses no problem from
the standpoint of practical use.
