Hovering - Flying
G Adjust the load to leave some margin in the payload. A takeoff with the maximum payload
requires maximum horsepower and careful flying technique. An excess payload at this point
could lead to a serious accident. Therefore, hover the helicopter to check that there is an ample
margin in payload before continuing with the flight.
G Keep the distance between the operator and the helicopter within 150 m, and the flight altitude at
3 - 4 m (from the ground or from the crop). If the distance is any greater, it will prevent the opera-
tor from monitoring the posture of the helicopter and adversely affect the signal reception condi-
tions. For safety, further shorten the distance if there are any obstacles in the area. Failure to fly
the helicopter within the maximum distance limit could lead to an accident.
G Do not turn continuously while banking in one direction for more than 10 seconds, as this will
cause the helicopter to drift as if the trim has shifted.
G Do not turn in the SG mode. Because the operation method for this mode is different from other
modes, the helicopter could make an unexpected movement.
Flying - Landing
G Do not lower the throttle stick to the slowest position during a flight, as this could disrupt the
engine speed control and cause the helicopter to descend abruptly.
G If the YACS warning light or the GPS indicator light shows an abnormal condition, the helicopter
exhibits irregular behavior, or an unusual symptom occurs (such as vibration, sound, coolant
leakage, or foul odor), immediately land the helicopter in a safe area. Continuing with the flight in
this state could lead to an accident.
G Do not press the Engine Stop switch during a flight, as this will stop the engine and cause the
helicopter to descend abruptly. However, to force the helicopter to land in case of an emergency,
press the switch after making sure that it is safe to do so.
G Abort the flight or aerial application if poor weather conditions exist as described below. Failure
to do so could pose operation difficulties, which could lead to an accident. In addition, it could
adversely affect the application and the effectiveness of the sprayed chemicals.
• Wind velocity in excess of 3 m per second at a height of 1.5 m above the ground.
• Rain, fog, or lightning in the close vicinity.
G Observe the following until the engine has come to a complete stop after landing:
• Do not turn OFF the power of the flight transmitter.
• Do not take remove or replace the battery in the transmitter.
Failure to observe these precautions will trip the failsafe device (speed control turns ON auto-
matically), which will cause the engine to accelerate suddenly.
During a takeoff or landing, if the engine speed does not decrease even if the throttle stick is low-
ered to the slowest position, calmly turn the YACS control switch OFF. This symptom could occur if
a takeoff operation is aborted or if there are a considerable number of landing shocks when the
helicopter lands.
