AGRAS MG-1 User Manual
Ensure that the GPS signal is strong (GPS count ≥ 6) when using the operation resumption
function. Otherwise, the aircraft cannot record and return to the stopping point.
The stopping point will be updated as long as the Operation Mode Switch is toggled from
Smart Operation Mode to any other mode or RTH (Smart RTH or Failsafe RTH) is triggered
Follow the instructions below to use this function:
1. Toggle the Operation Mode Switch to exit Smart Operation Mode or initialize the Failsafe RTH or
Smart RTH procedure. The current location of the aircraft will be recorded as the stopping point.
2. Fly the aircraft to a safe location before resuming the operation. If the radar module is enabled,
adjust the spraying distance between the aircraft and the vegetation to be within the working
range (2 – 3.5 m). Refer to the Altitude Stabilization System (p. 30) for details.
3. Ensure that the aircraft is in P-mode and the GPS signal is strong enough (GPS count ≥ 6).
Toggle the Operation Mode Switch to enter Smart Operation Mode. The aircraft will return to the
recorded stopping point automatically and resume the operation.
System Data Protection
The System Data Protection feature enables the aircraft to retain vital system data (e.g. the positions
of Point A, Point B and the stopping point) for about 1 minute after the aircraft is powered off.
Retaining vital system data allows the aircraft to resume operation after a short, temporary pause.
Follow the instructions below to use this feature:
1. Toggle the Operation Mode Switch to exit Smart Operation Mode. The current location of the
aircraft will be marked as the stopping point.
2. Land the aircraft and stop the motors.
3. System Data Protection is triggered automatically once the aircraft is powered off. The Aircraft
Status Indicator will glow solid green to show that System Data Protection is successfully
triggered.
4. Replace the battery within the 1 minute window.
5. Restart the aircraft and toggle the Operation Mode Switch to enter Manual Operation Mode.
6. Ensure that the aircraft is in P-mode and the GPS signal is strong enough (GPS count ≥ 6). Start the
motors and elevate the aircraft to a safe altitude. Adjust the spraying distance between the aircraft
and the vegetation, so that the value falls with the range of 2 to 3.5 meters. Refer to the Altitude
Stabilization System (p. 30) for more details.
7. Toggle the Operation Mode Switch to enter Smart Operation Mode. The aircraft will y back to
the previously recorded stopping point and resume its operation
The system data can only be retained for 1 minute. DO NOT power off the aircraft for more than
1 minute if you want to resume operation because the system data will be lost.
Manual Operation Mode
Toggle the Operation Mode Switch to enter Manual Operation Mode. You can control all the
movements of the aircraft, spray liquid via the spray button on the remote controller, and adjust the
spray rate via the dial on the remote controller. Refer to Controlling the Spraying System (p. 18) for
more details on adjusting the spray rate. Manual Operation Mode is ideal for when the operating
area is small.
