The Third Step (Flight):
1. Connect the drone battery(usually 2x6S in series)to power the drone.check the aircraft status, let the
drone take off and hover at 5m above the ground by using backup battery.long press the cable power
button for 3s；the cable is in power-up state, initial voltage is 395Vdc；Max.compensating voltage is 430Vdc.
Always pay attention to whether the aircraft battery voltage is within the reasonable range of 46.5~49vdc；
the recommended voltage is between 47.3vdc and 48.3vdc, enough for a force-landing.
2. When the aircraft is at 20m above the ground,adjust the winch control knob to 3 or 3.5 position；to make
the cable straight(adjust slowly, prevent the winch from pulling the cable too fast to pull the aircraft or the
cable). Let the aircraft descend 2~5m to see if the winch automatically retracts the cable to make sure the
winch can automatically retract the cable later. Different aircraft has different load capacity, the torque is
also different, normally the winch control does not exceed 4th gear , Max.6.5, and the factory setting is 600r/
min.
1.；Current Voltage: Power Off Status
2.；Current Voltage: Ground output Voltage 395V
Power on status.
3. Please stay to observe the stability of the system and the aircraft when the aircraft reaches 50m；80m；
95m；100m . If all goes well,the drone can continue to fly for a long time.
4. When the cable extends to 95 or 100 meters,display alarm and buzzer scream set in this system will be
triggered；press the cable power button to cancel the alarm). Because the scene environment is noisy,
the alarm may not be noticed, so please pay attention to avoid cable length over 110m, the length should
be strictly controlled within 100m, which prevents the cable from breaking, which is not covered by the
warranty.
