When the drone flies on the left side, as 

shown in Figure 7, 20 meters from the 

left side of the drone is the effective 

scanning range of the obstacle avoider, 

and the scanning path is about 90° 

between the two arms on the left side. 

The same applies to the scanning range 

of the shock absorber flying backwards 

or right.

When the drone is flying, as shown in 

Figure 6, 20 meters in front of the drone 

is the effective scanning range of the 

obstacle avoider, and the scanning 

path is about 90° between the two 

arms in the flying direction.

The position where the UAV stops 

flying is determined by the flight 

speed, when the UAV is flying at full 

speed in low gear. After the drone 

scans the obstacle at 20 meters, it 

starts to calculate and issue a stop 

flight instruction. The stop position 

of the drone is determined by the 

flight speed (the faster the flight 

speed, the closer the distance 

between the drone and the obstacle, 

and the opposite flight The slower 

the speed, the farther the distance 

between the drone and the obstacle)

When the UAV encounters obstacles 

and hover in the scanning range of 20 

meters in the flying direction, the UAV 

cannot continue to fly in that direction, 

and can continue to fly after avoiding 

the obstacles or to other obstacles 

within 20 meters. In the direction of 

flight.

When the UAV takes off, there is an obstacle within 20 meters of the forward direction. The UAV cannot fly in this direction. It can continue 

to fly after avoiding the obstacle or fly in the direction of other obstacles within 20 meters.

6. If the UAV encounters an obstacle during GPS intelligent return, the obstacle avoidance device will rise to a safe height again after 

scanning the obstacle before returning.

Precautions for the installation and use of obstacle avoidance equipment:

Obstacle avoidance function and working principle

Use note:Obstacle avoidance equipment must be installed before turning on the power of the drone, otherwise it will damage the obstacle 

avoidance equipment and affect normal use.

1. Take out the cover for the 

installation position of the 

obstacle avoidance equipment

2. Insert the obstacle avoidance 

equipment as shown in the 

picture

The obstacle avoidance equipment will rotate left and right when it is 

running. Do not manually interfere with it to prevent it from rotating 

when it is rotating, otherwise the equipment may be damaged.

Special suggestion:

it is suggested that when the LED light in front of the body flashes slowly during Drone flight, the remote control makes 

a "Di" sound,it indicates that the Drone has insufficient power. When the Drone power is insufficient or loses the signal 

during flight, the aircraft will automatically enter the return mode and fly back according to the original route.

5.One-press for return 

When the drone is flying in the air, press 

this function button on the remote control 

(Figure 5), it will automatically rise or fall 

to a height of 50 meters, return straight 

and land to the take-off location.

 One-press for return

When turning on this product, do not touch the obstacle avoidance equipment, because the obstacle avoidance equipment is in the power-on 

working state, unauthorized touching will cause the obstacle avoidance equipment to not work normally, and it will most likely damage the 

obstacle avoidance equipment function.

When removing the obstacle avoidance equipment, the power of the drone must be turned off before dismantling, otherwise it will damage 

the obstacle avoidance equipment and affect normal use.

The product is turned on by default in low-speed mode (50%). The drone has 360° obstacle avoidance function, such as switching to high-

speed mode (100%). Because the aircraft is flying fast, the system has not received the instruction to stop the flight. The aircraft may have 

hit an obstacle, and the UAV's obstacle avoidance function automatically fails.
