Flight Modes
The EX4 has the following flight modes:
Position Mode:
When the aircraft is in GPS mode, it can achieve accurate hover of the aircraft. When the GPS
signal is weak, the aircraft will automatically enter Altitude Mode or vision positioning mode.
Altitude Mode:
In Altitude Mode, when the visual positioning conditions are satisfied, the aircraft will automatically
enter the visual positioning mode,in the visual positioning mode, the aircraft can hover stably with
the vision positioning system.
When the visual positioning condition is not satisfied, the aircraft will hold the current altitude by
barometer. Accurate hover can not be achieved, as the aircraft has possibility to drift horizontally
and it requires user with skilled flight control.

Return to Home (RTH)
Aircraft has Return-to-Home (RTH) function, and there are 3 types of RTH: one-key RTH, low
battery RTH and lose control RTH. When the GPS signal is good and the aircraft successfully
records the return point, if the user turns on One-key RTH, or the aircraft triggers low battery RTH,
or the communication signal between the remote controller and the aircraft is lost, the aircraft will
automatically return to the return point and land.
Before the aircraft takes off, when the aircraft status indicator turns green and the GPS mode is
displayed on the APP, the current position of the aircraft will be recorded as the return point.

One Key RTH
When the GPS signal is good (the aircraft status indicator is solid green), the aircraft can return to
the return point via the “ ” button on the remote control, and the return process is the same as
lose control RTH. The difference is that when the aircraft returns and begins to land, the user can
control the aircraft through the joystick to avoid obstacles and change the landing position. After
pressing and holding the “ ” button for more than 2 seconds to exit the return, the user can
regain control of the aircraft.
Low Battery RTH
During the flight, when the red light of the aircraft status indicator flashes slowly, the aircraft
triggers low battery RTH. During the landing, the user can control the aircraft by joystick to avoid
obstacles and change the landing position.
Lose Control RTH
When the GPS signal is good (the aircraft status indicator is solid green), the compass is working
normally, and the aircraft successfully records the return point, if the remote control signal
continues to be lost for more than 2 seconds, the flight control system will take over the control of
the aircraft and control the aircraft to fly back to the last recorded return point. If the signal of the
remote controller is restored later during the flight, the return process will continue, but the user
can cancel the return and regain the control of the aircraft through the RTH button “ ”.
Attentions
：
● The aircraft cannot avoid obstacles when it is flying back during the RTH process.
● The aircraft cannot return to the Return Point if the GPS signal is weak or unavailable.
● During RTH process, when the aircraft is flying above 30 meters, the aircraft will
immediately perform the RTH function; when flying below 30 meters, the aircraft will rise to
30 meters automatically and then perform the RTH function.
● If the aircraft does not receive the satellite signal or the signal of the remote controller
continues to be lost for more than 2 seconds, the aircraft will not be able to return, and will
slowly descend until it lands.
Vision Position System
Consisted by ultrasonic sensor①and camera②,The vision system is composed by vision
sensor and ultrasonic sensor, The position information of aircraft can be obtained by vision sensor,
and the current height can be judged by the ultrasonic sensor, so that the precise positioning and
safe flight of aircraft can be ensured.

Vision Positioning System
The Vision Positioning System is typically used in indoor environment when GPS is weak or
unavailable. It works best when the aircraft altitude is less than 3 meters.
The precision of the vision system is easily affected by the light strength and features of the surface
textures. It would happen if the ultrasonic sensor could not work normally to detect the
altitude when it is flying over objects that is made by sound-absorbing materials. Once the
vision sensor and ultrasonic sensor are both not available, aircraft will switch to altitude
mode automatically. Be cautious to operate the aircraft in the following situation:
● Fly fast at an altitude below 0.5m.
● Fly over monochrome surfaces (like pure black, pure red, pure red and pure green).
● Fly over strong light reflective surfaces or surfaces prone to reflection.
● Fly over water or transparent object surfaces.
● Fly over moving object surfaces (such as crowds, swaying juggles and glass).
● Fly over an area where light changes dramatically and rapidly.
● Fly over surfaces extremely dark (lux<10) or extremely bright (lux>10,000).
● Fly over material surfaces that absorb ultrasonic waves (like thick carpet).
● Fly over surfaces without clear textures.
● Fly over surfaces with highly repeating textures (small grid brick in the same color).
● Fly over surfaces that are tilting over 30 degrees (could not receive the echo of the
ultrasonic wave).
● Flying speed should be controlled not to be too fast. When the aircraft is 1 meter against the
ground, the flying speed should not be over 5m/s; When the aircraft is 2 meter against
ground, the flying speed should not be over 14m/s.
● Keep sensors clean at all the time.
● The vision system is only effective when the aircraft is within the altitude of 3 meters.
● Make sure that the light is bright enough and the surfaces is with clear textures so that the
vision system can acquire the movement information through recognizing the ground
