Flight Mode
The GDU O2series product supports two flight modes:
1. Standard mode (maximum flight speed: 5m/s)
Accurate hovering and smart flight can be achieved through the use of the GPS module and vision
position system.
If the GPS signal is strong, the aircraft will be positioned through GPS;
If the GPS signal is too weak, and the light levels meet the needs of the vision position system,
then the aircraft will be positioned through the vision position system;
If the GPS signal is weak and the light condition do not meet the needs of the vision position
system, the aircraft will not hover accurately, and the GDU Mini App will prompt the user to land.
2. Sport mode (maximum flight speed: 15m/s)
The aircraft will hover accurately using the GPS module. The maximum flight speed can be

14
increased by adjusting the aircraft control sensitivity.
Attention! If the sport mode is selected during the flight process, the forward vision system will
automatically shut down, and the aircraft will cease actively braking and avoiding obstacles. The
user must pay attention to the surrounding environment and control the aircraft to avoid obstacles
along the flight route.
Attention! The flight speed and landing speed of the aircraft will be higher in sport mode than in
standard mode, so the braking distance will significantly increase. In a windless environment, the
user should reserve a braking distance of 30m at least to ensure flight safety.
Attention! The control sensitivity of the aircraft will be significantly improved in sport mode. The
aircraft will respond strongly and fly far in response to even minor operations of the remote
controller. In actual flight situations, the user should ensure sufficient flying space to ensure flight
safety.
Automatic Return Home
The GDU O2series product has the function of automatic return home in three modes, i.e.
“Automatic return home”, “Low power return” and “Communication loss return.”
If a return point has been recorded successfully before takeoff, the aircraft will automatically
return and land in the takeoff area once the user triggers automatic return home mode, low power
return mode, or communication (between the remote controller and aircraft) loss control mode.
The return point, also known as the HOME point, is defined as the valid GPS coordinates recorded
at the time of takeoff or when flight conditions enjoy strong GPS signals. A return point is valid
only for the current flight.
If automatic return is triggered, the aircraft will return at the current height if the distance between
the aircraft and return point is less than 20m. Otherwise, the aircraft will rise to the preset height
(if the current height is above the set height, the aircraft will fly at the current height), fly to
directly above the return point, and then slowly land.
※Please set the return height in the flight setting interface of the GDU Mini App.
1. Automatic return home
Automatic return can be triggered during the flight process by pressing the “Return” button on the
remote controller or by clicking “ ” in the GDU Mini App interface. During the return process,
the user can press the “Return” button or click “ ” in the GDU Mini App interface to exit the
return cycle and regain active control.
2. Low power return

15
Three mechanisms are provided:low power alarm, low power return,and emergency low power
landing.
Low power alert
If the remaining power is 30% or less of total power, the low power alert will be triggered, the red
indicator will flash slowly, and the GDU Mini App will remind the user of the low power levels.
Low power return
If the remaining power is 20% or less of total power, the aircraft will be forced to return
automatically. During the return process, the aircraft can be controlled by remote controller
(assuming standard signal levels).
Emergency low power landing
If the remaining power is 8% or less of total power, this will constitute a power emergency, and
the aircraft will be forced to land vertically.
※The throttle lever can be adjusted to position the aircraft into a more appropriate position before
landing.
※If the battery power is too low for the aircraft to return, the user should immediately land the aircraft.
3. Communication loss return
If the GPS signal is strong, and the compass is operating normally, then a return point will be
successfully recorded by the aircraft. If the remote controller’s signal is interrupted, the aircraft
will remain hovering. If the duration of signal interruption exceeds 3s, the aircraft will
automatically return. Under WIFI control, if the duration of APP signal interruption exceeds 30s,
the aircraft will then also return automatically. If normal signal conditions are recovered during
the return process, the aircraft will continue returning, but the user can press the “Return” button
on the remote controller or click “ ” on the GDU Mini App interface to exit the return
process.
※WIFI control is only applicable to GDU O2.
Vision Position System
The vision position system includes the forward vision system and the downward vision system.
The forward vision system on two sides of the nose includes two lenses, and used for sensing
obstacles by visual distance identification. The downward vision system at the bottom of the
aircraft includes optical and ultrasonic sensors, and used to obtain the location information of the
aircraft with optical sensor to provide the location reference along the horizontal axis. The current
flight height can be judged through ultrasonic sensor, thus providing a vertical height reference
and allowing flight at a fixed height.

16
Observation Range
See the figure below for the observation ranges of the forward vision system and downward vision
system. If obstacles exist outside these ranges, the aircraft cannot effectively avoid them; please
fly carefully.
Downward Vision System Application Scenario
The downward vision system is effective with height less than 3m, in poor GPS signal conditions.
It is particularly applicable to indoor flight.
Operating Steps
1. Use the remote controller to switch the flight mode into standard mode.
2. Turn on the aircraft’s power supply. Wait until the flight status indicator is a steady green ON.
3. Engage the sticks to start the aircraft. The downward vision system will work automatically
without requiring manual activation.
Forward Vision System Application Scenario

17
The forward vision system is available in standard mode under well-lit conditions, and can be used
for observing and avoiding clear obstacles during flight.
The accuracy of the vision position system is likely to be influenced by light intensity and
surface of obstacles, and ultrasonic positioning may be inaccurate if the drone flies close to
sound-absorbing materials. Therefore, be careful not to rely on the vision position system in
the following conditions:
Light intensity: less than 10lux or more than 10,000lux.
Operating temperature: below -10℃or above 55℃.
Flight altitude: more than 4,000m.
Excessively flight speed.
Pure color surfaces (such as pure black, pure red, pure white and pure green).
Highly reflective surfaces.
Near water or transparent objects.
Surface of moving objects.
Strong or rapid changing light.
Surface with strong ultrasonic absorbing objects.
Surfaceswith no clear textures.
Surface with highly repetitive or patterned textures.
Surface sloped at more than 30 degrees.
Small obstacles (area: less than 1m2).
Smart Flight Function
Pay attention to the following items before enabling the smart flight function:
1. Ensure good light conditions.

18
2. Ensure that the cameras of the forward and downward vision systems are clean and free of
blemishes.
3. Ensure that the aircraft is fully charged and in standard mode.
4. Ensure that the power-on self-check results of the GDU Mini App comply with the preflight
requirements.
5. The aircraft should fly more than 3m above the ground after the Follow/Around function is
enabled.
6. Always pay attention to surrounding objects along the aircraft’s Follow/Around route, and be
ready to switch to manual control or click “STOP” on the GDU Mini APP to avoid collision in
case of emergency.
7. Pedestrians should be kept more than 5m away from aircraft in Follow/Around mode.
8. Be careful when enabling the Follow/Around function if the target is moving significantly or is
beyond visual range.
9. Communication may be interrupted in the complex outdoor electromagnetic environment. In
case of communication interruption, then safely approach the aircraft. If possible, click
“Automatic return home” to prevent the aircraft from losing control as a result of the ensuing
communication loss.
10. Please observe the local laws and regulations regarding privacy while using the Follow
function.
11. If the gesture shot function is enabled, the aircraft should be hovered at about 3m away
from the main user and at aheight of less than 1.5 times the height of the main user.
