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

increased by adjusting the aircraft control sensitivity.

※ Please set the return height in the flight setting interface of the GDU Mini App.

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.

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

Three mechanisms are provided: low power alarm, low power return, and emergency low power

 Low power alert

 Low power return



Emergency low power landing

landing.

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.

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).

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.

landing.

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.

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.

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

The forward vision system is available in standard mode under well-lit conditions, and can be used

 Light intensity: less than 10lux or more than 10,000lux.

 Operating temperature: below -10℃ or above 55℃.

 Flight altitude: more than 4,000m.

 Small obstacles (area: less than 1m2).

1. Ensure good light conditions.

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:
