Thank you for purchasing Forever Flex drone of a modern and foldable design. A built-in Wi-Fi
FPV camera allows to shoot photos and record videos in HD 720p resolution. A modernized gy-
roscope and barometer allow for stable fl ight on a demanded height and in all directions, as well
as 360° rotation. Flex includes all functions necessary to ensure a smooth fl ight, such as: change
of control sensitivity, Headless mode, Autostart/Auto-landing. A dedicated Forever Flex mobile
application expands the capabilities of Flex drone, adding an option to transmit image from the
camera to a smartphone screen in real-time.
Before use, read the instruction manual which contains additional information about the func-
tions and directions for use. Do not attempt to repair, modify or disassemble the device on your
own. We hope that the product of FOREVER brand will meet your expectations.

4. Check if weather conditions allow fl ight.
Warning! Do not use the drone in extremely hot, cold or rainy days! Do not use the drone during
wind with speed higher than 2.5 m/s, in urban areas, near parking lots and water tanks!
Drone start
Warning! The drone may be activated or calibrated only on a straight, fl at surface. Placing
the drone on an inclined surface may prevent correct calibration.
Activation of motors and start
To activate the motors, move both levers on the remote as shown on the picture.
Manual start

Automatic start
1. Activate motors – press and hold joysticks for a moment as shown on the picture.
2. Click the auto-start button. The drone will start automatically and maintain an altitude of ap-
proximately one meter.
Regardless of the start method, the drone will automatically switch to altitude hold mode, there-
fore, there is no need to constantly control the throttle.
Drone control
The left lever controls the drone’s fl ight altitude (up – down).
The left lever controls rotation of the drone (left – right).
The right lever controls fl ight forward – backwards, left – right.
Drone landing
During fl ight, the user has two landing options.

Drone landingDrone landing
During fl ight, the user has two landing options.

EN
Manual landing:
Using the altitude control lever, lower the drone’s altitude. Hold the altitude control lever in an
extreme bottom position – the drone will land and turn off the motors.
Automatic landing:
Click the auto-landing button. The drone will automatically lower the fl ight altitude, and then land
and turn off the motors.
Headless mode
A standard drone control consists of moving in accordance with the design of the drone, that
is by pressing the control lever up, the drone will fl y in the direction pointed by its front side. In
the headless mode, control is based on the position of the drone in relation to the remote in the
moment of activation of the mode. This means that if we activate the headless mode when the
drone is turned sideways to us, moving the control lever up will make the drone move away from
us instead of fl ying sideways like in case of standard control. This mode facilitates control, as the
user does not have to worry about the position of the front side of the device.
Mode activation: During drone’s fl ight, press and hold the headless button.
Warning! Before activating the headless , calibrate the drone using the automatic calibra-
tion button. When controlling the drone in the Headless mode, the user should remain in
the place where mode was activated. Moving when the Headless mode is activated may
result in loss of control!
Drone fl ight speed change
The drone has 3 fl ight speeds:
– low (30% power)
– medium (60% power)
– high (100% power)
Together with the increase of the drone’s speed, its sensitivity to issued commands grows. Begin-
ner users should use the lowest speed.
The speed may be changed by pressing the Flight speed change button. By standard, after star-
ting up the drone is set to the lowest speed. After pressing the button, the user hears a sound
signal:
– a single signal – low speed is set;
– a double signal – medium speed is set;
– a triple signal – fast speed is set.
Stunt mode
The drone off ers a stunt mode, in which it can perform 360 degrees rotation in four directions
(forward/backwards/left/right)
To rotate the drone:
1. The drone must be at the altitude of at least 2 m.
2. Click the fl ight direction control lever (right lever).
3. Point the fl ight direction lever in the desired direction of a stunt.
