P
N
E
P Mode (Professional): professional ight mode
In this mode, sonar is used instead of GPS and the visual positioning system. The aircraft is
essentially on full manual control.
N Mode (Normal): Normal ight mode
In this mode, the aircraft uses GPS or the visual positioning system, depending on their
signal strength. If GPS is unavailable the visual positioning system and sonar are used to
ensure accurate hovering of the aircraft, including indoors. When neither GPS signals nor
the visual positioning system satises the condition for proper and safe ight, the system
will automatically switch to Professional Mode. In this case, only sonar is provided.
E Mode (Easy Control): Super-easy ight mode
：In this mode, GPS will be enabled and it is not necessary to focus on the ight orientation
of the aircraft. The forward and backward ight direction of the aircraft is relative to the
operator. Pushing the right joystick forward will move the aircraft away from the operator,

regardless of aircraft’s true orientation. There also will be a 10m-radius safe zone located
around the operator. The aircraft cannot enter the safe zone and the control of the aircraft
within the safe zone is disabled.

Automatic take-off
Automatic landing
Unlock the aircraft and ensure ight conditions for either via GPS signals or the visual
positioning system meet minimum requirements. Long press the automatic take-off button
on the remote controller until it vibrates. The aircraft ascends to a height of 1.3m above the
ground at a set speed and then automatically hovers in the air.
Long press the automatic landing button until it vibrates. The aircraft starts to descend at a
set-speed from the current position, subject to horizontal control during descending.
Smart return-to-home
The smart return-to-home mode may be applied only when there is ample GPS signal. In
this mode, the aircraft returns to the return point from the current position (when switched
to the return-to-home mode).

regardless of aircraft’s true orientation. There also will be a 10m-radius safe zone located
around the operator. The aircraft cannot enter the safe zone and the control of the aircraft
within the safe zone is disabled.

Smart return-to-home behavior
The return-to-home behavior depends on the location of the aircraft when it is switched to
return-to-home mode.
1.When the aircraft is located within 10m horizontally from the return-to-home point, it deploys
the landing gear and automatically lands on the spot.
2.If the aircraft ies higher than the return altitude (default value: 20m) beyond 10m, it rst
makes a turn to face its head towards the operator, ies to the position above the return point,
and then deploys the landing gear for vertical landing. The location of nal landing can be
controlled by the joystick.

There are three kinds of return points: user location, aircraft starting point and map selection
point. The take-off point of the aircraft will be selected as the return point for default when
changed in the Vision+ app. Each time after power cycling the aircraft, the return point will be
automatically reset to the take-off point. Please select a proper return point each time after
power cycling.
Return point
altitude: 20m
If the aircraft ies lower than the return altitude beyond10m, it rst vertically climbs to the
return altitude, then turns the head to the operator and returns to the point above the return
point. Then, the aircraft turns the tail towards the operator, deploys the landing gear and
vertically lands on the ground. During the nal descent, the location of nal landing can be
controlled by the joystick of the remote controller.

Categorization of smart return-to-home
12

Smart return-to-home can be realized in three patterns: lost control return, one-click return
and low power return
1.Lost control return
In the case of loss of signal, the aircraft rst hovers in the air and then triggers lost control
return in 10 seconds. After gaining signal of the remote controller again, the aircraft switches
to the mode used prior to the loss of signal and continues to y.
2.One-click return
Long press the return-to-home button on the standard remote controller to trigger one-click
return. Short press the button to cancel return-to-home. The aircraft can operate at different
horizontal positions via the joystick of the remote controller during the descending process.
3.Low-battery return
When battery level of the aircraft drops to a predetermined level, Vision+ will pop up a
message for the user to decide whether to trigger low-battery return. Click “Yes” to return
the aircraft. Return can be terminated by pressing the automatic Return-to-home key on the
standard remote controller. During the descending process, the user may manipulate the
joystick to change the position of the aircraft in horizontal direction so that it can land in a
safe zone.
Note: The aircraft may have obstacles in its path during return-to-home. The user needs to
detect such obstacles via visual observation or image transmission, and avoid these obsta-
cles by means of ending the return-to-home process or adjusting ight height of the aircraft.

Each arm of PowerEgg has a head indicator (head lamp) and an aircraft status indicator (tail
lamp).The following gure indicates the specic locations of the indicators.
10.Cell damage detection: a warning for battery damage will be sent out if cell damage or
signicant cell imbalance is detected.
11.Records of use exceptions of the battery: the app can provide the records of the last 31
times of use exceptions of the battery, including battery short-circuit, excessive discharging
current, etc.
12. Sleep protection: the battery will enter into sleep if it is not connected to any electrical
equipment 20 minutes after it is turned on.
13. Communication: the aircraft can acquire real-time information of the battery through the
communication interface on the battery, including voltage, battery level and current.
Aircraft Status Indicator
Orbit mode
While ying with GPS, the aircraft ies at a height of 10m above the ground. Specify the
center of a circle via Vision+ and manipulate the aircraft to y to any position 10m beyond
the center of the circle. Set the orientation via Vision+ and start the circling mode. During
circling, the head of the aircraft will always point at the center of the circle.
Sele mode
While ying with GPS, the user only needs to press the Sele button on the gesture-based
remote controller when the aircraft is ying. The head of the aircraft will automatically aim at
the user.
Waypoint mode
While ying with GPS, the user may set a ight waypoint via Vision+ and the aircraft will y on
the set waypoint trajectory.
Follow-me mode
While ying with GPS, the aircraft can follow the standard or gesture-based remote controller
and move correspondingly at a certain distance, with the ight height adjusted by the remote
controller.

to lower the battery level to 65% for the protection of the battery. The self-discharging process
may last for about two days with no LED indication. The battery may heat up slightly, which is
normal.
4.Balance charging protection: cell voltage of the battery can be automatically balanced to pro-
tect the battery.
5.Overcharging protection: Charging will be automatically stopped when the battery is full.
6.Charging temperature protection: the battery will be damaged if it is charged at a tempera-
ture lower than 0℃or higher than 40℃. This function is to ensure the battery will not be charged
at such temperatures.
7.Overcurrent protection during charging: heavy current charging can severely damage the
battery. Charging will be stopped if the current exceeds 8A.
8.Over-discharging protection: over-discharging can severely damage the battery. The battery
output will be cut off if it is discharged to 12V.
9.Short-circuit protection: the output will be cut off to protect the battery if short-circuit is
detected.
