Drone Indication Lights
The Splash Drone 3 utilizes a brand new flight control system, incorporating 3 of the best
flight modes.
This uses the GPS modules to achieve accurate and stabilized hovering,
intelligent flight, intelligent return and other intelligent flight mode functions.
Maximum flight speed of 10m/s, maximum ascend speed of 4m/s, and
maximum descend speed of 3m/s.
Specially designed for smooth aerial filming. The turning function of left
joystick is disabled, and is mixed into the right joystick, thereby freeing up
your left hand, with the other hand to used control the drone’s direction, and
flight path.
This mode does not use the GPS positioning function, but still maintains
attitude stabilization.
Note: With a good GPS signal, intelligent return can be achieved. A maximum
flight attitude angle of 25 degrees, a maximum flight speed of 16m/s, a
maximum ascent rate of 4m/s, and the maximum descend rate of 3m/s.
Please Note: In ATTI mode, and the drone’s speed is faster. When flying in a calm
environment, the pilot should allow a minimum of 30 meters for braking distance to
ensure flight safety.
Select the preferred flight mode of the drone using the remote mode switch on the
controller.

Return Home
Splash Drone 3 has an auto return home function. If the GPS successfully recorded the return
point before takeoff, and, if the remote controller and the aircraft loose communication with
each other, the drone will automatically return to the landing point, and land. Splash Drone 3
provides two auto return home modes, they are: one key return and failsafe return.

During take off, or during the flight process, the GPS signal
should be greater than 6 satellites, the drone will save the
current position as the return point. When taking off in GPS
mode, it is recommended that the GPS satellite count is
greater than 9 satellites.
Description
Remote Control
Turn the Return Home switch to Return Home position, the
drone will activate its return home mode. In this mode, the
drone will automatically return to the home point.

©2017 SwellPro All Rights Reserved 15
If the drone goes out of effective distance, the Return Home function will be activated
automatically. When the remote control communication is recovered, the control of the
drone can be resumed after a single switching of the flight mode Switch, regardless of the
current mode is under ATTI or GPS.
Propeller Installation
Failsafe Return Home
Note: During the return process, only the (right) steering stick can be controlled. When
the drone returns to the point of departure, and commences its descent, the left joystick
will only control the direction (Heading) of the drone, the right joystick controls the
forward/back and sideways functions, in order to select and land at the chosen landing
point. If you need to take control of the drone, you need to switch the Return Home
switch to Normal position.
If the GPS signal is poor (Value is less than 5) or GPS doesn’t work, the Return Home
function will not be available.
Vertical height > 20metres, horizontal distance > 15metres,
drone will maintain same altitude and return to its home
point.
Vertical height < 20metres, horizontal distance > 15metres,
drone will ascend up to 20metres, and return to its home
point.
Vertical height < 10metres, horizontal distance < 15metres,
the drone will maintain its altitude, and return to it’s home
point.

When installing or removing the propellers, please place your free hand under the
motor, so as to provide support and a back force when pushing down to lock or unlock
the propeller. Failure to provide this support could result in the bending or breaking of
the landing gear.
Prior to each flight, please check that the propellers are correctly installed and securely
fastened.
If a propeller becomes damaged, or broken, please replace it, they can be purchased
separately.
Please do not get too close to the rotating propellers and motors, to avoid cuts or injury.

3. Indication lights: One LED on indicates a charge level of 25% , two LEDs on indicate a
charge level of 50%, three LEDs on indicate a charge level of 75%, four LEDs indicate that the
battery is fully charged.
1. In low temperature environments (-10C degrees to 5C degrees) , the flight time will be
reduced. Before use, please fully charge the battery, and keep it warm.
2. In low temperature environments, it is recommended to stop flying if and when the low
battery alarm is on.
3. In low temperature environments, it is recommended to preheat the battery before flying.
Low temperature precautions
When inserting the battery, please take note
and observe the following precautions:
-Please ensure the battery is “lying on it’s side”
with the cables exiting the battery towards the
rear of the drone,
-Please observe the label on the battery.
-Please observe the instructions and the arrow
on the label.
Battery Installation
Before charging, please ensure that you are using the correct battery type.
If, during the charging process, the 4 indicator lights flash at the same time, this
indicates a charger or battery failure, please stop charging.
There are two low battery alarms, which can be set by adjusting the parameters in the
setup. The first level is at 14.8V, the red LED on the drone will flash three times, the
second level is at 14.4V, at this level, the red LED will flash continuously, while the drone
will commence its auto landing sequence.
Please Note: There are no low battery alarms on the controller.
While operating the drone, please monitor the battery voltage level, and keep the
voltage level in mind, when the level has dropped to 14.8V, please prepare to return the
drone to a safe landing place.
It is dangerous to continue flying the drone once with insufficient battery power. This
could result in damage to the battery.
