4.2.2 FLIGHT MODE
4.2.2.1 Introduction spreadsheet
GPS mode: The most commonly used mode. In this mode, the compass
and GPS will be activated to make the drone recognize the current
location precisely, it ensures you to fly the drone in good gesture and
easily hover anytime. Different from the ATTI mode that is suitable for
senior pilot, GPS mode is suitable for new pilot and aerial filming.
However, weekness consists that the GPS & compass module is quite
sensitive against magnetic interference.Make sure to fly in a place
without strong magnetic interference and good GPS signal.

ATTI mode: Under ATTI mode, the flight operation doesn't rely on GPS
module. The drone can maintain the height, but not able to lock the
position automatically. This mode is good for senior pilot and necessory
for every drone. Due to GPS senstivity and poor GPS signal, it's not
advised to fly the Splash Drone indoor, or around the crowd and strong
magnetic environment.
(Important notice: when your drone is out of control suddenly in GPS
mode, the best way to get it back is switching to ATTI mode to bring it
back manually).

4.2.3 READING OSD DATA ON CONTROLLER SCREEN
4.2.3.1 Find out and recognize the OSD data
Circle flight: Fly the drone over the target object, switch SWC to SWC2
(Circle Flight) to activate Circle Flight mode. The drone will take this point
as the center of circling. The target object will be recognized as the
default nose/camera direction. Pull the AILERON joystick down to
enlarge the circle diameter, push up to reduce the circle. Slightly turn
AILERON joystick to left, the drone will make a counter-clockwise circle
flight. Keep turning the joystick to right, the drone will slow down the
counter-clockwise circle fight until implementing clockwise circle flight.
Keep turning more, the circlie flight speed will be faster. The circling
speed is proportional to the AILERON joystick movement. Use the
THROTTLE joystick to increase or decrease the flight altitude, use the YAW
joystick to turn the nose/camera direction.
Return-Home mode will be active once flipping the SWB to SWB2
(Return-Home) position. YAW (nose) direction is controllable in
Return-Home mode. When the drone returns to the TOP point of take-off
location, both YAW and AILERON joystick are controllable for a better
landing-off location, Throttle is unavailable in Return-Home mode.
Note: To prevent unexpected accidents, please DON’T take-off under Circle Flight
mode. Find out the drone NOSE direction before quitting Circle Flight mode.
Circle Flight
Return-Home
