Take Off / Landing / Emergency Stop Button
Picture 16

1. Method 1 (Landing): When flying, push the Left Stick all the way down to the lowest position(Picture 13) and hold it till the motors stop and the drone will land on the ground slowly.
2. Method 2 (One Button Landing): When flying, press the Take Off / Landing / Emergency Stop Button once shortly(picture 16), and the drone will land on the ground automatically. (When using this function, you can not touch the left stick, if not, then the function will fail)

▲Emergency Stop: When the drone in emergency situation and going to hit the walking people or obstacle etc., press the Take Off / Landing / Emergency Stop Button immediately and hold it for more than 1s( picture 16). The propellers will stop immediately.

Tip: Do not use the emergency stop function unless in emergency situation. The drone will fall down suddenly after all propellers stop.

Altitude Hold Mode

Altitude hold mode indicates that the drone maintains a consistent altitude while allowing roll, pitch, and yaw to be controlled normally. It makes easier to control

the drone for beginner and more stable

for aerial photography.

Push the Left Stick up (down) to fly the drone up (down) at certain altitude and then release the Stick. The Stick will back to the center position (Altitude Hold Center) as Picture 17 shown. And the drone will keep flying at current altitude. Repeat above steps if you want to change the drone altitude (Default mode).

Note: The Altitude Holding Mode can not be used when the blades are accidentally deformed or damaged.

High / Medium/Low Speed Mode Switch

Press down this button, then it will sound “di”, it means low speed mode “L”; when it sounds “di.di”, means medium speed “M”; and sounds “di.di.di” means

high speed mode "H".

Low Speed Mode(Mode 1)

1. Low Speed Mode is suitable for beginner.

Medium speed Mode(Mode 2)

1. Medium Speed Mode is suitable for skillful pilots to play in the gentle breeze.

High Speed Mode(Mode 3)

1. High Speed Mode is suitable for expert to experience aerial stunt in outdoor.

Heading Hold Mode

Drones generally have a front and rear indicated by LED lights or colored propellers. By default, the users are required to tell the front and the rear of the drone when flying. Under heading hold mode, the users can operate the drone without worrying about the orientation (left is left and right is right all the time, regardless of where your drone is pointing at). Heading Hold Mode is designed for beginners and the users who fly the drone in daylight or at a far distance or difficult to identify the drone orientation.

The default setting is NOT Heading hold Mode.

You are allowed to activate the heading hold mode function before taking off or in flight. Fly under heading hold mode, you're required to ensure the drone front direction aligned with your front direction, DO NOT change your direction of your transmitter and keep it fly in front of you all the time.(See below picture)

WARNING: DO NOT USE HEADING HOLD MODE BEFORE YOU ARE SURE THAT THE DRONE'S FRONT IS YOUR FRONT. OTHERWISE, IT MIGHT BE OUT OF CONTROL OR FLY AWAY.

* Press down Heading hold mode button, the drone's left and right LED will start flashing alternately, it shows the drone enters Heading hold mode, press the button again, then the LED gets solid and the drone ESC from heading hold mode.
