Altitude Hold Mode

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).

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.

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.

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.
