Emergency Stop: When the drone in emergency situation
and going to hit people or an obstacle etc., press the
Take Off / Landing / Emergency Stop Button
immediately and hold it for more than 1s. 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 lever up (down) to fly the drone at a
certain altitude and then release the lever. The lever will
go back to the center position (Altitude Hold Center)
as Picture 10 shown. And the drone will keep flying at
current altitude. Repeat above steps if you want to
change the drone altitude (Default mode).
