Low-Voltage Alert
Low-Voltage Alert is to indicate that the battery cannot provide enough power for the aircraft, in order to warn
you to land the aircraft ASAP. There are both first level and second level protections. It is not for fun, you should
land your aircraft ASAP to prevent your aircraft from crashing or other harmful consequences!!!
In ATTI. Mode & GPS ATTI. Mode.
 The first level protection has LED warning.
 During second level protection the aircraft will land automatically with LED warning. Meanwhile the center
point of throttle stick will move up slowly to 90% of endpoint, you should land ASAP to prevent your aircraft
from crashing! When the center point is at 90% of endpoint, aircraft will still ascend slowly if you continue to
pull the throttle stick, and the control of Pitch, Roll and Yaw are the same as before.
