Self-checking of the aircraft fails after it is
powered up (the buzzer beeps all the time)
(1) Check the mainboard power switch of the aircraft
to make sure it is in the ON (powered up) state
(2) Check the battery of the aircraft to see if there is
any poor contact
Speeds of four motors are obviously
inconsistent with each other after startup
(some run fast, while some run slowly)
(1) Make sure the aircraft is placed on a at ground
before take-off
(2) Use the pitch and roll joysticks of the remote
control to optimize take-off process.
The aircraft cannot be started after
successful self-checking
Check the manual/auto switches of the remote control
and the ground station to make sure they are in the
manual state
Normal take-off fails when the throttle lever
is pushed forward after the aircraft is started
(1) Check the four propellers of the aircraft to see
if they are installed onto the motors properly as
required
(2) Check the power batteries of the aircraft to make
sure the battery level is high enough.
Protection Mechanism
During flying in the manual mode, when it is beyond the operating range, the aircraft will enter the
protection mode, and automatically y back to the take-off position and land.
During ying in the manual/auto mode, when the remote control or the ground station is powered off, the
aircraft will enter the protection mode, and automatically y back to the take-off position and land.
In case of Level 2 alarm for low battery, the aircraft will enter the protection mode; at this moment, the
aircraft will vertically descend to the ground (in case of an emergency, in the auto fly mode, you can
switch to the manual mode to control landing manually; in the manual y mode, switch to the auto mode
and then to the manual mode to realize manual control of landing).
