Intelligent Attitude Mode :
● Usually, intelligent attitude mode is activated when the Quad-copter flies beyond 
visual range.
● When the intelligent attitude mode is activated by CH.6, it uses the vehicle’s 
position relative to home instead of the vehicle’s initial heading when it was 
armed. This means no matter where the vehicle is, pulling the pitch back will 
cause it to return towards home regardless of the vehicle’s actual heading.
Intelligent attitude mode: 
Controls are applied based 
on the Quad-copter’s GPS 
position relative to home.
The orientation is not 
updated when the vehicle 
is within 10m of home.
When the pilot fly the 
Quad-copter to the right, 
wherever the Quad-copter 
nose points, the Quad-
copter will fly to the right 
of the launch point; when 
the pilot fly the Quad-
copter to forward, the 
Quad-copter will fly away 
from the launch point.
Fail Safe:
Low Battery Fail Safe
● When the battery voltage reaches to failsafe voltage setting, all 4 arm LEDs will 
blink to warn the pilot, and the Quad-copter will activate RTL mode automatically. 
● Note: The Quad-copter will activate RTL mode automatically; but the voltage 
is possibly too low to finish landing. Usually pilot has 1 minute or less to finish 
landing.
