Flying
5
Select an open area for flying, away from people
and buildings, and remember to bring the Flight
Checklist and a fully charged battery.
Connect the battery to the underside of the
copter using the velcro straps. Ensure the
battery is secured tightly before takeoff.
If you plan to use loiter, autonomous, or
return-to-launch modes during your flight,
check the APM’s LED. Wait to see the solid
blue LED, indicating that GPS lock has been
achieved, before takeoff. If you plan to fly
only in stabilize or altitude hold modes, you
may proceed without GPS lock.
Determine the boundaries of your flying area
before takeoff, and select a level, unobstructed
space as a launch point. Place the copter at the
launch point with the blue arms facing away
from you.
1 Before flying, turn on your RC transmitter. Make
sure the left stick is set fully down and you have
selected a flight mode. Check your copter to
verify that the propellers are tight, antennas are
vertical, and all components are secure.
