GPS Failsafe
The X8 requires GPS lock before takeoff. Enclosed areas, physical
obstructions, and lack of available satellites can affect GPS strength. If
the X8 loses GPS lock in flight, it will trigger a GPS failsafe, indicated by
a blinking blue and yellow LED with a high-high-high-low tone, and
automatically switch to manual control (standard - altitude hold mode).
Always be prepared to regain manual control at any time while flying and
choose an unobstructed flying area to improve GPS signal strength. When
flying a mission, we recommended changing the GPS failsafe behavior to
land. (Visit 3DR.com/X8/info for more information about configuring the
GPS failsafe.)
Altitude Failsafe
The X8 has a 100 m (328 ft) altitude geofence enabled by default. If the
geofence is breached, the X8 will automatically RTL.

Range Failsafe
The X8 has a 300 m (984 ft) horizontal geofence enabled by
default. If the X8 travels farther than 300 m from the launch point, it
will automatically return to the launch point and land. If you plan to
fly a mission that exceeds this range, you will need to disable the
horizontal geofence. (Visit 3DR.com/X8/info for instructions.) The
range failsafe will be disabled in the event of a GPS failsafe.
