TIPS
Always keep the monocular camera lens clean for a clear view.
Do not use other 40KHz ultrasonic devices nearby when the
Starpoint
TM
Positioning System is activated.
Landing and Motor Shut-down
The aircraft can be landed manually, automatically, or passively.
IMPORTANT
The aircraft must be landed gently on a at surface to avoid damage.
z Manual Landing
You can manually land the aircraft whenever and wherever you want by
maneuvering the command sticks on the remote controller.
¾ To land the aircraft manually
1. Maneuver the aircraft to the desired position for landing.
2. Release the command sticks when the aircraft reaches the target
position to let it hover.
3. Push the Descent stick steadily and gently to land the aircraft.
¾ To shut down the motors
When the aircraft has properly landed, use one of the methods below to
shut down the motors:
Descent Stick: Both Command Sticks:
Push to the end
and hold for 2s
Hold toe-in or toe-out for 2s
WARNING
The toe-in action will always shut down the motors even if the
aircraft is in midair. Please be extra cautious and use this feature
only in an emergency, e.g., when the aircraft gets out of control.
z Starpoint
TM
Positioning System
The Starpoint
TM
Positioning
System installed on the X-Star/X-
Star Premium functions through
a monocular camera and two
ultrasonic sensors on the bottom
of the aircraft. The sensors help
to identify the current height of the
aircraft through ultrasound, and the
camera obtains location information
through image analysis. With the
help of the Starpoint
TM
Positioning
System, the aircraft can hover in place more precisely when ying indoors or
in other environments where the GPS signal is unavailable.
NOTE
The Starpoint
TM
Positioning System is activated by default when
the aircraft is turned on.
The Starpoint
TM
Positioning System works both in GPS and ATTI
modes and is only valid when the aircraft is between 30cm and
300cm above the surface.
IMPORTANT
The performance of the Starpoint
TM
Positioning System is affected
by the brightness and texture of the surface over which the aircraft
is ying. The ultrasonic sensors may not function accurately above
sound-absorbing materials. Please try to avoid the following situations:
Flying over a monochrome surface (e.g. pure black, white, or red)
or a highly reective surface (e.g. water, transparent surfaces).
Flying over extremely dark or bright surfaces, or in an area where
the lighting changes frequently.
Flying over surfaces with unclear patterns or texture, or highly
repeating patterns or texture (e.g. tiles with the same design).
Flying over surfaces (e.g. thick carpet) that can absorb or deect
sound waves.
Flying at a high speed: over 8m/s at a 2-meter height, or over 4m/s
at a 1-meter height.
Flying over moving surfaces or objects.
