GPS Functionality of the 350 QX
Flight Guidelines and Warnings
To acquire a reliable GPS signal, it is important the 350 QX has a clear view of
the sky. Obstructions that can affect the aircraft’s ability to acquire an acceptable
signal include:
• Flying close to or around tall/big buildings
• Flying under dense vegetation
• Flying indoors or under a structure
If you lose or cannot acquire a GPS lock and home position, the aircraft will not
have Stick Relativity, SAFE Circle, Position Hold or Return Home functions avail-
able.
It is not possible to use
Smart Mode
without having GPS enabled. If the 350 QX
is initialized without GPS enabled, it will default to
Stability Mode.
The aircraft
will still be capable of altitude hold.
If you do not have a GPS signal, try maneuvering the 350 QX by steering with
forward elevator and rudder only.
CAUTION:
Do not attempt to fl y the 350 QX with GPS enabled while
indoors or in a location where the GPS signal is known to be poor, as
loss of signal could result in a crash.
GPS Functions
(
see the binding section for turning GPS functions ON and OFF
)
With
GPS ON
• If the 350 QX took off with GPS lock and a home position set, when Return
Home mode is activated the quadcopter will fl y back to the start position
(maintaining altitude along the way), then reduce altitude to land.
• If the 350 QX should lose GPS when Return Home mode is activated, it will
land quickly using the barometric pressure sensor to maintain the descent
rate.
• If the 350 QX took off without GPS lock, but acquires a GPS signal in fl ight, it
will land slowly using GPS to hold its position and barometric pressure sen-
sor to maintain the descent rate when Return Home mode is activated.
• If the 350 QX loses GPS during landing in Return Home mode, it will in-
crease the rate of descent and land quickly to avoid drift.
• If the 350 QX deviates too far from its intended GPS path when in Return
Home mode, it will descend using the barometric pressure sensor to main-
tain the descent rate. This could happen if the fl ight control system loses its
orientation because of aggressive fl ight in 3 axis mode.
• Once the 350 QX has landed in Return Home mode it will disarm the motors
With
GPS OFF
• If Return Home mode is activated, the 350 QX will level off and land quickly
using the barometric pressure sensor to maintain the descent rate.
• Once the 350 QX has landed in Return Home mode it will disarm the motors.
GPS Failure
Upon GPS failure, the 350 QX will respond according to the following conditions:
Smart Mode:
(rapid Green fl ashing LED)
If the 350 QX is in this mode and the GPS fails, the quad will default to
Stability Mode.
The aircraft will still use the pressure sensor to maintain
altitude and control rate of descent. If GPS is re-acquired, after 5-10
seconds of reliable GPS signal the
Smart Mode
functions are returned to
normal
Stability Mode:
(long Blue, two short Green fl ashing LED)
If the 350 QX is in this mode and the GPS fails, it will not switch to
Smart
Mode
and will not enter GPS hold, but will otherwise function normally. If
GPS is reacquired, after 5-10 seconds of reliable GPS signal the
Stability
Mode
functions are returned to normal
Agility Mode:
(long Red, two short Green fl ashing LED)
If the 350 QX is in this mode and the GPS fails, it will not affect fl ight perfor-
mance, but it will not be able to switch into
Smart Mode.
It will still be able
to switch into
Stability Mode
with the limitations described above.
Loss of Transmitter Signal
If the transmitter signal is lost for any reason, the 350 QX will respond according
to the following conditions:
• If the motors are not turning, the 350 QX will disarm.
• If the motors are turning but the 350 QX is not fl ying, it will turn off the mo-
tors and disarm.
• If the 350 QX is fl ying and has a good GPS lock with a home position set,
it will activate the Return Home function upon the loss of the transmitter
signal.
• If the compass is not connected or faulty, or if there is no GPS lock, the 350
QX will descend slowly upon the loss of the transmitter signal.
• If the pressure sensor is not working, the 350 QX will reduce power to initi-
ate a controlled descent upon the loss of the transmitter signal.
• Always keep aircraft in sight and under control.
• Always keep people and pets at least 35 feet (10 meters) away when the
battery is connected.
• Keep children out of the vicinity of this product at all times.
• Always use fully charged batteries.
• Always keep transmitter powered on while aircraft is powered.
• Always remove batteries before disassembly.
• Always keep moving parts clean.
• Always keep parts dry.
• Always let parts cool after use before touching.
• Always remove batteries after use.
• Always have a fi rst aid kit with you.
• Always have an appropriate fi re extinguisher with you.
• Never operate aircraft with damaged wiring.
• Never touch moving parts.
The Blade 350 QX has many more features than other Blade quadcopters.
Please take the time to read this manual and understand the functions this
aircraft contains before fl ying.
