GPS Functionality

To acquire a reliable GPS signal, it is important the 350 QX3 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 cannot acquire a GPS lock at startup, the motors cannot be started in either

Smart Mode or AP Mode. You will have to re-bind the quadcopter with the GPS

functions turned off to allow you to start the motors for ﬂ ight (see the Binding

section). It is not possible to use Smart Mode without having GPS enabled. If the

350 QX3 is initialized with GPS disabled, it will default to AP Mode without position

hold, but will still be capable of altitude hold.

If you lose the GPS signal while ﬂ ying, the aircraft will not have Stick Relativity, the

SAFE Circle

™

feature, Position Hold or Return Home functions available. We recom-

mend maneuvering the 350 QX3 by steering with forward elevator and rudder only

if GPS signal is lost.

CAUTION: Do not attempt to ﬂ y the 350 QX3 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 QX3 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 QX3 loses GPS lock while ﬂ ying in Smart, AP or Return Home

mode, the LED will ﬂ ash green, purple or red, depending on which ﬂ ight mode

you are currently using. The 350 QX3 will default to a stable ﬂ ight mode with

similar control response to AP Mode without the availability of position hold.

• If the 350 QX3 deviates too far from its intended GPS path when in Return

Home mode, it will descend using the barometric pressure sensor to maintain

the descent rate.

• Once the 350 QX3 has landed in Return Home mode, it will stop the motors.

With GPS OFF

• The LED will show solid white.

• The ﬂ ight mode available will be similar in control response to AP Mode

without the availability of position hold.

• Altitude hold will function normally.

Loss of GPS Signal

If the 350 QX3 loses GPS signal in ﬂ ight, it will respond according to the

following conditions:

Smart Mode: (Green ﬂ ashing LED)

If the 350 QX3 loses GPS signal in ﬂ ight while in Smart Mode the LED will

ﬂ ash green. The stick relativity feature of Smart Mode will not function. The

350 QX3 will follow the control stick input direction relative to the position and

orientation of the aircraft rather than the position of the pilot, similar to the

control response in AP Mode. Return home will not function. The aircraft will

still use the pressure sensor to maintain altitude and control rate of descent.

If GPS signal is reacquired, after receiving 5–10 seconds of reliable GPS

signal, the Smart Mode functions return.

AP Mode: (Purple ﬂ ashing LED)

If the 350 QX3 loses GPS signal in ﬂ ight while in AP Mode the LED will ﬂ ash

purple. The quadcopter will not enter GPS position hold when the right stick is

returned to center. Return home will not function. If GPS signal is reacquired

after receiving 5-10 seconds of reliable signal, AP Mode functions return.

Loss of Transmitter Signal

If the transmitter signal is lost for any reason, the 350 QX3 will respond

according to the following conditions:

• If the motors are stopped, the 350 QX3 will disarm.

• If the motors are turning but the 350 QX3 is not ﬂ ying, it will stop the motors

and disarm.

• If the 350 QX3 is ﬂ ying and has a good GPS lock with a home position set, it

will activate the Return Home function (rapid red ﬂ ashing LED) upon the loss

of the transmitter signal.

• If the compass is faulty, not connected or if there is no GPS lock,

the 350 QX3 descends slowly when the transmitter signal is lost.

• If the pressure sensor is not working, the 350 QX3 reduces power to

control the decent when the transmitter signal is lost.
