## General Safety Precautions and Warnings

• Always keep a sate distance in all directions around your model to 

### avoid collisions or injury. This model is controlled by a radio signal subject to interference from many sources outside your control. Interference can caJse momentary loss of control. • Always operate your model in open spaces away from full

- size vehicles, traffic

and people

. • Always carefully follow the directions and 

### warnings for this and 

### any optional

support equipment (chargers, rechargeable battery packs, etc.). • Always keep all chemicals, small parts and anything electrical out of the reach

of children. • Always avoid water exposure to all equipment not specifically designed and

protected for this purpose. Moi sture causes damage to electronics

. • Never place any portion of the model in your mouth as it could cause serious

injury or even death. • Never operate your model with low transmitter batteries. • Always keep aircraft in 

### sight and under control. • Always move the throttle fully down at rotor strike. • 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
. • Never operate aircraft with damaged wiring

. • Never touch moving parts

## GPS Functi onality To acquire a refiable GPS signal, it is important the 350 QX3 has a clear view of the sky. Obstructioos that can affect the arcraft's ability to acqui:e an acceptable signal indude:

• Flying close to or around taiVbig buildings • Flying under dense vegetatioo • F lying indoors or under a s tructure If you cannot acqu r e a GPS lock a t startup, the motors cannot be started in either S

mart Mode o r AP Mode. You will have 

### to re-bind the quadcq>ter with the GPS functions turned ctfto allow you to start the m!Xors for flight (see the Binding sectiorf].lt is not possible to use Smart Mod e without having GPS enabled

. If the 350 QX3 is initialized with GPS disabled , it will default to AP Mode without position hold , bu t will still b e capabl e 

### of anitude hold

. If you lose the GPS signal while flying, the aircraft will not have Stick Relativity, the SAFE Circle'" feature , Position Hold or Return Home funct ions available. We recommend maneuverin g the 350 QX 3 by steerilg with forward eleva1Dr and rudder only if GPS signal is lost



## A CAUTJON: Do not attempt 1D 

### fly the 350 QX3 with GPS enabled while 

### £ll indoors or in a locatioo where the GPS signal is known 1D be poor, as loss of signal could result in a crash

. 

### GPS 

### Fun ctions (see the Bind ing section fa fuming GPS functions ON and OFF) WithGPSO N

• If the 350 QX3 took off with GPS lock and a home pooit ion set,when Return

Hom e mode is activated the quadcopter will fly back to the start position (maintaining altitude a loo g th eway) , then reduce anitude to land. • If the 350 QX31ooes GPS lock while flying in Smart, AP or R eturn Hom e mode, the LED will flash green, purple or red , depending on which flight mode you are currently using. The 350 QX3 will defaun to a stable flight mode with similar contra response to AP Mode without the availability d positioo hold. • If the 350 QX3 deviates too far from its intended GPS path when in Return

Hom e mode , itwill descend using the barometric pressure sensor to maintain the descent rate

. • Once the 350 QX3 has landed In Return Horne mode, it will stop the motors. WithGPSO FF • The LED will show solid white. • The fli ght mode available will be similar in contra response to AP Mode

withoutthe avail ability of position hold

. • Mitude hold will function norma lly

. 

### L oss of GPS Signa l If the 350 QX31ooes GPS signal in**fligh~** it will respond according to the followin g conditions:

Smart Mode: (Green flashing LED)

If the 350 QX31ooes GPS signal in flight while in Smart Mode the LED will flash green

If the 350 QX31ooes GPS signal In flight while in AP Mod e the LED will flash purple. The quadcopter will

### niX function. If GPS signal is reacquired after receiving 5-10 seconds of reli able signal , AP Mode fun ctions retu rn. 

### L oss of Transmitter Signal If the transmitter signal is lost for any reason , the 350 OX3 will respond according to the followilg oonditi oos:

• If the m!Xors are stq>ped ,the 350 OX3 will disarm. • If the m!Xors are turning but the 350 QX3 is not flying, it will stop the motors

and disarm. • If the 350 QX3 is flying and has a good GPS lock with a home position set, it

will activate the Return Home functi on (rapid red f lashing LED) upon the loss of the transm itter signal. • If the compass is faulty, not connected or ifthere is no GPS lock,

the 350 QX3 descends slowly wh en the transmitter signal is lost • If the pr essure sensor is niX working, the 350 QX3 r e duces power to oontrol the decent when the transmitter signal is lost.

## Flight Guidelines and Warnings

• Always inspect the model before flight • Always keep aircraft in sight and under control. • Always keep people and pets at least 35 feet (1 0 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 m while aircraft is powered. 

## Preparing the 350 QX3 For Flight

place the quad on a flat, level surface. 2.While holding the bind switch on the transmitter,

cycle the top left switch 4 times as shown at the left

. 3.The 350 QX3 wUI emit a series of slow tones

followed by a series of rapid tt11es, indicating the calibration has started. 4.Do not move the 350 QX3 while it performs the

accelerometer calibration procedure

. 5.When the procedure has completed ,the 350 QX3 will

emit a "happy" tone and the LED will display green indicating the calibration was successful. If it emits a "sad" tone and the LED displays solid red , repeat the ca libration procedure. 

### Press ure Senso r Ca libration The pressure sensor is calibrated at the factory on the 350 QX3. Recafibration should only be necessary if you reploce the sensor. 1.Piace the 350 QX3 in a cold area. Allow it to remain

in the cold for 30 minutes or more. 2.Bring the 350 QX3 out of the cold and into awarm

area. The greater the difference in temperature between the cold and warm areas, the more accurate the calibratKm will be. 3.Ensure your transmitter is off and then connect a

flight battery to the 350 QX3Power the 350 QX3 ON and le t it initialize

.The status LED will remain off. 4. Hold the 350 QX3 upside down until the status LED

flashes blue , ildicating it has entered bind mode. 5. Set the quadcq>ter back upright 6.Bind your transmitter 

### to the 350QX3 with the rudder

stick fully to the right The LED will blink red and blue rapidly. Leave the aircraft and transmitter powered on and allow the aircraft to warm up for 10 minutes. Do not move the aircraft during this time. ?.After 10 minutes the motors on the aircraft will beep

to indicate the calibration is complete. Power off the aircraft and then your transmitter. If the 350 QX3 displays the failed calibration code, power off the aircraft
