The Battery Charger (EFLC3010) included with your quadcopter has been
designed to safely charge the Li-Po battery.
CAUTION: All instructions and warnings must be followed exactly.
Mishandling of Li-Po batteries can result in a fire, personal injury and/or
property damage.
• By handling, charging or using the included Li-Po battery, you assume all risks
associated with lithium batteries.
• If at any time the battery begins to balloon or swell, discontinue use imme-
diately. If charging or discharging, discontinue and disconnect. Continuing to
use, charge or discharge a battery that is ballooning or swelling can result in
fire.
• Always store the battery at room temperature in a dry area for best results.
• Always transport or temporarily store the battery in a temperature range of
40–120º F (5–49° C). Do not store battery or model in a car or direct sunlight.
If stored in a hot car, the battery can be damaged or even catch fire.
• Always charge batteries away from flammable materials.
• Always inspect the battery before charging
• Always disconnect the battery after charging, and let the charger cool between
charges.
• Always constantly monitor the temperature of the battery pack while charging.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED TO CHARGE LI-PO BATTER-
IES. Failure to charge the battery with a compatible charger may cause a fire
resulting in personal injury and/or property damage.
• Never discharge Li-Po cells to below 3V under load.
• Never cover warning labels with hook and loop strips.
• Never leave charging batteries unattended.
• Never charge batteries outside recommended levels.
• Never charge damaged batteries.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or cold places
(recommended between 40–120° F) or (5–49° C) or place in direct sunlight.
Low Voltage Cuto (LVC)
Low voltage cutoff (LVC) protects the Li-Po battery from over-discharge in flight
and activates when the battery reaches a preset value. When the battery is
discharged to the cutoff point, the aircraft will display rapidly flashing red, green
and blue LEDs to warn you it’s time to land. When you see this LED code, land
immediately to prevent over-discharge and damage to the battery.
When the LVC is activated, you have approximately 2 minutes until the battery is
depleted and can no longer maintain a hover. Repeated flying to LVC will damage
the battery.
NOTICE: Crash damage and battery damage are not covered under warranty.
IMPORTANT: Always disconnect and remove the Li-Po battery from the aircraft
after each flight. Charge your Li-Po battery to about half capacity before storage.
During storage, make sure the battery charge does not fall below 3V per cell.
A connected battery will result in trickle discharge.

5EN
The Battery Charging Process
1. Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not damaged e.g., swollen, bent, broken or punctured.
2. Attach the input cord of the charger to an appropriate power supply, such as a 12V battery or 12V DC power supply.
3. When the Li-Po charger has been correctly powered up, there will be an approximate 3-second delay, then an audible “beep” and the green (ready) LED will flash.
4. Turn the control on the Amps selector so the arrow points to the charging rate required for the battery (the 2200mAh Li-Po battery will charge at 2.0 amps).
DO NOT change the charge rate once the battery begins charging.
5. Move the cell selector switch to 3-cell for your battery.
6. Connect the balancing lead of the battery to the 3-cell (4 pin) charger port and press the Start button to begin battery charging.
7. The green and red LEDs may flash during the charging process when the charger is balancing cells. Balancing prolongs the life of the battery.
8. When the battery is fully charged, a beep will sound for about 3 seconds and the green LED will shine continuously. Attempting to charge an over-discharged
battery will cause the charger to repeatedly flash and beep, indicating an error has occurred.
9. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fire.
NOTICE: If using a battery other than the included Li-Po battery, refer to your battery manufacturer’s instructions for charging.
IMPORTANT: Consult local laws and ordinances before installing and operating any type of photograph-capable or video recording device in this product.

Binding
• If you purchased the ready-to-fly (RTF) model, the transmitter is bound to the model at the factory. If for any reason the model needs to be re-bound, follow the
directions for the Bind-N-Fly®(BNF) version below.
To bind or re-bind your 350 QX to your chosen DSM2/DSMX transmitter, please follow the directions below along with the binding instructions
included with your transmitter:
®
The Binding Process
1. With the transmitter and quadcopter powered off, connect the battery
to the 350 QX.
2. With the 350 QX on a level surface, turn on the power switch and allow
the quadcopter to initialize.
3. Wait until the blue LED on the quadcopter flashes rapidly, signaling the
quadcopter is initialized and ready to bind.
4. Ensure throttle is in the low position and throttle trim is at neutral.
5. Hold the control sticks in the desired bind position (see illustrations)
and press/pull the bind button/switch, then power on the transmitter.
6. Refer to the Flying LED Codes table to ensure the aircraft is bound
correctly.

IMPORTANT: Do not attempt to bind with more than one bind code.
Binding with more than one bind code will only allow the aircraft to
bind normally.
Unless binding with a bind code, the elevator and aileron inputs (includ-
ing trim) must be neutral during binding. If you are attempting a normal
bind with any input other than neutral, the aircraft will emit a constant,
rapid beeping sound.
Transmitter Bind Codes
Entering Bind Mode
If your 350 QX emits a constant beeping sound after binding
(Smart or Agility Mode only):
1. Ensure all trims are neutral.
2. Slowly move the elevator stick back and forth (close to center) and
listen for the beeping to stop or hesitate. Take note of the direction
you are moving the stick when the change of tone happens.
3. If the tone never changes with elevator movement, slowly move the
aileron stick back and forth (close to center) and listen for the beep-
ing to stop or hesitate. Take note of the direction you are moving the
stick when the change of tone happens.
4. Input trim in the direction that caused the change in tone until the
beeping stops.
In the event you cannot find an input that stops the tones:
1. Apply 1 click of elevator trim in either direction and then slowly
move the aileron stick close to center.
2. Continue to add 1 click at a time of elevator trim, up to 5 trim steps
off center up or down, and move the aileron stick until you find the
point that makes the tones stop.
3. Add aileron trim in the direction you moved the stick to make the
tones stop.

Flight Modes Explained
Flight Mode 0– Smart Mode (Default)
(Solid Green Indicator LED)
Stick Relativity– While in Smart Mode, the
path of the aircraft will always follow the control stick
input direction relative to the SAFE Circle, regardless of
the direction the nose of the aircraft is pointing.
• SAFE Circle™
–In most scenarios, the quad will not
enter the SAFE Circle.
• Position Hold– The aircraft will hold its position
when elevator and aileron inputs are at neutral.
• Self-Leveling– Brings the 350 QX to a level attitude
when the elevator and aileron inputs are at neutral.
• Altitude Command– Altitude is relative to throttle
stick position.
Flight Mode 1–Stability Mode
(Solid Blue Indicator LED)
• Self-Leveling– Brings the 350 QX to a level
attitude when the elevator and aileron inputs are
at neutral.
• Position Hold– The 350 QX uses GPS to hold a
given location when this function is activated. If
GPS is enabled and has a solid lock, the aircraft will
hold its position when elevator or aileron inputs are
at neutral.
• Throttle provides proportional thrust– The throttle
responds directly to the throttle input, giving the
pilot direct control over hovering as well as ascent
and descent rates.
Flight Mode 2– Agility Mode
(Solid Red Indicator LED)
• Aerobatic– Capable of flips and rolls
• Throttle provides proportional thrust– The throttle
responds directly to the throttle input, giving the
pilot direct control over hovering and ascent and
descent rates.

Stability and Agility Mode Control Inputs
The Blade 350 QX flies very differently in the different flight modes. Beginners should
use Smart Mode to start and progress slowly into Stability Mode. When flying in
Smart Mode, the quadcopter follows stick input based on the set pilot location. When
flying in Stability Mode, the quadcopter follows stick inputs based on the orientation
of the aircraft. The transition from Smart Mode to Stability Mode can be a challenge
for new flyers because the pilot will need to learn how to interpret the aircraft’s
orientation.
This aircraft is extremely sensitive to control inputs in Agility Mode and has NO self
leveling. We recommend you fly at low rate settings for the first few flights until you
are familiar with its response. For pilots new to quadcopters and helicopters, familiar-
ize yourself with the Blade 350 QX in Smart Mode and at low rate.
As you become more familiar with the quadcopter’s response, adjust the rates and
expo to suit your flying style (if using a computer radio).

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 fly 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 fly 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 flight, 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 flight control system loses its
orientation because of aggressive flight 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 flashing 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 flashing 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 flashing LED)
If the 350 QX is in this mode and the GPS fails, it will not affect flight 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 flying, it will turn off the mo-
tors and disarm.
• If the 350 QX is flying and has a good GPS lock with a home position set,

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 flying.

13 EN
Preparing the 350 QX For Flight
CAUTION: When the home location is set (step 6), the 350 QX must be approximately 16 feet (5 meters) from where the pilot will stand during flight, pointing
away from the pilot. If the aircraft is pointed in any other direction, the SAFE Circle feature will not function as expected and may result in personal injury or
damage to property. Once the aircraft’s motors are started, do not change your position.
1. Power on the transmitter with the flight mode set to
Smart Mode, the throttle stick down and the throttle
trim at neutral.
2. Install a charged battery, plug it in and close the
hatch.
3. With the quad on a level surface, turn on the power
switch and allow the 350 QX to initialize.
If the GPS is enabled, wait for the GPS signal to be
acquired, which is indicated by a solid green LED.
It may take from 30–90 seconds to acquire a GPS
signal.
IMPORTANT: While in Smart Mode the motors will
not start if a GPS signal has not been acquired.
4. Move the aircraft to the desired home location and
orient the aircraft pointed away from the pilot.
5. Step back approximately 16 feet (5 meters) from the
home location.
6. When you are prepared to fly, quickly move the rud-
der stick all the way left and then all the way right.
The props will begin to spin. The home position for
GPS functions is set and your aircraft is ready to fly.
IMPORTANT: The motors will not start if the transmit-
ter is set to low rate. The dual rate switch must be set
to high rate.
Lower the throttle stick and the throttle trim to power
off the props after flight.

Flying the 350 QX
Takeoff
Increase the throttle slightly above low stick (10–15%).
The 350 QX altitude in Smart Mode corresponds to the
throttle position. Low throttle is on the ground, slightly
raising the throttle will produce a low hover, and the
higher the throttle position, the higher the 350 QX will
ascend until it reaches its maximum altitude (approxi-
mately 45 meters).
Explore the flight envelope of the 350 QX in Smart
Mode without fear of losing orientation. See the
diagrams in the Flight Modes Explained section for
more details on the aircraft’s function in Smart Mode.
In Smart Mode, the direction the aircraft is pointing
does not affect the control, and the aircraft’s response
relative to you (the pilot location) does not change with
orientation. Stability Mode and Agility Mode operate
more like a conventional RC helicopter or multicopter.
IMPORTANT: Aggressive flight in Agility Mode will
significantly reduce flight time.

Return Home
• When this feature is activated, the 350 QX will
fly back to its assigned home location and
land. After landing, the motors may take up to
5 seconds to disarm. If the motors take more
than 20+ seconds to disarm, perform the
Pressure Sensor Calibration.
• To restart the props after landing in Return Home,
fully lower the throttle and ensure the throttle trim is
neutral, then quickly move the rudder stick fully left
and then fully right.
CAUTION: The 350 QX will not recognize the
SAFE Circle feature when Return Home is
used. Activating Return Home may cause the 350 QX
to fly directly over the pilot if the aircraft was flown to
a position behind where the pilot was standing when
the home position was established.
TRAINER
Activating Return Home
Press and hold.
Releasing the switch
will stop the Return Home
program.
Landing
To land the 350 QX there are two options:
• Guide the aircraft to where you wish to land and
reduce the throttle. Reduce the throttle trim after
landing to disarm the motors.
• Activate the Return Home function to return the
350 QX to the assigned home location and land
automatically.
CAUTION: Do not activate the Return Home
function if the 350 QX is showing the low
battery indication. Manually land the aircraft
immediately.
After Your Flight
1. Turn off the power switch on the 350 QX.
2. Turn off the power to your transmitter.
3. Unplug and remove the battery from the 350 QX.
CAUTION: Always disconnect the Li-Po bat-
tery from the aircraft when not flying to avoid
over-discharging the battery. Batteries discharged to a
voltage below the lowest approved voltage may become
damaged, resulting in loss of performance and potential
fire when batteries are charged.
Location alert
The motors will Beep under the following conditions:
• At any time the props stop spinning after they have
been initialized.
• After 30 seconds of no throttle input (waiting armed
on the ground).
This will alert the pilot to the location of the aircraft if it
lands in a location with low visibility.
Beeping will continue until the battery can no longer
supply enough power to the motors.
If the quadcopter crash lands and one or more motors
are stopped by an impact, the quadcopter enters
emergency mode. The LED will flash white and the
motors will beep loudly.

Airframe Maintenance
Replacing the body
Disassembly of the old airframe
1. Ensure the battery is disconnected from the
quadcopter.
2. Remove the 2 machine screws from each propeller
and remove the propellers.
3. Remove the 32 1.5mm hex screws from the bottom
of the frame to separate the upper and lower body
pieces.
4. Unplug the compass sensor from the flight control
board. Remove the landing gear with compass sen-
sor and place it in a safe area away from magnets.
NOTICE: Do not allow the compass sensor to
get near a magnet. Any magnet, including those in
the 350 QX motors, can damage the compass and
cause it to work incorrectly. If the 350 QX is flown
with a faulty compass, all GPS functions will be
compromised.
5. Unplug the GPS receiver from the flight control
board and remove the battery tray assembly.
6. If you are replacing the GPS components, remove
the foil from the GPS receiver and unplug the GPS
antenna from the GPS receiver.
7. Remove the flight control board from the airframe.
8. Remove the motors and ESCs from the airframe.
Before installing the components into the new airframe,
inspect all the components for any obvious damage or
burnt smells. Check the motors for smooth bearings
and inspect all the propellers for chips, burrs or cracks.
Replace any parts in question.
Installing components in the new airframe
1. Install the motors and ESCs, making sure to match
the wire colors on the connectors.
2. Install the flight control board.
3. Install the tray assembly.
4. Install the GPS receiver and GPS antenna and plug
the cables into their corresponding sockets.
5. Assign the motors and ESCs according to the
ESC and Motor Assignment Procedure.
6. Install the landing gear and connect the compass
to the flight control board. If you replaced the
compass or believe that it may have been impaired
by a magnetic field, you will need to perform the
compass calibration procedure.
7. Mount the top of the airframe.

Compass Calibration Steps
Compass Calibration
Pressure Sensor Calibration
Accelerometer Calibration
The Flight Controller on the 350 QX has automatic magnetic declination calibra-
tion, so you will not have to worry about looking up the magnetic declination at
your location and changing settings on your 350 QX to get accurate compass
measurements. It is possible, however, that your compass may need to be cali-
brated if it is exposed to strong magnetic fields.
Compass calibration procedure:
1. Go to an open space outdoors away from metal. Take a conventional com-
pass with you to ensure you know the direction of north.
2. Ensure your transmitter is off and then connect a flight battery to the 350
QX. Power the aircraft on. Wait five seconds and then the blue LED will
begin flashing rapidly, signaling the aircraft is initialized and ready to bind.
3. Once the blue light begins flashing, bind with yaw stick left. The 350 QX LED
will slowly flash between red and green for 5 seconds.
4. Put the 350 QX flat in your hands and face north. After 5 seconds of slow
flashing the quad will start flashing rapidly. The quad is now collecting data
to be used for the calibration.
5. Slowly rotate the quad 360 degrees about the east-west axis (“flip” the
aircraft either forward or backward) until it is flat in your hands again.
6. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing north-west.
7. Slowly rotate the quad 360 degrees about the east-west axis, (“flip” the
aircraft diagonally either direction) until it is flat in your hands again.
8. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing west.
9. Slowly rotate the quad 360 degrees about the east-west axis (“flip” the
quad sideways either direction) until it is flat in your hands again.
10. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing south-west.
11. Slowly rotate the quad 360 degrees about the east-west axis (“flip” the
aircraft diagonally either direction) until it is flat in your hands again.
You have 30 seconds to complete the procedure. The 350 QX should still be
blinking rapidly when you finish. Hold the aircraft still until it stops blinking rap-
idly. If successful, the 350 QX will beep a positive confirmation and then restart
itself. If unsuccessful, the 350 QX displays the failed calibration code, a solid
white LED. If the 350 QX displays this error code, power off the aircraft and then
begin the calibration procedure again.
The pressure sensor is calibrated at the factory on the 350 QX. Recalibration
should only be necessary if you replace the sensor.
1. Place the 350 QX in a cold area. Allow it to remain in the cold for 30 minutes
or more.
2. Bring the 350 QX out of the cold and into a warm area. The greater the differ-
ence in temperature between the cold and warm areas, the more accurate the
calibration will be.
3. Ensure your transmitter is off and then connect a flight battery to the 350 QX
and power the aircraft on. Wait five seconds and then the blue LED will begin
flashing rapidly, signaling the aircraft is initialized and ready to bind.
4. Once the blue light begins flashing, bind with yaw stick right. The 350 QX 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.
5. 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 QX displays the failed calibration code, power off the aircraft and then
begin the pressure calibration procedure again.
To calibrate the accelerometer, the quadcopter needs to fly for 20 seconds while
being level. This allows the accelerometer readings to be averaged and stored in
memory.
Use the following procedure to calibrate the accelerometer:
1. Power on the quadcopter with the transmitter off to enter bind mode.
2. Turn on the transmitter while holding the elevator stick back and pressing
the bind switch.
3. Set the flight mode switch to Stability Mode or Smart Mode. The quadcopter
will fly in Stability Mode no matter which position is selected.
4. Start the motors. Fly the quadcopter off the ground. The quadcopter LED will
flash slowly (red, green, blue).
5. Use trims to adjust roll/pitch so the quadcopter does not drift left/right and
forward/back.
6. Activate the accelerometer calibration mode by changing the flight mode
switch into Agility Mode. The vehicle will still fly in Stability Mode. The LED
will start flashing quickly (red, green, blue).
7. Fly steadily for 10–30 seconds. The LED will flash slowly when data
collection is done.
8. Land the quadcopter and stop the propellers by lowering the throttle and
throttle trim.
IMPORTANT: The calibrated values are not yet permanently stored. Do not turn
off the quadcopter.
9. Center the trims on the transmitter. Start the motors and verify the
quadcopter flies without drifting.
10. Land the quadcopter and stop the motors by lowering the throttle and
throttle trim.
11. Save the calibration by moving the rudder stick quickly left, right, left, right.
Values are saved when you hear a rapid triple tone twice.
12. Turn off the quadcopter.
13. Confirm the calibration by powering up the quadcopter and performing a test
flight. If the calibration is not correct, start the calibration procedure again.

ESC and Motor Assignment Procedure
Motor Numbers 1. Begin with the transmitter off and connect a flight
battery to the 350 QX.
2. Power on the quadcopter on a level surface and wait for
the rapid blue flashing LED to indicate the aircraft has
entered bind mode.
3. With the throttle stick in the full throttle position, press/
pull the bind button/switch and power on your transmitter.
The quadcopter will acknowledge the assignment mode
with a loud high, then low tone. If your transmitter is
equipped with a high throttle warning at startup, it is nec-
essary to disable this alarm prior to completing this step.
After the replacement procedure is complete, re-activate
the high throttle warning in your transmitter.
4. The motor number and prop direction are molded in the
top of the body. The motors will give an audible “beep” to
indicate which motor to calibrate. When the motors beep
1 time, spin motor 1 by hand. The motor will respond with
the same number of tones upon successful assignment.
5. When the motors beep 2 times, spin motor 2 by hand.
6. When the motors beep 3 times, spin motor 3 by hand.
7. When the motors beep 4 times, spin motor 4 by hand.
When the assignment is successful, the quadcopter enters
emergency mode. Restart the quadcopter.
