(1) This product is suitable for those adults who have model plane operating experience.
(2) Do not fly in bad weather, such as windy, snowy, foggy etc..
(3) Select the open, no-tall-buildings and mine area. Extensive use of steel buildings will affect the compass
Work, blocking the GPS signal, causing worse on the aircraft positioning or even not able to locate.
(4) Please keep away from highly spining parts(such as propellers and motors).
(5) Please keep away from obstacles, people, water and so on.
(6) Do not fly it in where there is high-voltage lines, communication base stations or radio towers, in order to
avoid signal interference.
(7) Don't fly in no-fly zone according to the local laws and regulations.
(8) Flight performance will be affected when flying it with altitude of 4500 meters,
as the battery and gravity system will be influenced.

e IMPORTANT: The first couple of flights, you may experience the aircraft drifting,
This is normal, please continue to fly the aircraft manually, while the system refines the calibration. After 5-10 minutes land,
lock the motors, to save the improved settings.
Notice: The slight drifting may continue for a couple of batteries, you will notice significant improvement in GPShold & stability after 4-5 batteries.
Notice: Always perform the calibration away from eletric fields and metal surfaces.
Trivia: Different brands have different calibration processes, the process is typically refered to as “the Calibration Dance”.

It is highly recommended that you wait for “triple blink” 8 statelites before starting the flight.
NEVER attempt to AUTO-START with less than “triple blinks”
8.4 Motor Unlock / Lock Mode1 (Throttle stick on the right) | Mode2 (Throttle stick on the left)
e Motor Unlock
After binding the DEVO F12E to the QR X900, Check that all trims 4
are neutral, the throttle stick is ALL the way Down with the display Rudder stick to stick Throttle / Rudder ioe EV stick
indicating 0% throttle. Check that ALL switches are in the UP position.
Note: that you can start the motors in the Manual Mode or the GPS-HOLD MODE.Gently push the throttle stick down and move
the rudder (YAW) stick to the left side. (on mode 2 radios throttle and rudder is the same stick)
You will see the RED indicator LED turn on, indicating that motors are unlocked.
Be very careful at this point, as pushing the thottle up will start the motors. You can test by pushing the stick up a little, the motors
should start. For your safety, the motors will dis-arm again after 10seconds.
e Motor Lock
Lock the motors by moving the throttle stick all the way down and the rudder (YAW) stick all the way to the right.
The RED LED light will go out when the motors are disarmed.
TEST: push the throttle stick up a little, the motors will not start when locked.
* The motors are LOCKED by default after successful binding.
* Motors can be unlocked or locked in GPS-hold mode.
if you land in GPS mode, move the “MIX” switch to position “0”

(1) NEVER use this mode with less than 8 satelites locked, you should see BLUE TRIPLE BLINK.
(2) Before switching mode, always put the throttle stick to middle position ( 50% ).
(3) IF the GPS signal degrades, the QR 900 will automatically enter “Altitude hold mode” note in this mode it will drift, but will hold its altitude.
After flying 50% of the battery, do NOT switch from GPS mode to Manual, this may cause a sudden drop / crash.
You can land in GPS mode, after landing, keep the throttle stick DOWN and switch to manual, then lock the motors.

To REGAIN control of the QR X900, make sure the throttle is centered, then flip the MIX switch to position “1” . In
an emergency such as losing the control link between the F12E and the QR X900, the Failsafe system will automatically

Hyper IOC Mode
IOC or Intelligent Orientation Control mode means that the aircraft's flight direction is only relative to the
orignal take-off point (where you armed the motors). REGARDLESS of the actual aircraft headding, in this
mode you can fly past something and pan the aircraft to frame your shot, without having to worry what
direction the aircraft is facing.

Fly the QR X900 manually beyond 10 meters using the GPS mode, then activate the IOC mode, the QR X900 will now fly
IOC until you change the mode, you can pan freely for video shots, when you push the stick right or left, the QR X900 will
move sideways relative to the original take-off position. Pushing the pitch stick up will push the QR X900 away from you,
pulling the stick back brings the QR X900 back to the starting point. When flying in IOC mode, you can make the QR Х900
return to the starting point simply by pulling the stick toward you.
WARNING: The IOC turns off when the aircraft gets closer than 10meters to the take off point. Be prepared for this, as the
system will switch back to GPS hold mode at that point. This switch can cause confusion if the pilot are not prepared.

11.4 Methods for transferring QR X900 from 6-axis to 4-axis (as needed)
O Dismount M2 and M5 arms in the reverse order of arm installation, and disconnect the brushless motor
and brushless speed controller connection wires of M2 and M5. (Please refer to page 6-7)
©) Dismount M3 and M4 arms in the reverse order of arm installation, and disconnect the brushless motor
and brushless speed controller connection wires of M3 and M4. (Please refer to page 6-7)
Then exchange the installation position and connection port and start the new installation.
(that is to say, match M3 at M4, match M4 at M3)
(3) Please download the main controller program for 4-axis on Walkera official website.
Connection method: use the USB cable to connect the computer and the USB port on the main controller.
