Step4 Digital Compass Calibration
Please calibrate the compass using the following steps, if the GPS module is used, else skip.
STEP1 Quickly switch the control mode switch from Manual Mode to GPS ATTI. Mode for 6 to 10 times
(Manual Mode -> GPS ATTI. Mode -> Manual Mode is one time) and the LED indicator will be
constantly on in yellow .
STEP2 Rotate you helicopter around its horizontal axis until the LED lights green constantly.
STEP3 While the green LED is constantly on, hold your helicopter vertically and rotate it around its
vertical axis, keep rotating until the green LED is off, meaning the calibration is finished.
STEP4 After you finished the calibration, the LED indicator will show whether the calibration is successful
or not:
If calibration was successful, calibration mode will exit automatically.
If the LED keeps blinking red quickly, the calibration has failed. Switch the control mode switch
one time to cancel the current calibration, and then re-start from the step 1 for re-calibration.
Important:
Please complete the calibration in an open area.
If you keep having calibration failure, it might suggest that there is very strong magnetic interference
around the GPS & Compass module, please avoid flying in this area.

Step5 Auto Trim Flight Knowledge (Only for Flybarless)
Auto Trim flight is to eliminate any bias of the mechanical neutral position, in order to achieve better 3D flight
performance, especially rotation flight performance. Please complete the auto trim flight in calm air weather,
after the first successful test / trim flight and after mechanical adjustment.
Tips:
Auto Trim flight is only for flybarless types of helicopter.
You may not need to do auto trim flight if the mechanical neutral position is precise enough or only
for normal flight (non 3D).
STEP1 Make sure all connections are correct and connected firmly, and all batteries are fully charged
and then turn on the R/C system.
STEP2 Quickly switch the G channel switch from Tail Locked to Non Tail Locked for 3 to 5 times.
STEP3 The red LED is on and the tail starts the initialization movement, DO NOT moves the helicopter or
the TX sticks during this time.
STEP4 Take-off and hover your helicopter in Manual Mode, using as little R/C transmitter stick movement
as possible during this hover flight.
STEP5 Hover the helicopter for about 1~2 minutes until the red LED turns off, and the system will exit
from the auto trim flight mode.
STEP6 You may now fly your helicopter without power cycling.

Step6Control Mode Knowledge
When you use the NAZA-H system, there are three control modes for selection. NAZA-H can work in Manual
Mode and ATTI. Mode without a GPS module. After connection to the GPS module, GPS ATTI. Mode is
available. Please pay attention because the GPS ATTI. Mode is dependent on the number of GPS satellites
acquired by the main controller.
Different control modes will give you different flight performances. Please make sure you understand the
features and differences of the three control modes.
Manual Mode
In Manual Mode, all the operation is the same as normal helicopter, depending on experience.
It is appropriate for 3D flight. Select Manual Mode for Auto Rotation flight.
ATTI. Mode /GPS ATTI. Mode
The Roll and Pitch stick command form the R/C TX corresponds to the Roll and Pitch angle of the
helicopter.
The Yaw stick command form the R/C TX corresponds to the rotation velocity of the helicopter and the
rotation velocity is slower than in Manual Mode.
When you switch toATTI. Mode or GPSATTI. Mode, the NAZAwill record the hover pitch stick position.
The command of this stick now corresponds to the vertical velocity of the helicopter.
In GPS ATTI. Mode, keep the Tx sticks at the center position, the helicopter will hold position in the
horizontal direction.
When you switch to ATTI. Mode or GPS ATTI. Mode, the NAZA will record the throttle position. The
throttle will hold this position while in ATTI. Mode or GPS ATTI. Mode, so the motor rotation speed
cannot be changed. The motor will not stop even if the throttle stick is at the bottom position. Please
switch to the Manual Mode if you need to change the motor rotate speed or even stop the motor.
Has the function of auto level fail safe and low-voltage alarm.
How to enter the different control mode?
STEP1 Use a 3-position switch on the TX as mode control switch.
STEP2 Make sure to take off the helicopter in Manual Mode in every flight.
STEP3 Hover the helicopter if the Manual Mode flight is normal. Release all joysticks and then flip the
control mode switch to the ATTI. Mode or GPS ATTI. Mode, the Tx stick neutral positions are
recorded automatically.
Note: Do not move any Tx joystick when switching the mode switch, and do not switch the mode
switch while the helicopter is flying inverted.
* This is the standard way to enter the ATTI. Mode and the GPS ATTI. Mode, please refer to the assistant
software for more details.

Step7 Test Flight
Note：
When the system is powered on, DO NOT move your helicopter or sticks on the R/C transmitter until
the system initialization has finished (about 5 seconds).
Do NOT move any command sticks during the system start and self-check procedure! Please contact
us if the last four green blinks are abnormal.
After power on, if the LED blinks Red, Yellow and Green continually, that means the IMU initialization
and self-checking is abnormal. The NAZA-H will not work, please connect to the Assistant Software
for checking.
You may need to adjust the gain of the tail gyro using the R/C transmitter.
For the first flight of a flybarless helicopter, please finish theAuto Trim flight after you have completed
a successful test / trim flight.
Do not enter ATTI. Mode /GPSATTI. Mode flight immediately after violent 3Dflight.
Make sure the compass has been calibrated before GPSATTI. Mode flight.
Read the LED description in the appendix get more accurate understanding of the controller.
First, carry out Manual Mode Test Flight (Adjust the tail gyro gain in Manual Mode if required.)
STEP1 Make sure all connections are correct and firm, and all batteries are fully charged and then turn on
the R/C transmitter.
STEP2 Place your helicopter on a horizontal surface and power on the NAZA-H and electric devices on the
