# Step 

# 5 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 flyba rless 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 ex it from the auto trim flight mode.

STEP6 You may now fly your helicopter without power cycling.©2012 DJI Innovation s . All Rights Reserved. 8 | 

# Step 

# 6 Control Mode Knowledge

When you use the NAZA

- H system, there are three control modes for selection. NAZA

- H can work in M anual

M ode and ATTI. M ode without a GPS module. After connection to the GPS module, GPS ATTI. M ode 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 fligh t 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 M ode 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 to ATTI. Mode or GPS ATTI. Mode , the NAZA will 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

swit ch to the M anual M ode 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 Ma ke sure to take off the helicopter in Manual M ode 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.©2012 DJI Innovation s . All Rights Reserved. 9 | 

# Step 

# 7 Test Flight

Not e :

 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

- c heck ing 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 the Auto Trim f light after you have completed a successful test / trim flight.

 Do not enter ATTI. Mode /GPS ATTI. Mode flight immediately after violent 3Dflight.

 Make sure the compass has been calibrated before GPS ATTI. Mode flight.

 Read the LED description in the appendix get more accurate understanding of the controller. 

### F irst, carry out Manual Mode Test Flight (Adjust the tail gyro gain in Manual Mode if required.)
STEP1 Make sure all connection s are correct and firm
, and all batte ries are fully charged and then tur n on the R/C transmitter

. STEP2 Place you r helicopter on a horizontal surface and p ower on the NAZA

STEP7 Hover your helicopter, and switch to ATT I

. Mode

. STEP8 Finish and land the helicopter in Manual Mode

. 

### Select GPS ATTI. Mode Test Flight i f GPS module is used (M ake sure that all the autopilot parameters have been configure d in the Common page of the Assistant Software.) STEP9 Swit ch to GPS ATTI. Mode , make sure the green LED is blinking

. STEP10 Red LED maybe blink , which indicates that the NAZA

- H is still acquiring GPS satellite signal s , wait

until the red LED is off, meaning the NAZA

- H have found more than 7 GPS satellites. STEP11 Switch the system to Manual Mode and tak e
- off and fly your helicopter in Manual Mode

. STEP12 Hover your helicopter, and switch to GPS ATT I . Mode

. STEP13 Finish and land the helicopter in Manual Mode
