Three ports of PMU module have same definition
GPS/COMPASS module installation
GPS/COMPASS module has a built-in GPS and compass, the compass is sensitive to magnetic
interference, should be far away from electronic devices, such as motor, ESC, battery and so on. The top
side should be facing up, with the orientation arrow pointing directly to the nose direction, mount it on the
bracket horizontally. Connect it to any one of the CAN ports of PMU. It is recommended to use bracket
included in package, otherwise, please make sure it is nonmagnetic.
The module built-in magnetic compass as magnetic sensitive equipment,please pay attention
to keep it away from the motor, ESC, power battery and etc when install and use.
LIU module installation
Mount in a good place to make sure the LIU is visible during flying, connect it to any one of the CAN ports
of PMU with the enclosed 3M adhesive tape.
OSD module installation

1.2Installation and test for adjusting-parameter software
Preparation before installation and configuration
T1 flight controller supports PC, Mobile phone to adjust parameters
If you do the configuration on phone, you only have to install phone app and buy bluetooth module, no
need to install any driver.

If you do the configuration on PC, it must meet below demands
support windows system Windows XP/7/8/10
PC has connected to the Internet.
Install latest adjusting-parameter software (It may need to install driver)
Install and test steps
Here follows the instruction of parameter setting steps, taking the settings of adjusting-parameter
software as example. You can see details of setting method according to the inner specification of
adjusting-parameter software.
Step1.Use USB cable to connect flight controller and PC.
PC will automatically detect flight control and connect it.
When using a USB to connect flight controller and PC, there should be power given to flight
controller.
Step2.Choose the type of aircraft, as shown in Figure 1-4.

Figure 1-4 Set the type of aircraft
(1) The direction of the red arrow indicates rotating clockwise (view from the top).
(2) The direction of the blue arrow indicates rotating anticlockwise (view from the top).
(3) To coaxial propellers: red propeller is at Top; blue propeller is at Bottom.
Step3.Choose the type of receiver and calibrate it
1.Choose the type of receiver you have.
2.Setup a new fixed wing model on transmitter, choose a three position switch for CH5, choose a two
position or three position switch for CH6.
3.Click the“START CALIBRATION”button, and move the stick of channel 1 to 4, the switch of 5 to 6,
throughout their complete range several times, then click the “FINISH CALIBRATION”button.
Remote control only unlock after the correct calibration, please check the channel direction is
correct or not:
turn the aileron stick to right, the roll cursor slides to right;
turn the rudder to right, the yaw cursor slides to right;
pull backward the elevator stick, the pitch cursor slides to right;
Push forward the throttle stick, the throttle cursor slides to right;
4.Switch CH5 mode switch, CH6 return switch，check if the position on software matches with the
control mode, whether return mapping is normal.
If the receiver type is not S.Bus, you need to do as follow:
1.Set the End Point of CH5 to 30%～70%
2.Set the rudder angle in the range of normal mode.
You can verify the Fail-Safe setting by shutting down the transmitter, the control mode will
automatically jump to red „Fail-Safe‟area.

Step4.Gain setting, , as shown in Figure 1-6.
1.Choose the axle base of aircraft which you are using，for your better flying experience，some
parameters have been set automatically according to the axle base of aircraft.
2.You can adjust adjust the sensitivity according to the instruction of adjusting-parameter software.
3.You can obtain the best sensitivity of flight by the process of „test flight and readjusting‟

Step5.Low-voltage protection setting, as shown in Figure 1-7.
If you do not want to use this function, you can turn it off, then the aircraft will only alarm with
LED blinking when the battery is low.The first level protection has yellow LED blinking, the
second level protection has red LED blinking.
If the low-voltage protection is turned on, the aircraft will return automatically during first
level protection, during second level protection the aircraft will land automatically.
No matter the auto-return or land in stand point, you can switch CH5 mode twice to
terminate low-voltage protection at any time .
If the low-voltage protection is triggered, you are unable to switch to any kind of flight
mode except for attitude mode and returning mode and landing mode.

1.3Unlock and lock
T1 has only one way to unlock the aircraft, follow the figure 1 to unlock no matter whether you are using
Japan TX or US TX, and follow the figure 2 to lock the aircraft. The aircraft will automatically lock after
landing with the throttle stick maintaining minimum for 3 seconds.
After ESC has calibrated by T1 flight controller, the motor will turn on according to the order
when you unlock the drone. When there is run-up of NO. 1 motor , all will turn on at the same
time after you push the throttle .
The idle speed of DJI series ESC is higher. There is no idle speed of motor when your use its
recommended idle speed. It can be solved when you shift it to the higher idle speed in motor
idle interface

1.4 ESC and compass calibration
ESC and compass can be calibrated by the switch combination of CH5 on the remote control.
If you adopt the method of separate power supply for motor and flight controller, you need to
cut the power for motor first, the power for flight controller later, when you want to do
calibration and repower it. After this, power can be provided for flight controller at first, motor
later.
ESC and compass can be calibrated by flipping stick, you may refer to Figure 1-8 and Figure 1-9 for
calibrating.

Procedure of
ESC clibration
Push the throttle stick to maximum
postion
Flip CH5 to minimum and maximum for
6～10 times quickly
keep the throttle postion unchanged,
reboot the MC
After the MC is repowerd, the motor will
beep twice, pull the throttle stick to
minimum position within two seconds

1.5Horizontal Calibration
For the first time before a test flight, put the plane on level ground and make it perform toe-out locking
action for 10 seconds. When the blue and green indicator of LIU is flashing alternately, you can loosen
remote controller. After about 10 seconds, there is only LIU blue indicators flashing, then 15 seconds later,
LIU is normal, which shows that the calibration is successful. Calibration process takes about 25 seconds
altogether. If the drone still on one side during the flight attitude mode, you are suggested to do horizontal
calibration once again.

2Fly test instructions
2.1Flight mode and corresponding responding
Channel CH5 can be two position switch or three position switch.When set to two position switch，top and
bottom position correspond to attitude mode and GPS mode; When set to three position switch,
bottom-middle-top position correspond to attitude mode and intelligent direction mode and GPS mode.
Attitude mode and GPS mode are used most generally for common flight. The response relationship
between the remote controller and the action of aircraft is shown in table 2.1.
