High performance external IMU

T1-PRO uses high-performance external IMU. The IMU incorporates an ADI single-axis analog gyroscope and accelerometer, which can achieve superior control accuracy. The ADI gyroscope's excellent vibration suppression performance is extremely advantageous for smooth flight of the aircraft when there are severe shocks. Therefore, compared with the existing industrial-grade commercial flight controller, T1-Pro is more stable and reliable.

Vibration dampening design

In order to further improve the performance of T1-PRO, the structure of external IMU has been specially designed. The design of the counterweight and multi-layer dampers have minimized the interference of the vibration to the gyroscope. The unique anti-interference hydrostatic cabin design has eliminated the influence of the clutter airflow on the barometer. All the design make the measurement of IMU internal sensor data more accurate and improve the flight stability.

Temperature compensation

T1-PRO uses advanced sensor temperature compensation algorithm and industrial precision calibration algorithm to further broaden its high-performance range.

Double redundancy structure

T1-Pro uses a dual IMU and dual GPS design. During flight, when the external IMU operates abnormally, the flight controller will switch to the internal IMU, which is to ensure the safety of aircraft. Dual GPS module supports GPS, GLONASS and BDS three-mode positioning, which can search more stars and achieve more accurate positioning.

Multiple flight functions

T1-PRO flight controller supports the intelligent navigation, tapfly, waypoint planning, regional flight and other functions, which makes the simple aircraft manipulation.

Failsafe Function

When the receiver loses signals, the system will trigger failsafe mode, and the aircraft will return to the takeoff point.

Low voltage alarm and protection

In order to avoid serious consequences such as crashing which are caused by low battery voltage , T1-Pro flight controller designs two level low voltage protection measures to support user-defined settings. When the battery voltage drops to the first level protection voltage, the led flash yellow light warning; when the battery voltage drops to the second level protection voltage, the led flash red light warning and the aircraft would land automatically to prevent crashing.

Motor stopping and propeller breaking protection

For hexa-rotor or above aircraft, the T1-Pro flight control system has the ability to protect the aircraft when a propeller is broken. Under the premise of sufficient power, when the aircraft accidentally lose the impetus output of a certain propeller, the aircraft can continue to maintain the flying posture by sacrificing the control of the yaw axis. At this point, the aircraft can continue to be manipulated and return safely, which greatly reduces the risk of crashing.

Open SDK

Users can freely expand the hardware and software development, which may enlarge the application of UAV.

T1-ProMulti-rotor flight controllerFAQ

Home Flight control products T1-Pro FAQ


  • Calibration accuracy of magnetic compass isn’t workable.

    1、Setting problem of remote controller

    Solution: check whether setting remote controller channel is correct.

    2、Flight controller doesn't enter in calibration mode


    (1)Correct operation of the dial and rotation . Follow instruction sheet

    (2)Check whether there is a metal magnet around, such as strong magnetic interference.


    3、Calibration rotation angle is not correct or speed too fast

    Solution: keep horizontal and vertical rotation, it is better to keep the speed which is not very fast.

    4、Hardware problem

    Solution: contact manufacturer to solve problem and replace new hardware

  • The speed of connecting navigation satellite is slow.

    To get signal from 7 satellites, it takes 1 minute in cold start and 20 seconds in hot start. Because the GPS module only uses the high quality GPS signal, so the signal quality requirements are higher.


    1、The weather condition has a certain degree of influence on the search speed.

    2、Shelter from high objects

    Solution Use in wide and open place 

  • Unable to unlock?

    1、The channel of receiver and remote controller is wrong.

    Solution:Check the channel of receiver and remote controller is correct..


    2、The remote controller calibration is wrong

    Solution:Recalibrate the remote controller and check whether sliding block of software is in position(Pitch channel goes down then sliding block goes to the right )

    3、The idle speed of some ESC is high that can not reach the minimum deblocking idle speed.

    Solution: Push the throttle to see whether there is motor rotation, if yes, it is ok to use

    4、Wrong ESC

    Solution :calibrate ESC (follow instruction sheet)


  • There are inconsistencies between remote-control lever and flight controller.

    1、The remote controller calibration is wrong



    Recalibrate the remote controller and check whether sliding block of software is in position(Pitch channel goes down then sliding block goes to the right )


    2、Mis connection


    Check whether the electrical wiring sequence and positive and negative propeller of the installation is correct.


  • How to do when aircraft fuselage is tilt?

    1、The remote controller calibration is wrong

    Solution:Open software to adjust parameter then recalibrate remote controller

    2、Horizontal calibration

    Solution: Follow instruction sheet

    3、Mis connection


    Solution:Check whether the electrical wiring sequence and positive and negative propeller of the installation is correct.

  • How to do if aircraft doesn’t go straight?

    1、Magnetic compass error

    Solution: recheck magnetic compass


    2、The remote controller calibration is wrong


    Solution   Recalibrate remote controller 

    3、Blade damage

    Solution Replace blade

  • How to do when there is deviation in mode of positioning ?

    1、Frame is affected by vibration

    Solution Fix the frame, fold paddle connection pieces and reduce the frame vibration

    Solution fix frame

    2、Affected by heavy wind

    3、Affected by ground effect at low flight attitude

    Solution : up to the higher attitude

    4、There is error in remote calibration ,because the pole position is not in the middle.


    Solution: recheck remote controller


    5、 poor GPS signal

    Solution: choose the wide and open place to fly


  • How to do when there is a big deviation in automatic-return?

    1、There is no GPS signal when it takes off and some difference between return point and actual start point.


    (1)get the GPS signal steadily before takes off

    (2)The orientation of the aircraft can be adjusted during back to the takeoff point, but not its position.In the landing process to the take-off point, its orientation can be adjusted by turned over, pitch and heading shift. 

    (3)You can exit by click the button of ‘Return’ or shift attitude mode.

    2、   poor GPS signal

    solution: choose the wide and open place to fly

  • The multi-rotor takes wrong nose head in mode of intelligent orientation.

    1、operator position moving

    Solution:recognize original heading orientation after moving

    2、Heading orientation is not as same as operator’s forwarding position when it takes off

    Solution: recognize the orientation of heading, it is better to keep the same orientation with operator


  • How to set intelligent orientation and automatic-return?

    Intelligent orientation: 

    when CH5 channel at 2 switch,the low place is attitude mode;the  high one is GPS mode;

    When CH5 channel at  3 switch, the low place is attitude mode;the middle one is intelligent orientation mode;the  high one is GPS mode;


    CH6 channel can be fixed as a button of auto-return. You can turn off controller power to check whether sliding block is in the lost-control position when adjust parameter.


  • What’s the longest distance between shafts that multi-rotor is workable in wind resistance?

    1、Generally, it can hold 4-grade wind , but there are still some  differences depending on the aircraft wheel base and weight.

    2、Test the wheelbase can be up to 1600 mm, it is recommended that the user select the frame within1000 mm

  • When software used for adjust parameters is not workable, how to figure it out?

    1、Whether installment is right or wrong.


    ⑴Check whether installment of software driver is fit for operation system.

    ⑵ Connect flight controller with computer, check whether thereis port number for            port in device manager.

    ⑶Turn off power and restart.

    2、Check whether USB wire damaged.


    Replace USB wire

    3、Problems caused by operation system


    It’s recommended to use original or purified operation system, because some non-official operation systems lack of of files.
