F/W Version 2.1 

 

 

A3X Pro Expert Flight Control System   

User Manual 

  Version 2.1 

 

 

 

 

 

 

 

 

 

 

 

Software has been improved to allow you to reverse the gyro direction for aileron 2 and elevator 2 

independently now, which will give you more flexibility to setup your plane when using a dual aileron or 

elevator system. 

 

A new feature called “Brown-out Fast Recovery” is added to improve the reliability. When an 

unforeseen power failure occurs such as a voltage drop or interruption from the external BEC during flight, 

the controller will perform a fast startup process and resume working very quickly after a reboot. Self-test 

and gyro calibration will be skipped in the fast start mode to avoid losing control of the aircraft. See P9 

“Brown-out Fast Recovery” for more details.
