Stick Control Modes 

A3X Pro E. 

provides  2  different  control  modes  for  the  sticks,  including  Manual  Mode  and  Automatic  Mode.  The 

default is Manual Mode when you first get it. 

Manual Mode (MM) 

When  manual  mode  is  chosen, the sticks  are  used to control  the  surfaces  directly  as  usual.  That  is,  there  is  no 

rotation rate or tilt angle locking and limitation when you move the sticks. All the servos will be completely under 

the control of the radio. It’s more obvious to the users because you can see the servos move following the sticks as 

you expected. The plane will maintain its original control behavior when operating it in this mode. 

Auto Mode (RR/AR) 

When  using  this  mode, the controller  will  take  over  the  control  of  all  servos.  The  sticks  are  used to control  the 

rotation rate (RR) on each axis when flying in normal or 3D mode, or the tilt angle rate (AR) on each axis when 

flying  in  auto-balance  or  auto-hover  mode.  The  max  rotation  rate  and  max  tilt  angle can  be  set  in the  program 

card  or  the  config  software.  In  this  mode,  the  controller  will  handle  the  position  of  the  surfaces  based  on  the 

actual  rotation  rate  or  tilt  angle  of  the  plane  intelligently.  This  is  why  the  movement  of  the  servo  will  become 

different from the manual mode.

:

 

Stick controls the servo directly.

 

RR

:

 

Stick controls the rotation rate on each axis.

 

AR

:

 

Stick controls the tilt angle rate on each axis.

 

 

Whatever  the  setting  of  control  mode  is,  the  stick  is  always  used  to  control  the  servo  directly  when 
operating in gyro off mode or the gyro of the corresponding axis has been disabled. 

 

Whatever the setting of control mode is, the stick is always used to control the rotation rate on each 
axis when operating in 3D mode.
