Select your wing type, see Page 10. 

 

Mounting 

Select the mouting orientation of the controller, see Page 5. 

 

Gain 

This tab is used to setup the gain for each flight mode. The gain is affected by many factors there is no standard 

answer to that how much it should be. You need to fine-tune to get the best result. The plane will be oscillating in 

the corresponding direction if the gain is set too high, this is a result of over amplification of the gyros, this rapid 

back and forth movement can make the plane hard to control. But if the gain is too low, the plane will likely to be 

hard to control. We suggest you start your first flight with a lower gain setting and then increase them gradually. 

You can also use the remote master gain channel to get a more convenient way to adjust the gain when in a flight. 

 

  Gain  Rate 

  In  order  to meet  more  needs, 

A3X Pro E.

  provides  3-level  (Small,  Medium  and Large)  gain  level  for 

each flight mode. You can choose a larger level when the current gain is still not large enough, even when it has 

been set to the maximum. However it is recommended to use as small level as possible to improve the precision 

of gain adjustment. 

 

  VERY IMPORTANT! 

1

 

A3X Pro E. 

is  aimed  at  all  types  of  fixed-wing  airplanes.  Usually  the  default  gain  settings  are  ready  to  go. 

However, sometimes you still have to adjust the settings manually according to your plane to get the best   

flying experience. 

2

 

To get the best performance in auto-hover mode, try to use the maximum gain for auto-hover mode. 

3

 

Please note that when the stick control mode is set to Auto Mode, you cannot set the gain to 0% or a very 

small volumn, or you will lost control of your plane!   

 

 

Radio 

All parameters related to the radio system can be setup within this tab. 

  Control Mode 

  Choose the stick control mode, see Page 9. 

  Receiver Type 

  Choose the receiver type, remember to reboot the controller after change the type.
