LEVEL CALIBRATION

 

 

When  flying  in  Trainer  mode  or  Auto-Level  mode,  A3  Pro  needs  to  know  the  angle  of  the  plane  in  both  roll  and  pitch 

directions, this is achieved by calculating the attitude of its own. A small angle deviation caused by installation can lead to 

an  unexpected  behavior  when  flying  in  Trainer  mode  or  Auto-Level  mode.  For  this  reason,  a  level  calibration  is 

recommended  to  offset  the  error  caused  by  installation  and  to  establish  a  proper  level  reference  of  your  plane  after 

installing the gyro. 

 

Before calibrating, the plane should be placed on the horizontal ground and make the wing parallel to the ground. Make the 

plane slightly nose-up because a certain elevation angle is usually required to maintain level flight for most planes.   

 

Short press the button when LED is flashing 3 times in the Function Menu, then LED will start blink Blue rapidly for several 

seconds, don’t move the plane and keep its attitude until the calibration is done. 

 

 

 

7.4.

HOVER CALIBRATION

 

 

As a same reason, a hover calibration is recommended to perform after installation if you want to fly with Auto-Hover mode. 

The procedure is quite similar to that of level calibration. The only difference is in the first step. Before calibrating, you need 

to lift the plane and make it vertical to the ground instead of putting it on the ground.   

 

Short press the button when LED is flashing 4 times in the Function Menu, then LED will start blink Blue rapidly for several 

seconds, don’t move the plane and keep its attitude until the calibration is done.

SETUP MENU

 

 

The Setup Menu contains 7 setting functions which cover all parameters of the gyro you may need to setup. 

Entering the Setup Menu 

To get into the Setup Menu, press the button down and don’t release it until LED starts flashing White quickly. (FYA: Don’t 

release the button when LED turns solid White yet, or you will get into the Function Menu but not the Setup Menu.) 

 

 

Menu Selection 

In  the  Setup  Menu, LED  will flash White several  times  every  3 seconds  in  a  loop  and the  number  of  times  LED flashes 

shows at which function item you are currently. For example, one White flashing means the first setting “Wing Type”, after
