F/W Version 2.1 

6.5.

 

Power Supply 

The controller is powered through the [BATT] pins. To achieve it, you can connect it directly to any idle channel 

of the receiver using the included 3-wire receiver cable, or to an independent BEC. The voltage range is 5 to 6V. 

If 

a  BEC  is  used  as  the  power  supply,  please  make  sure  that  the  voltage  not  exceeding  the  working  voltage 

permit of your servos, and verify that the BEC have sufficient capacity to provide working current for all 

the electronic devices on the aircraft especially when using several high torque servos.

 

6.6.

 

Flight Mode Channel (FMOD) 

  [FMOD] is used for switching the flight mode. We have assigned a 3-position switch to it as mentioned above. 

The expected flight mode can be preset in the function "Flight Mode" of the program card or config tool. System 

will  default  to  the  mode  which  assigned  to  position-1  if  you  leave  this  pin  unconnected.  Even  so,  it  is 

recommended  that  you  always  use  an 

independent  channel  to  switch  the 

mode in flight. 

 

6.7.

 

Master Gain Control Channel (GAIN) 

[GAIN] is used to control the master gain remotely. In this case, we use a knob (RD) to make a linear adjustment 

of  the  gain.  Surely  a  3-position  switch  can  be  used  instead  to  get  a  3-level  gain  control..  Once  connected,  the 

master  gain  will  be  controlled  by  the  transmitter  directly.  Only  when  the  pin  is  disabled  or  unconnected,  the 

master gain can be modified via the program card or config tool. 

6.8.

 

Dual Aileron & Elevator 

A true dual aileron and elevator system is available now on 

A3X Pro E.

, the OUT4 is for the 2nd aileron servo and 

the  OUT5  is  for  the  2nd  elevator  servo.  Mostly  we  use  two  aileron  servos  with  single  aileron  input,  in  this 

condition, you just need to plug the two aileron servos into OUT1 and OUT4 respectively. The OUT4 will become 

a  mirror  of OUT1 by the software automatically,  which  can avoid the  hassle using a Y-extension cable.  This is 

very similar in connecting the dual elevator. 

 

The  dual  channels  share  the  same  settings,  such  as  servo  limits,  gyro  direction  and  gain  setting  and  so  on.  For 

example, if you set the servo limits of aileron channel to 

±

80%, the maximum travel of both aileron servos will 

be 

±

80%. 

6.9.

 

Wing Type & Mixing 

A3X Pro E.

 has already built in such mixing functions as delta-wing (flying-wing) and v-tail. When operating it in 

such modes, the corresponding mixing must be disabled within your transmitter. 

All you need is to set your radio 

to a single 4-channel fixed-wing mode

. Connect the servos by following the illustration shown.
