Plug  the  USB  adapter  to  the  DATA  PORT  of  ZYX-S2,  and  then  connect  to  PC.  Open  ZYX 

Assistant1.0.exe, the interface of this program is in the following figure. 

 

 

Disconnect the ESC and motor, turn on the transmitter, power on the helicopter and ZYX-S2. Select 

COM port in the software, and click 

“Connect”. The status bar should show “Download Parameters 

Completely

”, this means ZYX-S2 has been connected to the software successfully. Click “Setup”, and 

setup your helicopter step by step. 

Notice:

 The parameters in 

”Advanced” menu do not need to be changed generally, “Basic” menu is 

enough for 3D flight.   

If you are a experienced pilot, you can adjust 

”Advanced” menu to obtain the desired feeling. 

7. Check before first flight 

Disconnect  the  ESC  and  motor,  power  on  the  transmitter  and  the  helicopter,  move  all  the  stick 

to check the servo direction. 

Pick up helicopter and rotate it around its 3 axis, check the Gyro Compensation Direction.
