Page 2 DSMJ、DSM2、DSMX receiver(Requires optional adapter cable): Connect the tail servo to CH4 and connect swashplate servos to CH1, CH2, CH3 according to the type of the swashplate.
Page 3 4. Gyro mounting ZYX-S2 should be mounted to a steady platform which is perpendicular to the main shaft and far away from the engine and other electric devices. ZYX-S2 has good vibration resistance, mounting on a conventional electric or fuel helicopter by a 1mm foam pad only.
Page 4 Notice: Don’t connect servos to the gyro until finishing the servo type configuration. 6. PC software installation and setup Notice: If you use ZYX-S2 for the first time, you must connect ZYX-S2 to PC software, and setup your helicopter. If you don’t do this, may put your servos and helicopter at risk! PC Software download address: www.0577mx.com...
Page 5 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”.

Page 7 Decrease the total gain of main rotor. Red LED is flashing fast Intermittently ZYX-S2 detects the minimum supply voltage is lower than 3.8V, replace the gyro power supply module or check whether there is servo stuck phenomenon. Yellow LED is flashing slowly Error occur during RC signal Initialization, please check the receiver option and wires, keep the sticks centered, restart the gyro.
