How to set the 30 amp sound of the new model airplane?

The commonly used setting for electronic control of New Star 30a is throttle setting. First connect the equipment, then turn on the remote control switch, push the throttle down to the maximum, then turn on the aircraft power supply (everything is based on good frequency, it is best to put the throttle fine adjustment in the middle position), then you will hear a beep, and then quickly pull the throttle to the lowest, with some beeps. ...........................................................
