If it exceeds 5V, the built-in amplifier and microcontroller will be burned. If the BEC of the electric adjustment is 6V, it is recommended to connect 2 2A in series The rectifier diode removes power from the receiver, and the voltage drop is 1.2-1.4V, which supplies power to the sound group.
- Control method:After the control is turned on, when the throttle channel moves for the first time, the engine sound will automatically start. If the engine idles for more than 20 seconds, the engine sound will automatically turn o
