Connection to a BEC is optional. For models of 500 size and larger it is recommended to use dual power supply cables due to the increased power consumption. That means besides the S-BUS cable, an additional power supply cable should be connected to the AUX port.
連接到BEC是可選的。 對於500型及以上型號，我們強烈建議使用雙電源電綫，因為功耗增加。 這意味著除了連接S-BUS電綫外，還應連接一個額外的電源線到AUX端口。
