SIMON ESC 30A Electronic Speed Controller is specifically made for quadcopters and multi-rotors. Which provides faster and better motor speed control giving better flight performance compared to other available ESCs. Simon 30A BLDC ESC Electronic Speed Controller can drive motors which consume current up to 30A. It works on 2S-3S LiPo batteries. This electronic speed controller offers a battery eliminator circuit (BEC) that provides 5V and 2A to the receiver so we don’t need extra receiver battery. This version of the ESC also includes backwards-polarity protection and protection on the 5V receiver line, this means that if you accidentally attach a battery backward it won’t destroy your motor controller and other BECs won’t affect the ESC.
