Simonk 30A BLDC ESC 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. Simonk 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 no extra receiver battery is required. This version of the ESC also includes backward-polarity protection and protection on the 5V receiver line, this means that if you accidentally attach a battery backward it wont destroy your motor controller and other BECs wont affect the ESC. Warning:In case the BLDC ESC is connected directly to the remote control receiver, never ever switch off the remote control before switching off power to the BLDC ESC. Depending on the model of the remote control, it may result in full throttle applied to the motor and it will rotate at full speed. Features: High-quality MOSFETs for BLDC motor drive High-performance microcontroller for best compatibility with all types of motors at greater efficiency Fully programmable with any standard RC remote control Heat sink with high-performance heat transmission membrane for better thermal management 3 start modes: Normal / Soft / Super-Soft, compatible with fixed-wing aircraft and helicopters Throttle range can be configured to be compatible with any remote control available in the market.
