Features: The power output component (MOSFET) adopts a new generation of manufacturing process, which has low heat generation, high instantaneous current and high reliability. Smaller MOSFETs minimize weight. Supports the high-speed brushless motors that are currently in the market for most industrial production. The SBEC circuit chip uses a high-power synchronous rectification scheme with strong rudder capability. The chip has overheat protection, overload protection, overcurrent protection, low voltage protection and remote signal loss protection. Multi-speed motor starting force, adjustable motor advance angle, can achieve perfect starting effect. Safe power-on function: When the power is turned on, the remote control's throttle lever will not start the motor at any position, preventing the motor from rotating suddenly. Over-temperature protection, when the ESC temperature exceeds 110 °C, the output power is automatically reduced. When the temperature is lower than 110 °C, the power output is restored. Extremely low internal resistance, ultra-smooth and precise throttle linearity. It can be programmed with straight tube, simple LCD, jumper cap and PC interface. ESC software can be upgraded for PCs. Lightweight, compact, and the perfect small size ESC for racing.
