The Hobbywing XRotor 10 Amp Mini Multi-Rotor Brushless ESC is a great choice for 250 class FPV drones. With quadcopter optimized software and programmable timing, this easy to use ESC provides stable flight characteristics that make it perfect for custom builds. Features: Special core program for multi-rotor controllers greatly improves throttle response. Specially optimized software for excellent compatibility with disc-type motors. All settings except the timing are preset, making usage simple, highly intelligent and adaptive. The twisted-pair design of the throttle signal cable effectively reduces the crosstalk produced in signal transmission and makes flight more stable. Compatible with various flight-control systems and supports a signal frequency of up to 621Hz (Note: all throttle signals over 500Hz are non-standard signals). Special drive chip has much better MOSFET driving effect than common driving circuit consisted of discrete components. MOSFET with extra-low resistance brings high performance and great current endurance.Specifications: Model: XRotor-10A-Mini-3S Typical Applications: 250 Class Quadcopter Continuous Current: 10A Peak Current （10s）: 15A BEC: No LiPo: 2-3S Weight: 7g Size: 44.2x12.2x9.2mm
