HWI30901001This will be drop shipped from our vendor!XRotor-40A Multirotor ESC Features: Special Core program for Multi-Rotor Controllers that 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.
