Hobbywing XRotor 40A APAC Brushless ESC 2-6S For RC Multicopters Hobbywing XRotor-40A APAC Brushless ESC 2-6S For RC Multicopters Specification: Brand:Hobbywing Model Number:XRotor-40A Cont.Current:40A Burst Current(10sec):60A BEC:None Lipo:2-6S Programming:Timing(high/middle) Size:68x25x8.7mm Plug:¦µ3.5mmx3 Usage:RC Multicopter APAC means Asia-Pacific Version,the official ESC sold in Asia-Pacific areas. Features: Using Multicopter special program, fast throttle response,surpasses all kinds of open source software; Firmware was optimized specifically for disc motor, and it has a very good compatibility; Highly intelligent, strong adaptive capacity, reserve the timing setting item (height/middle timing), easy to use; Throttle signal line is twisted wire to reduce crosstalk within the transmission signal generated by the copper, so that more stable flight; Supports refresh rates up to 621Hz throttle signal, compatible with various flight controllers. (Note: the throttle signal over 500Hz are all non-standard throttle signal); Using MOSFET special driver IC, its performance and stability far surpass the driving circuit with discrete components built; Ultra-low resistance MOSFET, strong flow capacity. Package Included: 1x Hobbywing XRotor 40A brushless ESC
