Features: Super Small & Light ESCs with incredible small size and light weight are specially designed for competition FPV drones. Quality Components The use of F396 48MHz MCU, imported MOSFETs (Toshiba MOSFETs for 20A ESCs) and ceramic capacitors 3-in-1 drive ICs, 3-ounce copper, 4 layers of PCBs and other quality components guarantees less heat, higher efficiency and rapider response BLHeli Firmware Ready Users can flash or upgrade the BLHeli firmware via the signal cable (on ESCs), and program 4 ESCs simultaneously after connecting their flight controller to the BLHeliSuite software if the flight controller uses the CleanFlight firmware. Damped Light Mode & OneShot125 Mode Supported Damped light mode improves the motor retardation and allows users to brake the FPV drones more efficiently. Active-freewheeling technology improves driving efficiency, flight time and heat dissipation. The ESCs support OneShot125 high speed throttle signal and regular throttle signal (within 500Hz) modes Twisted-Pair Signal Cable Reduces Interference The twisted-pair throttle signal cable effectively reduces interference produced in signal transmission and makes the flight much more stable and reliable.
