BLHeli 20A ESC for FPV Racing Drone

Features: brand new and high quality The ESC firmware is BLHELI 14.2 version, but it can be connected through the signal line to flash the firmware to adjust the parameters. It is specially designed for the mini multi-rotor traversing aircraft, and the throttle response speed is fast. Energy-saving design, with good compatibility with common motors; Throttle signal adopts twisted pair cable to reduce crosstalk and more stable signal transmission in flight. Throttle refresh rate, for all flight control systems. Using the new process ultra-low resistance miniature MOSFET, it has the characteristics of high-speed and high-load conductivity.
