iFlight Borg 60 is a high-performance ESC that can handle currents up to 60A. It uses BlHeli_32 firmware with support for bidirectional DShot and variable PWM frequency. A notable feature is the integrated anti-spark filter, which prevents sparking when connecting the battery to the quadcopter. The ESC uses polymer capacitors and eliminates the need for an external electrolytic capacitor, making the final build smaller and lighter.
