Features: This cable serves as the important connection between the flight arrange and power units, accurately delivering control commands to four ESCs for accurate brushless motor speed regulation, ensuring stable flight and fast response. Featuring a distinct multi branched star shape with flexible circuit board technology, this 8-10cm cable is engineered to fit the mainboard and arm interfaces seamlessly, making it incompatible with global cables or other variants. Weighing just 1-2 grams, it includes strengthened substance in key stress areas, adhering to strict weight limits while preserving robustness during continuous operations. Equipped with a main control board link and four separate motor interfaces, it utilizes dense BTB connectors for consistent power and data transfer in tight spaces. This specific replacement component requires concentrated tools like hot air equipment and microscopes, along with advanced soldering expertise, and is recommended to be dealt through licensed service channels.
