Optimized for FPV Racing: The Borg 5S RX Stack is designed to enhance your FPV racing experience. It includes a high-performance Borg 5S RX FC flight controller and a powerful Borg 60R ESC to top responsiveness and durability. Onboard ELRS 2.4GHz receiver, supports wide voltage input (4-8S). Onboard 2.4GHz antenna, switch between internal or external.antennas by shorting the pad, providing flexible options. Meet the need for better reception signal under different flight environment conditions. Onboard anti-spark module and (transient voltage suppressor) dual protection to avoid voltage spikes. Onboard polymer capacitor, 5-inch racing models can fly without external capacitors, simplifying the installation process and reducing the overall weight of the aircraft.
