1. The H743 is a 3-6S 36x36mm mini flight controller with a 128MB flash memory, 5V 10V dual BEC. Designed for easy maintenance and low interference. 2. The PCB adopts high-end composite material, which has stronger overcurrent capability and good heat dissipation. MOS adopts high current resistance mos, low energy consumption, and strong load capacity. 3. Using industrial grade , high temperature resistance. High-quality capacitors, strong filtering performance. 4. Intelligent control: The controller has a built-in low-noise button, which can be controlled remotely by one button. 5. Maximum power: The OSD allows you to control your drone with maximum speed and accuracy, while providing a smoother flight.
