Dustproof and waterproof IP54, with splashproof function, it is forbidden to put it into water or use it underwater! CNC Full aluminum cover wrapped, enlarge the radiating , rapid heat dissipation, more stable work. High-quality and large-size MOSFETs are , with low internal resistance and low heat generation, plus CNC heat dissipation aluminum cover,Even if the throttle is used for a long time, it is not afraid of overheating, which brings more stable power performance. No welding, more peace of mind. With this FC, HD Air unit, analog camera, GPS and other common peripherals all support direct plug-in. Integrated dual BEC, support for O3 Air Unit air unit direct connection. The FC supports up to 8 motor outputs, easily build your X8 drone. Quickly check the working status of the FC by turning on and off the corresponding status indicator light.
