Yujian Line--Yujian8

Material: Utilizes T700 high-strength carbon plate with a fully carbon-fiber body, ensuring robustness and crash resistance. Design: The drone features aluminum alloy wiring ducts on the arms to protect motor wires. It offers a variety of personalized exterior coatings. Model Structure: DC-type. The arms are reinforced with additional strengthening ribs for enhanced stability. The camera is equipped with a high-strength protective component and integrated molded side panels. Constructed with 7075 aviation aluminum alloy, it is lightweight yet highly durable, and includes aluminum alloy heat sinks. Each arm is fitted with two optical fibers, and the bottom features illuminated "Tianjian" (or a specific brand logo, as "天剑" may refer to a brand name) logos that can light up, controllable via an app. It supports both analog and high-definition video transmission (compatible with O3/O4 video transmission systems). Parameter adjustment is performed via a Type-C interface externally located on the top. The entire device is waterproof. Note: "天剑logo" is directly translated as "Tianjian logo" here; if "天剑" is a specific brand name, it's better to retain its original form in English contexts where brand recognition is important. If a more generic translation is preferred, "Sky Sword" or another appropriate name could be considered based on branding strategy. In this translation, I've kept it as "Tianjian" for accuracy.
