In pursuit of his “dream of the blue sky,” Chen Ruihua, a resident of Qianqun, Changshu, spent a year and invested tens of thousands of yuan to build a rotorcraft with his own hands. Although the aircraft is rudimentary, its flight capabilities are impressive. However, during a recent “test flight,” local police promptly intervened and advised him against it. The police pointed out that flying vehicles must comply with legal regulations.
Yesterday morning, a reporter contacted Chen Ruihua, who shared that he has loved model aircraft since childhood and has always dreamed of building his own plane. Chen Ruihua stated, “This rotorcraft may look a bit crude, but it is fully functional. It is modeled after a certain type of Russian rotorcraft, with an engine sourced from a second-hand motorboat. The main structure is made of aluminum alloy, and the parts were purchased from online platforms or hardware stores, with some custom-made by processing factories according to my designs.”

To realize his “dream of the blue sky,” Chen Ruihua dedicated himself to studying a large number of aviation theory books, gradually learning about design, drawing, motors, welding, and more. He also engaged in technical exchanges with many model aircraft enthusiasts across the country through online platforms. To build the aircraft of his dreams, he invested considerable funds. After a year and two failed attempts, the current version of his “rotorcraft” is already the third generation, weighing over 170 kilograms, measuring 3.5 meters in length, capable of flying hundreds of meters high, and its body can be folded.

Chen Ruihua filmed the “test flight” process and posted it on his personal social media platform, garnering praise from many netizens, which also caught the attention of the Qianqun police station. Upon investigation, it was found that Chen did not possess a relevant flight license, and blind test flights could pose a threat to his safety and that of nearby residents, as well as hinder the management of air traffic control. After multiple discussions, Chen promised not to conduct further test flights. “The spirit of hard work and research shown by Master Chen is commendable, but from a public safety perspective, it is essential to comply with laws and regulations,” said Gong Jian, a police officer from the Qianqun police station.
It is understood that China has strict regulations regarding flying activities. On June 1, 2004, the Civil Aviation Administration of China implemented Order No. 120, which governs general operations and flight rules. For private ultralight aircraft weighing less than 116 kilograms, only compliance with regulations is required, and no approval is necessary. However, regardless of the aircraft, an airspace application must be submitted before each takeoff. Additionally, according to relevant ultralight aircraft flight rules, if powered, the aircraft must meet the following conditions: an empty weight of less than 116 kilograms; a fuel capacity not exceeding 20 liters; and a calibrated airspeed of less than 100 kilometers per hour during level flight. Exceeding these conditions requires the pilot to hold a “license.”
