A micro drone weighing less than a cup of milk tea, how fast can it fly? Xu Yang, a junior student from Shenzhen University, provided a shocking answer: 340.78 km/h!The “Prowess” quadcopter developed by Xu Yang recently received Guinness World Record certification, breaking all speed records in the field of model aircraft, and becoming the first record created by a Chinese.

The motors and propellers are the core power components. The propeller is made using 3D printing technology, and the body is painted in fluorescent red, giving it a sporty and fierce look.
Speed Comparable to High-Speed Rail
Micro Drone “Prowess”
Breaking Physical Limits
The “little gadget” introduced by Xu Yang is a flying device named “Prowess”. Weighing only 247 grams, it achieves an incredible speed of 340.78 km/h, nearly reaching the design speed of China’s high-speed rail at 350 km/h. Under the witness of a Guinness certification officer, this flying device performed stably within a 50-meter speed measurement zone, ultimately setting a new world record.

Compared to other competitors, my advantage lies in reducing the structure’s weight to the minimum, distributing all the weight to the motors and battery power. The most important point is that I used my own designed 3D printed high-speed propeller, which can achieve much higher speeds than commercially available propellers.
Seemingly Effortless
Filled with Difficulties and Challenges
Although Xu Yang describes his R&D process with ease, behind the seemingly effortless breaking of the world record, he faced numerous difficulties and challenges.

The main difficulties were technical challenges. The entire design process of the drone is a systematic engineering project. For example, the aerodynamic design of the propeller, my experience was not particularly rich, so I had to consult many industry experts to help optimize my design.
Strong Interest in Model Aircraft Since Childhood
In the fourth and fifth grades of elementary school, Xu Yang saw model aircraft enthusiasts playing with their remote-controlled models in Futian Central Park, which sparked his strong interest in model aircraft. During his university years, he remained active at the forefront of model aircraft and focused on micro quadcopters.
This category of flying devices is relatively niche in the model aircraft community, but its extreme lightweight and power efficiency optimization design challenges give it significant potential in the drone field.
Currently, Xu Yang is working in Professor Jin Yuhua’s research group at The Chinese University of Hong Kong (Shenzhen), focusing on a project researching balloon-floating robots. This robot can perform AI interactions and move autonomously. Xu Yang also stated that he will continue to delve into the drone industry and choose a suitable development direction for himself.
