Director of Product Development, Haze Flight
Guinness World Records Title Holder
Lead Engineer Behind the World's Fastest Sub-250g RC Micro Quadcopter

Officially certified at 358.36 km/h (222.67 mph) — a new world benchmark in high-speed micro drone engineering.
Pok Yao serves as Director of Product Development at Haze Flight, where he leads the company's research, engineering, and product innovation across its next generation of FPV systems and high-performance UAV technologies. Responsible for the entire product development lifecycle—from concept and system architecture to engineering validation and production—he drives the creation of technologies that combine exceptional performance, reliability, and user experience.
Widely recognized for his engineering achievements, Pok is the Guinness World Records title holder for the Fastest Ground Speed by a Remote-Controlled (RC) Micro Quadcopter, reaching an officially certified speed of 358.36 km/h (222.67 mph) with a custom-designed aircraft weighing less than 250 grams. The accomplishment established a new world benchmark in high-speed micro drone engineering and demonstrated what is possible through advanced design, precision engineering, and relentless innovation.

A Complete Redesign, Built Around One Objective.
As the lead engineer responsible for the aircraft's structural architecture and aerodynamic development, Pok directed the complete redesign of the record-setting platform. Every component—from the carbon-fiber airframe and weight distribution to the aerodynamic profile and power system—was engineered around a single objective: maximizing speed without compromising stability or reliability under the strict sub-250g weight limit.
The project represented a comprehensive engineering challenge rather than a simple performance upgrade. Through six complete design iterations, extensive simulation, structural optimization, and countless hours of real-world flight testing, Pok and his team refined every aspect of the aircraft to achieve record-breaking performance. The final result closely matched pre-flight engineering predictions, highlighting the precision and maturity of the team's development process.
The success of the project also reflects Pok's engineering philosophy: innovation is achieved through systematic thinking, rigorous validation, and continuous iteration. By integrating computational analysis with practical testing, he approaches product development as a balance of performance, manufacturability, durability, and user experience—principles that continue to guide Haze Flight's engineering culture today.
Innovation, shared openly.
Beyond setting a world record, Pok is committed to advancing the global FPV community through open collaboration. Following the successful Guinness World Records certification, the complete aircraft design was released as an open-source project, allowing engineers, developers, and FPV pilots worldwide to study, improve, and build upon the platform. This commitment to knowledge sharing has earned widespread recognition throughout the international drone community and reflects Haze Flight's belief that meaningful innovation grows through collaboration.
At Haze Flight, Pok leads multidisciplinary engineering teams in the development of next-generation FPV products for enthusiasts, professional creators, and industrial applications. His expertise spans aerodynamic optimization, lightweight composite structures, propulsion system integration, flight dynamics, and high-performance product engineering, enabling the company to transform advanced research into products trusted by pilots around the world.
Under Pok's technical leadership, Haze Flight continues to redefine the limits of compact UAV performance. While breaking world records represents a significant milestone, his broader vision is to develop technologies that make high-performance flight more accessible, inspire the next generation of innovators, and shape the future of the global FPV industry.
