In late August 2025, RAYI Propeller, a provider of drone propeller solutions, hereinafter referred to as (RAYI), participated in the Kazan International Drone Exhibition in Russia, presenting its full range of 

self - developed multi - rotor and fixed - wing propeller product matrix.

Hard - core Technology Cluster

RAYI brought three core product lines to the exhibition, namely carbon fiber multi - rotor propellers, carbon fiber fixed - wing propellers, and carbon fiber general aviation propellers. The company offers 

carbon fiber propellers ranging from 12 to 98 inches, which are characterized by ultra - light weight, high strength, high efficiency, and high cost - effectiveness. These features have won wide popularity 

in the domestic and international drone industries.

Core product series: KE (carbon fiber multi rotor propeller), DK (electric fixed wing propeller), YK (oil driven fixed wing propeller)

The newly developed IIKE series of carbon fiber propellers became the focus of the exhibition. Using the company's exclusive self - developed molding process, these propellers are 30% lighter than 

traditional propellers and 7% more efficient. In the actual test of multi - rotor drones, the single 72 - inch carbon fiber integrated propeller can achieve a maximum pulling force of 180 kg. The efficiency 

has been improved by 7% compared to previous products and 15% compared to the original blades. Moreover, there is a significant reduction in noise levels.
