RIY 9x5x3 Propellers for Drones

RIY 9x5x3 propellers are professional-grade three-blade airfoils designed to provide stable aerodynamics and maximum control during flight. They have a diameter of 9 inches and a pitch of 5 inches, which provides an optimal lift-to-efficiency ratio for medium and heavy payloads. Manufacturer: RIY, made in Ukraine, these propellers have been tested in combat conditions, confirming their reliability and durability in demanding operational scenarios.

Material and Construction
The blades are made of polyamide, reinforced with 40% fiberglass, which increases flexural strength and impact resistance while maintaining flexibility and the ability to regain shape after stress. This combination of materials ensures a long service life during intensive flights and minimizes the risk of damage upon contact with obstacles.

Hub Body and Compatibility
The hub has a diameter of 18 mm and a thickness of 9 mm, designed for an M5 shaft, ensuring secure attachment to standard motors and quick replacement during maintenance. The low weight of each propeller — 18.5 g — allows for an optimal balance between endurance and performance without increasing rotor inertia.

Package Contents
The set includes four propellers, in a convenient kit for quick installation:

• 2 x RIY 9x5x3 CW propellers
• 2 x RIY 9x5x3 CCW propellers

These propellers are suitable for various applications — from aerial photography and inspection missions to operational tasks in professional environments. Thanks to their three-blade design, RIY 9x5x3 propellers provide smoother lift and reduced vibrations compared to two-blade counterparts, which is especially important when shooting high-definition video or when high platform stability is required. Installation is simple: compatibility with an 18 mm diameter hub and an M5 shaft allows for quick propeller replacement in the field, and the CW/CCW set ensures balanced rotational operation of all drone motors.

By choosing RIY 9x5x3 Propellers, you get a durable construction made of reinforced polyamide, proven in demanding conditions, optimal geometric characteristics for efficient lift, and a complete kit for installation on standard motors with an M5 shaft.
