8pair Gemfan Hurricane 3520 Propeller 3.5X2X3 3-Blade Props for 3.5 Inch Quad with 1.5mm 3 Holes 1806-2004 Brushless Motor RC FPV Racing Drone Parts DIY
Product Description
Gemfan Hurricane 3520 Propeller Set
The Gemfan Hurricane 3520 propeller set comes in a quantity of eight pieces. Each propeller measures 3.5 inches in diameter and has a 2-inch pitch. The design includes three blades that are engineered to fit 3.5-inch quadrotor configurations. The motor mount on each propeller uses a 1.5 millimeter spacing with a three‑hole pattern, allowing secure attachment to compatible brushless motors.
Key Dimensions and Specifications
- Diameter: 3.5 inches
- Pitch: 2 inches
- Blade count: 3
- Motor mount: 1.5 mm, 3 holes
- Quantity: 8 individual propellers
These dimensions are consistent with the standard sizing for 3.5-inch quadcopter builds. The pitch and diameter values are expressed in common metric and imperial units that are used in the RC and FPV communities. The three‑blade configuration is a typical choice for hobbyists who require a balance between lift and agility in small racing drones.
Design Considerations
The Hurricane 3520 series is designed to accommodate brushless motors with model numbers ranging from 1806 to 2004. The 1.5 millimeter hole spacing matches the motor shaft and mounting flange that are found on these motors. The three-hole pattern on the propeller hub provides a secure connection that helps maintain rotational stability during flight. The blades themselves are formed to produce the necessary lift for a 3.5-inch quad configuration while keeping rotational drag within acceptable limits for hobby‑grade aircraft.
Compatibility and Use Cases
These propellers are intended for use on RC FPV racing drones and other small quadrotor platforms that employ 3.5-inch brushless motors. The 1806-2004 motor compatibility indicates that the propeller set is suitable for a range of power outputs commonly seen in DIY racing builds. Hobbyists and developers who construct or modify quadrotor systems can select this set when a 3.5-inch, 3-blade propeller is required.
Application Process
Installing the propellers involves mounting the hub to the motor shaft using the 1.5 millimeter spacing. The three holes in the propeller hub align with the motor’s mounting plate, providing a stable attachment. Once the propellers are secured, the quadrotor’s flight controller and electronic speed controller can be configured to match the new hardware. Users who are familiar with DIY drone assembly will find that the Hurricane 3520 set integrates with standard 3.5-inch quads without requiring additional adapters.
Construction and Materials
While the product description does not specify material composition, the propellers are manufactured to match industry standards for hobby-grade RC components. The design emphasizes a lightweight build that balances performance with ease of handling during assembly and maintenance. The three‑blade structure provides a compact shape that is useful in small frames where space and weight constraints are important.
Assembly and Maintenance Tips
During installation, it is advisable to double‑check the alignment of the motor mount holes to ensure a secure fit. Because the propellers are designed for 3.5-inch quadrotor platforms, they should be used only on compatible frames to avoid imbalances. Regular inspection of blade edges can help detect any wear or damage that might affect flight dynamics. Replacing the entire set after a single incident of blade damage helps maintain consistent performance across the quadrotor.
Overall Description
This product delivers an eight-piece supply of Gemfan Hurricane 3520 propellers, each measuring 3.5 inches in diameter and featuring a 2-inch pitch. The three-blade configuration is tailored to fit 3.5-inch quadrotor systems. The 1.5 millimeter, three-hole motor mount allows attachment to brushless motors ranging from 1806 to 2004. Designed for RC FPV racing drones and DIY builders, the set provides a standardized set of propellers that can be swapped or upgraded on compatible quadrotor platforms. The packaging contains eight individual propellers that can be installed quickly by following standard mounting procedures.
