90x45 Drone Propeller

90x45 Composite Plastic Drone Propeller

The 9045 Composite Plastic Drone Propeller is a two-bladed propeller model designed for mid-range multicopters, training drones, mapping UAVs, and custom-built aircraft projects. With a 9-inch diameter and 4.5-inch pitch, it offers a balanced performance between lift, flight stability, and energy consumption.

Available in both CW and CCW rotation directions, the 9045 propeller can be used on F450 and F550 class airframes, Pixhawk or ArduPilot-based multicopters, university UAV projects, and light agricultural prototypes. Its high-strength composite plastic construction supports low-vibration and controlled flight performance.

The numbers in the 9045 product code represent the basic dimensions of the propeller:

9 inches: Total diameter of the propeller.
4.5 inches: Pitch.
Number of blades: Two or three blades depending on the model.
Rotation direction: CW and CCW options are available.
A 9-inch diameter corresponds to approximately 228.6 millimeters. A 4.5-inch pitch helps the propeller create a balanced airflow. This size is preferred in mid-range drone systems that aim for controlled lift and efficient flight time rather than high speed.

Drones and Platforms it is Used In
The 9045 drone propeller can be used in various multicopter and UAV projects, provided the motor and hub connections are compatible.

Main application areas:

Quadcopters in the 450–600 mm class
Custom-built drone bodies similar to the F450
Hexacopter systems in the F550 class
Pixhawk flight-controlled multicopters
ArduPilot-based UAV projects
University and R&D drones
Mapping and photogrammetry systems
Lightweight camera-carrying imaging drones
Agricultural technology prototypes
Training and testing aircraft
Do-it-yourself – DIY multicopter projects
Lightweight industrial reconnaissance drones
The 9045 propeller is not designed for large, heavy-duty agricultural drones. The total takeoff weight of the platform and the thrust required per motor must be calculated in advance.

Technical values ​​may vary depending on the number of blades, manufacturing material, and hub design of the product.

Compatible Motor Classes
The 9045 two-bladed drone propeller is generally used with brushless motors with low to medium KV values.

Common motor options:

A2216 880 KV
A2216 920 KV
2218 810 KV
2814 700–900 KV
Brushless motors with similar power and torque values
Motor compatibility should not be determined solely by body size or KV rating. The propeller chart recommended by the motor manufacturer, battery voltage, maximum current, and ESC capacity should be considered together.

Approximate Thrust Performance
The approximate thrust values ​​that can be obtained depending on the motor and battery combination are as follows:

A2216 880 KV and 3S LiPo: Approximately 900–1,050 g
A2216 920 KV and suitable 4S system: Approximately 1,000–1,200 g
2814 800 KV and suitable 4S system: Approximately 1,200–1,500 g
These values ​​are estimates and do not guarantee consistent performance. Actual thrust can vary depending on the motor brand, battery status, ESC settings, air temperature, altitude, and propeller blade geometry.

Advantages of the 9045 Propeller
The prominent advantages of the 9045 composite plastic drone propeller are:

Strong lift performance in mid-range drones
Stable and controlled flight characteristics
Efficient energy use
Wing structure supporting long flight times
Stable operation in camera-carrying drones
Supports low-vibration operation
CW and CCW rotation options
Wide motor compatibility
Lightweight and durable composite plastic structure
Suitable for educational and university projects
Easy assembly and replacement
Domestic production and easy supply advantage
The glass fiber reinforced composite plastic structure can provide a more rigid blade geometry compared to standard plastic propellers. Controlled flexibility can help reduce damage from minor contact and impacts.
