80x45 Drone Propeller

80x45 Composite Plastic Drone Propeller

The 8045 Composite Plastic Drone Propeller is a two-bladed propeller model developed for hobby drones, training multicopters, university UAV projects, and light-mission platforms. With an 8-inch diameter and 4.5-inch pitch, it offers a balanced performance between lift, energy consumption, and flight control.

Available with CW and CCW rotation options, the 8045 propeller can be used on F450 and F550 class airframes, APM or Pixhawk-based training drones, and custom-built multicopter projects. Its lightweight construction, low-vibration operation, and wide motor compatibility make it an ideal choice for beginner and development projects.

In the 8045 propeller code, the first two digits indicate the diameter of the propeller, and the last two digits indicate the pitch:

8-inch diameter: Approximately 203.2 mm
4.5-inch pitch: Approximately 114.3 mm
Number of blades: 2 blades
Rotation direction: CW and CCW
Usage class: Light and medium-class multicopters
The 8-inch diameter helps create sufficient lift in compact drone platforms. The 4.5-inch pitch provides stable acceleration, controlled maneuvering, and efficient energy consumption.

With these features, 8045 propellers are preferred in applications requiring stable and economical flight rather than high speed or heavy loads.

Drone Models and Platforms in which it is used
The 8045 drone propeller can be used in various quadcopter, hexacopter, and custom-built UAV projects, provided the motor and mounting system are compatible.

Main application areas:

Multicopters in the 450–550 mm class
Custom-built bodies similar to the DJI F450
F550 class hexacopter platforms
APM-based training drones
Pixhawk flight-controlled multicopters
University UAV and robotics projects
Entry-level FPV platforms
Lightweight mapping and imaging drones
Agricultural technology prototypes
Do-it-yourself (DIY) drone projects
Lightweight camera-carrying quadcopters
Training and testing unmanned aerial vehicles
The 8045 propeller is not designed for heavy-duty professional agricultural drones or large industrial UAV systems. Larger diameter and higher load-carrying propellers should be preferred for such applications.

Technical dimensions may vary depending on the production series and hub connection design. Motor shaft and center hole dimensions should be checked before assembly.

Compatible Motor Classes
The 8045 two-blade propeller is mostly used with the following brushless motor classes:

A2212 920 KV
A2212 1000 KV
A2212 1400 KV
2216 880 KV
2216 920 KV
2216 1000 KV
Motor compatibility should not be determined solely by the model code. The motor's operating voltage, the propeller size recommended by the manufacturer, the maximum current rating, and the ESC capacity should be considered together.

Especially when using the 8045 propeller with higher speed motors such as 1400 KV, battery voltage and current consumption should be carefully monitored. The wrong combination may cause the motor or ESC to overheat.

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

A2212 920 KV and 3S LiPo: Approximately 700–850 g
A2212 1000 KV and 3S LiPo: Approximately 800–900 g
2216 920 KV and suitable 4S system: Approximately 900–1100 g
These values ​​are not a guarantee of consistent performance. Actual thrust may vary depending on motor brand, ESC settings, battery status, air temperature, altitude, propeller geometry and test conditions.

Advantages of the 8045 Propeller
The reasons for choosing the 8045 composite plastic drone propeller are:

Lightweight and balanced structure
Controlled energy consumption
Suitable flight characteristics for training drones
Wing design that supports low vibration
Aerodynamic structure that helps quiet operation
Wide compatibility with different motors
CW and CCW rotation options
Easy assembly and replacement
Suitable for hobby and university projects
Cost-effective replacement propeller solution
Use on F450 and F550 class platforms
Balanced lift for lightweight camera systems
Glass fiber reinforced composite plastic models can offer a more rigid wing structure compared to standard ABS propellers. Controlled flexibility helps reduce the risk of breakage in minor impacts.
