The “1238 HD Glass Fiber Nylon Propellers 1CW+1CCW (1 Pair) – Gray” refers to a pair of propellers, one for clockwise (CW) rotation and one for counterclockwise (CCW) rotation, which are typically used to ensure balanced operation of a drone or quadcopter. The “1238” in the name indicates the size of the propellers, with “12” representing the length in inches and “38” indicating the pitch in inches. The “HD” suggests that these propellers are designed for high-definition drones. The material composition includes glass fibre and nylon, which offers a balance of strength and flexibility. The gray color is a visual description.

The HD Propellers 1238(12X3.8) Glass Fiber Nylon Gray is the high-quality propellers specially designed for multi-copters.
These Propellers are light in weight and high strength propeller has a 15° angle design at the end of the propeller to avoid whirlpool while the multi-copter is flying. They are useful in drones as well as in multi-copters.

Features:
Here are some common features associated with these propellers:

Material Composition: These propellers are made from a combination of glass fiber and nylon. This material mix provides a balance of strength and flexibility, making them durable and suitable for withstanding the demands of flight and potential impacts.

Color: Described as “Gray Propellers,” indicating their color.

Size: The “1238” size indicates the length and pitch of the propellers. In this case, they are 12 inches long with a 3.8-inch pitch.

Clockwise (CW) and Counter-Clockwise (CCW) Rotation: The package includes one propeller for clockwise (CW) rotation and one for counter-clockwise (CCW) rotation. This is crucial for ensuring balanced and stable drone operation.

Balanced Performance: Well-designed propellers should provide balanced performance, including stability, efficiency, and responsiveness during flight.

Easy Installation: These propellers are typically designed for easy installation and replacement on compatible drone or quadcopter models.

Compatibility: Ensure that these propellers are compatible with your specific drone or quadcopter model, as compatibility can vary depending on the manufacturer.

Performance Optimization: These propellers may be optimized for specific performance characteristics such as lift, thrust, or efficiency, making them suitable for particular types of drones or applications.
