## Summary description

Two-blade propeller set by GRAUPNER for multicopter applications, size 8 x 4.5" (20.3 x 11.4 cm), model 2947.8X4,5. Designed for replacement or upgrade of multicopter rotor blades, this set provides the specified diameter and pitch for matching motor and airframe setups. Suitable for hobby and light-commercial multirotor UAVs where this size and blade count are required.

## Long description

Two-blade propeller set by GRAUPNER in size 8 x 4.5" (20.3 x 11.4 cm) designed for multicopter applications. This pair of rigid, shaped blades matches standard mounting dimensions for many hobby and light-commercial multirotor platforms that require 8-inch diameter and 4.5-inch pitch propellers. Intended as a direct replacement or an upgrade option, the blades provide the intended aerodynamic profile for stable lift and predictable thrust characteristics when paired with compatible motors and electronic speed controllers.
Advantages
The propeller set offers uniform manufacturing tolerances and consistent blade geometry to reduce vibration and improve balance across rotors. Its two-blade design simplifies matching thrust and efficiency for a wide range of motor Kv values, and the moderate pitch supports stable hovering and efficient forward flight in typical multirotor weight classes. The material and finish are suitable for routine hobby use and light commercial applications where predictable performance is required.
Suitable for
Replacement blades for hobby multicopters with 8" diameter requirements
Light commercial multirotor UAVs that accept 8 x 4.5" propellers
Flight testing and tuning when changing pitch or diameter affects performance
Key specifications
Diameter: 8 inches (approx. 20.3 cm)
Pitch: 4.5 inches (approx. 11.4 cm)
Blade count: 2 per propeller
Set contains two propellers suitable for multicopter use
Designed for standard multicopter mounting and rotation directions (check motor compatibility)
How to use
Inspect propellers for shipping damage before installation and ensure the mounting surfaces on motors and hubs are clean and free of debris. Install each propeller according to your multirotor manufacturer’s instructions, matching rotation direction and securing with appropriate nuts or adapters. After installation, perform a static balance check and a low-throttle ground test to verify correct rotation, balance, and that there is no unusual vibration. Replace propellers immediately if any cracks, chips, or significant deformation are detected.
Usage recommendations
Use these 8 x 4.5" propellers on motors and airframes rated for that size and pitch, and verify that motor current at typical throttle settings stays within safe limits. For optimal balance and flight stability, replace propellers in matched pairs and re-balance after any repair or impact. Store propellers flat and away from heat to prevent warping.
