## Summary description

2-blade propeller set by GRAUPNER for multicopters, size 8 x 4.5" (20.3 x 11.4 cm), model 2949.8X4,5. Designed as replacement or upgrade blades for multirotor UAVs, the set supplies matched pitch and diameter for stable thrust and efficient lift. Suitable for hobby and light commercial drones where this diameter and pitch are required.

## Long description

Propeller set for multicopter GRAUPNER 2-blade 8 x 4.5" (20.3 x 11.4 cm) model offers a matched pair of two-blade rotors engineered for multirotor UAVs. These blades provide the specified 8 x 4.5" diameter and pitch to deliver stable thrust, predictable aerodynamic behavior and efficient lift for hobby and light commercial drones requiring this size. The set is intended as a direct replacement or upgrade for compatible multicopter motor/propeller combinations and is produced by the GRAUPNER brand with attention to balanced performance.
Advantages
The propeller set features a uniform pitch and diameter across blades to ensure consistent thrust and reduced vibration during flight. Two-blade construction gives a balance of efficiency and responsive control, helping to maintain predictable power consumption and flight times. Molded geometry provides repeatable aerodynamic properties and simplified installation on compatible hubs. The blades are suitable for applications where straightforward, reliable aerodynamic performance is needed.
Suitable for
Hobby multirotor drones with 8" class propeller mounts
Light commercial UAVs requiring 8 x 4.5" propellers
Replacement of worn or damaged two-blade props
Testing and tuning multirotor setups for thrust and efficiency
Key specifications
Propeller type: two-blade
Diameter: 8" (20.3 cm)
Pitch: 4.5" (11.4 cm)
Construction: molded plastic blades with aerodynamic airfoil profile
Intended use: multirotor/multicopter applications
How to use
Install the propellers on motors with compatible shaft and mounting hardware following the vehicle manufacturer’s instructions. Ensure correct rotation orientation: pair clockwise and counterclockwise blades as required by the multicopter configuration. Tighten mounting hardware to the recommended torque and verify that the blades have no cracks, chips or deformities before each flight. Balance the propellers on a static balancer if vibration is observed, and perform a short low-altitude test hover to confirm stable thrust and motor temperatures within expected ranges.
Usage recommendations
Replace propellers in matched sets and inspect regularly for wear. Use the specified 8 x 4.5" size to maintain designed lift and control characteristics; changing diameter or pitch may require motor and controller re-tuning.
