Master Airscrew Scimitar Prop 11-4 RC Aircraft Propeller - MASS1140

The Master Airscrew S1140 Scimitar Prop is an 11x4 RC aircraft propeller designed for fixed-wing electric and glow-powered RC planes. The Scimitar design features a swept, curved blade profile that reduces noise and vibration compared to straight-blade props while maintaining efficient thrust output. Style code MASS1140 identifies this as the 11-inch diameter, 4-inch pitch variant — a popular size for mid-range electric park flyers and trainer-class RC aircraft.

Key Features

• 11-inch diameter with 4-inch pitch — suited to electric motors and glow engines in the matching power range
• Scimitar blade geometry reduces tip noise and smooths airflow for quieter, more efficient flight
• Moulded from durable composite material to resist flex and withstand normal flight loads
• Consistent balance straight from the pack, reducing the need for extensive hand-balancing before fitting
• Fixed-wing application — compatible with standard prop adapters and collets for most RC plane motor shafts
