Master Airscrew 3 Blade 6x4 RC Propeller - MAST0640

The Master Airscrew T0640 is a three-blade 6x4 propeller designed for electric RC aircraft requiring a compact, balanced prop in the 6-inch diameter class. With a 6-inch diameter and 4-inch pitch, this prop suits a range of small to mid-size electric fixed-wing models where a three-blade configuration is preferred over a standard two-blade for tighter, more controlled thrust delivery. The style code MAST0640 makes it straightforward to reorder or verify fitment against your motor and airframe specs.

Key Features

• Three-blade 6x4 configuration — 6-inch diameter with 4-inch pitch suits electric motors commonly used in small to mid-size fixed-wing RC aircraft
• Three-blade design produces more thrust in a smaller diameter compared to a two-blade prop of the same size, useful where ground clearance or airframe geometry is limited
• Intended for electric-powered RC aircraft — not suited to glow or petrol engines
• Compact dimensions make this a practical choice for park flyers and smaller sport aircraft running brushless motor setups
