Master Airscrew 6x4 RC Propeller - MAS6040

The Master Airscrew 6040 propeller is a 6x4 inch fixed-pitch prop designed for use on fixed-wing RC aircraft and electric-powered models. Identified by style code MAS6040, this 6-4 prop delivers a 6-inch diameter with a 4-inch pitch, making it a common choice for small to mid-size electric RC planes where balanced thrust and efficiency matter. Master Airscrew is a well-regarded name in RC propellers, known for consistent quality and dimensional accuracy across their range.

Key Features

• 6-inch diameter with 4-inch pitch (6x4 / 6040 specification) suited to small electric fixed-wing models
• Designed for electric RC aircraft motors — the 4-inch pitch provides a moderate balance between static thrust and forward speed
• Manufactured by Master Airscrew, a brand recognised for tight tolerancing and smooth balance straight from the packet
• Lightweight construction keeps rotational mass low, which is important for throttle response on smaller power systems
