Master Airscrew 9x4 Wood RC Propeller - MAS9040W

The Master Airscrew 9x4 wood propeller (MAS9040W) is a fixed-pitch wooden RC aircraft propeller designed for use on glow-powered and electric fixed-wing models where a 9-inch diameter, 4-inch pitch prop is the correct specification. Master Airscrew is a well-established name in RC propellers, and their wooden props are a popular choice among pilots who prefer the natural vibration-dampening properties of wood over plastic. The 9x4 size suits smaller glow engines and lighter electric setups, making it a straightforward replacement when an existing prop is damaged or when setting up a new airframe that calls for this pitch and diameter combination.

Key Features

• Wood construction provides natural vibration dampening, which can reduce stress on motor mounts and firewall fittings
• Pre-finished surface with a balanced profile for consistent, smooth rotation straight from the pack
• Style code MAS9040W makes it easy to reorder the exact prop when a replacement is needed
