Master Airscrew 3 Blade 7-4 RC Propeller - MAST0740

The Master Airscrew T0740 is a 3-blade 7x4 propeller designed for use on RC aircraft requiring a 7-inch, 4-pitch prop configuration. Master Airscrew is a well-regarded name in radio control aviation, and this three-blade design offers a compact diameter option where a larger prop won't fit or where the aircraft's power system is matched to 7x4 geometry. The three-blade layout moves air differently from a two-blade prop of the same diameter, making it a useful choice when you need a shorter prop without dropping to a smaller standard two-blade unit.

Key Features

• 7-inch diameter with a 4-inch pitch, suitable for motors and ESCs matched to 7x4 loading
• Three-blade configuration provides an alternative to two-blade props of the same diameter
