Master Airscrew MR Series 7x3.7 Prop (CCW)
by Master Airscrew

The Master Airscrew MR Series 7x3.7 CCW Propeller is the essential clockwise (CCW) counterpart to the CW version, providing the balanced torque required for stable flight on VTOL drones and multi-rotor platforms. Optimized for high-efficiency operation, this 2-blade propeller is a top choice for sUAS contractors, government drone initiatives, and STEM educational programs that demand precision and extended mission endurance.

Crafted from Glass Fiber Reinforced Composite (GFRC), this propeller offers the structural rigidity needed to maintain performance during rapid RPM changes common in tactical reconnaissance. Like all props in the MR series, it is factory-balanced to minimize motor vibration, ensuring steady sensor data and professional-grade video capture. With its 7-inch diameter and 3.7-inch pitch, this CCW propeller provides a smooth and predictable throttle response for commercial and specialized aerial operations.
