4045 (4x4.5) 3-Blade Propeller, Purple (CW + CCW)

Four-inch three-blade propellers in the 4045 size — 4 in diameter with a 4.5 in pitch — sold as a clockwise and counter-clockwise pair for 4-inch quadcopters and multirotors.

Key features

• Three blades: extra grip and thrust per revolution over a two-blade prop of the same diameter.
• 4.5 in pitch: steep for a 4-inch prop, favouring top-end speed; expect higher current draw than from a lower-pitch 4-inch prop.
• CW + CCW pair: one prop of each rotation direction; a quadcopter needs two pairs for a full set.
• Purple finish: easy to spot in grass and to tell apart from other prop sets.

Match each prop's direction to the motor rotation set in your flight controller, and keep a spare pair with your batteries.
