EMAX 1045 (10x4.5) ABS Propeller Pair (1CW+1CCW)

EMAX 1045 propellers in black ABS, sold as a matched pair of one clockwise (CW) and one counter-clockwise (CCW) prop. The 10 x 4.5 inch size is the usual choice for F450 and F550-class multirotors and other slow-flying builds on low-KV motors.

Key features

• Two-blade 10 x 4.5 inch profile for efficient hovering on low-RPM motors
• One CW and one CCW prop per pack: a quadcopter needs two packs, a hexacopter three
• Wide, thin ABS blades that flex rather than shatter in a crash
• 15° tip design to reduce tip vortex
• Plastic shaft reducer rings supplied to fit common motor shafts

Specifications

• Diameter: 10 in (254 mm)
• Pitch: 4.5 in
• Blades: 2
• Material: ABS
• Colour: Black
• Pack: 1 CW + 1 CCW

A typical pairing is a 2212 motor of around 900-1000KV on a 3S pack, as used in most F450 kits. Fit each prop to the motor that spins in its direction, check the balance before flying, and keep spares, since ABS props bend and chip with use.
