Hi

1555 Carbon Fiber Propellers CW and CCW Rotation with Dual Mountings.

Extremely lightweight and durable, you can expect an increase in overall motor efficiency owing to the ultra thin and stiff carbon construction. The dual mountings mean these will fit on most multi-rotors. You can use the standard mounting with the 4mm shaft (ream for larger shafts) or use a tightening cover with 12mm centers and M3 bolts.

Specs:
Length: 15 Inch
Pitch: 5.5 Inch
Weight: 20g (Each)
Shaft Diameter: 4mm
Cover Plate Hole Centers: 12mm
Hub Thickness: 3.0mm
Rotation: Clockwise and Counterclockwise
