This simple and beautifully made carbon effect (CarbFX) folding propeller features a traditional 'H' hub design. The 'H' hub keeps the blades parallel to each other either side of the spinner keeping the complexity and cost down over the offset 'Z' hub (also available). The spinner and blades are supplied in a realistic carbon effect finish without the hefty price tag of real carbon.Spinner Diameter: 30mmShaft: 4.0mmNote: The colour of the metal blade holder may vary from the image above.
