Ripmax Folding Propeller 12 x 8 4.0mm Z-Hub CarbFXThis simple and beautifully made carbon effect (CarbFX) folding propeller features a modern 'Z' hub design.

This hub also features a purpose designed tapered collet adaptor. The spinner and blades are supplied in a realistic carbon effect finish without the hefty price tag of real carbon. Spinner
