Many newly launched ships are fitted with controllable pitch props and advanced skewed blade designs for maximum efficiency. While we can’t (at present) supply fully functioning CP props, we can offer a realistic facsimile of them, in a number of styles. Left or right available. Regarding terminology, ‘Skewed’ prop blades do not point straight out from the hub. Their line of maximum thickness curves backwards, and both leading and trailing edges sweep back as well, in a sickle or scimitar shape. The theory behind this is to maximise efficiency in shifting water while minimising cavitation and turbulence. Blades can also be designed to swivel past each other when reversing pitch, without large gaps and serious loss of blade area.
For this range, the reference number indicates the diameter in inches: Eg, the CP20 is 2" dia.
The typical thread types for these props are M2 (for very small props), M3, M4 and M5. You can specify another thread type if you know exactly what you need.
