Hi everyone, as i never took time to work on this project i sell my propulse propeller.
This is a high quality plastic propeller with adjustable pitch function (can twist the blades)
Model N°6902 (25-60hp boat range).
Brand New (sold 112€ by the shop) I never used it. Sold in the box with documents.
THE IDEA :
The blades can be removed so i planned to 3D print a new hub smaller and then cut the blades a bit.
This could allow to test different pitch with the same propeller.
Are you the lucky buyer ?
To anybody out there: how could we modify the pitch as a function of the speed detected by the ESC ? Low pitch at the begining, 5-6 in pitch full speed for a 140mm diameter prop.
No, I’m not. Just after I signalled my interest, I did notice, that I would need a left hand propeller.
Regarding your question the offered one was an APP (adjustable pitch propeller), not an CPP (controllable pitch propeller). You need a CPP to change the pitch under flying. With an APP you will go to shore and take a tool and partly demount and reassemble it to change pitch. The CPP in naval use are comparatively large, heavy, expensive and need (more) maintenance.
