Hi Hugh,

this prop is from Russia modelboater .They use this design when the water is rough and wavey .The prop hold the strut down on the water prevent the boat boundzing around.I think i got it as they didn´t use them very much, other propellers are faster .

Christian, what are you using to add cup to your props? Also if you can find me some or direct me to a source of props with this sea gull cut id appreciate it greatly. Just wanna play around and experiment a little.

Christian, you know of anyone that offers the tether props counter rotating? Though that sounds goofy as all.

Hi Hugh,

as the tethered guys all run counterclockwise they all have only the right hand propellers. Du you know someone who can design a propeller in CAD .If so we can switch the cad drawing data in stl dataformat witch is need for stereolitography . With such data my friend can print right and left hand propellers like one egg twins .
