PROPELLERKING.COM - The Store For Propeller Lovers

[superlefax]

Hi folks,

Somehow it has become my hobby to constantly and excessively design and try out Efoil propellers. In the last 4 years I have probably printed more than 50 different propellers and ridden more than 10 different Efoils (commercial and DIY boards) . All in the name of science of course

I have optimized the best propellers (efficiency, speed, smoothness) from each category:

• 2-Blade
• 3-Blade
• Folding propellers

This is the electric watercraft forum...

I was looking at the props on the website. Nothing about connectivity.

Are efoil propshafts standardized?

The latest thing in boating is the toroidal propeller. Expensive in metal, but there may be some printed versions out there.

Toroidal propellers: A noise-killing game changer in air and water

These strangely-shaped twisted-toroid propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, they're also showing some huge efficiency gains.

Great are our leader will love to see this Yes Justin. He was building an electric sailboat 25 ft and somehow going to engineer a DD bike hub motor for power.

No, It Is Not A Helicopter! Just A Man Riding A Bike With A Propeller

Chances are, you haven't ever wondered what might happen if you put a massive propeller on a bike. Well, here's a video that will answer this question nobody was asking.
