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...

Has anybody experience with this ESC: https://hobbyking.com/de_de/yep-120a-hv-4-14s-marine-brushless-speed-controller-opto.html Or any other alternative for the Seaking 130A?

@Hiorth: but the small board fits perfectly in my car ;)

Finally I did my first "surfing" on my brand new machine. I really had to struggle with water leakages in the propulsion system. My 3d printed parts weren't watertight at all. I had to spray them with clear coat and silicon. Everything is fully unscrewable which is a big advantage to find the...

@Vincentbraillard: Your printing looks quite nice. Which propeller are you using? @all: I think I found a good solution for cooling the ESC: https://www.banggood.com/AEORC-Large-size-RC-Water-cooling-Radiator-System-WCHS-300-p-1094759.html?rmmds=search The radiator (without the fan) goes...

@Hiorth: That sounds great. I will wait for your new prop guard design :D . Here is some other interesting cooling method: https://hobbyking.com/en_us/hobbyking-liquid-cooling-system-for-rc-cars-with-self-circulating-pump-and-radiator.html?___store=en_us @gege2000: How much you paid for the...

I'm still not sure which hydrofoil I should buy @Alibaba. Should I go for the SUP Foil (1) or the Kite Foil (4) ? @Hiorth: Are you planning to make the desgin of the propguard more safe ? I think I'll buy the 550 KV motor.

Hi guys, in my first post in this forum I want to share with you my design of the propulsion unit. I took the design of pacificmeister and hiorth as a template (big thanks for that!!!) and enhanced some points. My unit is completely unscrew able, nothing must be glued. Also there is a removable...
