I found this web and Im thinking about to build my own efoil. I was windsurfing some time ago and Im also rc modeller and have 3D printer. I spent two days reading about hydrofoils and e-foils and I have few questions:
I already sold all my windsurfing boards so I need to buy some used. Im almost 100Kg, what size do you recommend? 130L at least? Im afraid it will be very long and huge + heavy. Also what should be surface of wing? Im planning airfoil Aquila 9.3% around 700-800cm2 because of my weight.
Id like to test dual outrunners propulsion system in one tube directly placed and cooled in water. My friend tested this on RC boats and it works for 2 years with no issues (not salt water only lakes). Therefore Im trying to stay under 24V (6S Lipol) for each motor to stay on “safe side” I think with these two outrunners it should work: https://hobbyking.com/cz_cz/kd-53-30-high-voltage-brushless-outrunner-190kv.html If Ill go around 80-90A each, I can get maximum 3,5 - 4kW. I hope this will be enough (I found 2kW should work)
Do you think 25V DC in not salt water is safe for human? I dont want to die during this experiment
- is there any free 3Dsw for boat propellers drawing and calculations? I have one but only for airplanes.
Thank you all for your opinions and help
