My name is Maxime, i’m 25, i just graduated from micromechanical engineering in Neuchatel Switzerland. I will be living there soon and guess what : the city is in front of a beautiful 220 km² lake
I’m equiped with a 3D printer and a 3 axis 6040 CNC. I already built 2 eskate and now i would like to go for the efoil ! The build is going to be slow (i’m always slow because i have tons of projects at the same time) but i will focus on making something with a great design and quality. I will also try to make a good video to show all the building process.
Actually i’m finishing the CAD. Here is the final design :
Part list :
Motor : TP Power 4070-V1 7Y 630Kv
This motor is the most powerful 40mm motor i found (thanks @alexandre)
Gearbox: Reisenauer Motor Chief 6/1
Propeller: 7 1/4x7 yamaha (from aliexpress) (Maybe the FR propeller later)
Batteries: Homemade li-ion 12S9P 23.4Ah (VTC5 cells)
ESC: ??? to determine
Foil: Horue VINI Pro XLW wings
Those french made wings are made for a low speed take-off and optimized for good stability at high speeds. I got a 30% deal at blackfriday but still expensive (400€). I really wanted high performance wings (no chinese foil) and i hope this is worth the money !
Board: Homemade from an EPS block
The 40mm motor will be integrated in the tube connecting the 2 wings (@Peter’s style) which i believe is THE way to go to lower the drag and save energy. I will try to keep the tube in 1 single piece to optimize weight and rigidity. I have some good ideas to make it waterproof and i hope it will work.
I will first build the board so it can dry a few weeks (or months ) during the propulsion system build. Also for now my budget is really limited so i can’t buy all the electronics/motor/reductor at the same time…
Thanks for following,
