Hey Peter, i really Like your concept anderen would Like to build a prussian Style sister model. What Motor did you pick and did you make the Aluminium stuff yourself?
Really nice build! Also thought about building with the duct as the rear wing, less parts=better and less drag. Our new setup os modular so think we will try that and see how it work out.
@Jsonnett Let us know if managed the cooling!
@Lukas Respect to the monofoil rider 
Instabilty is what I totally want to avoid, so the overal construction has to be very stiff and adjustable in angle of attack. l’ll post some pics when I finished building it.

Hi,
I am from bavaria too (currently living/studying in munich). I really like your concept! How did you build/made the wings? Are they 3D-Printed? Are you willing to share the files? I am studying mechanical engineering, so maybe we could share our experices/ideas 
Where are you from and where are you riding it? 
Can you log how many amps you draw peak? I would like to rebuild it with the ESC (a VESC) in the tube and with an inrunner direct drive ~200KV and a bought ducted prop from aliexpress (80mm, @peak 3000W ~27kg thrust) the 8010 one.
Did you see the multistar batteries? I guess the 4s 16Ah are the cheapest (per Ah).
Best,
Chris
@windchaser Sure we can meet --> see Email
@Giga We can talk about the concepts, of course, and munich is not to far, so if you’d like to come here on weekends, just tell me.

Servus Peter!
Bin extrem begeistert von deinen Konstruktionen.
Ich stehe ganz am Anfang und möchte über den Winter ein E-Foil bauen.
Habe viel Erfahrung im Modellbau und bin viel am Wasser unterwegs (Katamaran Segeln) und suche neue Herausforderung.
Komme aus Salzburg und würde mir sehr gerne deine Teile in Natura anschauen.
Von welcher Ecke in Bayern kommst du und wäre ein Treffen in naher Zukunft möglich?
GLG aus Salzburg!
Hi Peter, like your build, i am from norway, my engles is bad, sorry. I was thinking about your prop. My idea is to put a ring on the prop. Not a duct.This has several benefits. I can absolutly nothing about props, but i read that alu prop has bigger “slip” because it is soft, 2 cavitasjon,3 some safty less than fix duct more than nothing, less parts. Maybe more. Anyway just some ideas, Please tell me what i am missig, i am learning. Love your work. se the picture.
Regards Aslak
Peter, I see from the pic and video that your front wing looks to be between your feet. On both my kite foil and the e-foil I am helping test my rear foot is in front of the main wing.

Hey Peter, could you specify your parts list? I would Love to recreate your project

Great layout Peter, we have been working on a similar setup but with smaller ducted prop for safety reasons, but I think you nailed it that the fuselage should be the housing for motor.
Hey @Fancyfoam, I know that many are creating stability with negative angle of the rear foil, but this creates drag that I don’t want to have at higher speeds. So my center of gravity is slightly in front of the main foil and thats enough for me. I go even little further, my rear wing creates lift in higher speeds, so the angle of attack is decreasing with increase of speed, and the system plains itself. To reach >20 knots, this is quite uselfull, to not waist too much energy. Stability an efficiency is always a little conflict
@Felixeik I’ll try to prepare a list next time.
Thanks @VeFoil, your long torpedo like housing could easily be used to replase the fuselage
@Peter I plan to use a kite board about the same size and volume as your’s, but I was wondering if it as enough volume to float with you, the foil, the battery pack, etc on the starting phase when you have no speed. I ask as almost all the others are using much thicker boards with an important volume. Thanks!
Hey,
the board has only 20liters, so it’s floating by its own, but not at all with somebody on it.
You would need to lay down until you have a certain speed (~8knots) and then surfing is like a wake board ing. You can then lean a little back and start flying. In my opinion it’s lots of fun, but you will get wet and you will need some trials until you manage it

Thanks it helped me a lot understanding how it will work with such a low volume board! 
Love your build! What do you think about a catamaran style board?
@MaxMaker , just a thought, why not just a V shape, more volume in center, better for mast assembly and integrated box 
I could do. But will that not cause more drag?
You are going to fly, not be on the water. The board shape has little impact (apart from air resistance)
Hi @MaxMaker, Yes more drag with V shape vs flat, i was just thinking V shape vs catamaran shape that you was asking of.
Think area, more area more drag(rule of thumb).
I think flat shape is best, because less drag (small motor), more stable at no speed, easy to mount mast…
Good question tho
