Nice.This really should be a components type of thing. If they can get 12K for it good for them...but plop the batteries into a board...wire the mast and buy an engine...have an outlet for the remote on top of the board.

I'd be interested in getting an engine for sure. Here is a guy who published it all on youtube. In 13 parts.

Yes I completely agree. im just finishing up on my quick connect brackets for My eFoil http://www.diy-electric-hydrofoil.com/d ... eo-series/ so it attaches to almost all brands of foils, not the mast, but the fuselage with two hex/allen bolts so you can zip around, then unbolt, unplug, and go back out kiting or whatever you want..

Where do you put the wires and battery?

for testing, Im'm using a water-box with batteries, and wires up the mast, with the box on top of the board, but we are designing a waterproof torpedo battery pack that bolts onto mast/fuselage as well.

The guy in the video is bored out of his skull. Just standing there reaching unexplored horizons in watching paint dry and lawn mowing.

Not everybody has the same threshold for having a Fun time of it ; some people just
need a computer to live life vicariously through someone else, and others
like me need to be maxed out on a HG for three hours at a time to call it a
fun day. I ain't gonna bash on a guy that needs or wants less adrenaline than me to live.

Cool about the different platforms you are trying for batteries.
I wonder which will work/feel better.
If all is going underwater it could maybe integrate into a fuselage with a lifting shape, so you avoid adding wetted surface without adding lift. Just an idea, maybe a lot of extra r&d though.
If top speed is in line with others (bit over 20 kt's) you could get there with a pretty thick wing/fuse and have better low speed take off and battery life since most power is used to take off.

I , "Need" a good Rush , (a Lot) ; or i get sick of TV , like Fast !! :lol:

NOT braver than you sir ; just a $hit-load more Stupid ! :lol:

The Mountain i ran off of on my flying trip, was 3,500ft , (1066-m) high
from top to bottom. With 12-mph wind ; the glider will lift me off in 2 steps ; but i hold in
to lower the AOA, so that makes me run much faster , but it's safer to
launch with more speed.

So here's a comparison between my 13m Edge , and the glider pictured above :

The 13-m Edge pulls me up out of the water at 13 knots , and tops out at about 30 knots.
The Glider is close to 16-meters,with an AR of 10, and stalls at near 16 knots , and tops out
at over 70-knots, in smooth air. So - Ya see , the airfoil on my glider , makes
for a MUCH wider speed-range , (over double the Edge) ; even though it has 3-m more aria.
Maybe LFAK would like to argue about airfoils, and what their effect is on flying machines ? :lol:
