With my 30A battery I ride one full hour , 15.8 km .
The battery get little bit warm after one hour of continues ride on 3/4 gas (most of the heat is generated from the bsm, I got bsm on discharge).
The peach on the prop is five.
It’s the exact prop like Silvio has (thin build 45 mm)
But I feel like my engine still got plenty of power and I’m planning on 6 peach prop with the same diameter or even higher peach with lower diameter.
Only 273 kcal. Very low consumption

In load the battery works at 49 \ 52V
Which is fast enough with 390 kV and 1: 5
12s 18650 stays at 49v?
14s 58.8v at fell charg .
the bsm turns off the battery at 43.9v .
My charger is 10A
(There are more powerful, not recommended)
I do not understand much about electronics.
I was advised by people who build batteries,
This is the best way for the purpose of results
durability (Hope for at least two years of use)
stable battery = safety
Ok thank you , 51.8v (3,7x14) , that is what i was planning for my built , 18650 has lower load number then lipo …
more info about battery please …price …shop…etc
thanks
Router bit bent and spinned itself off? What kind of a bit is that? Look like fork <:P
Flat Boring Bit\Spade Bit , it was short so I welded him another one,
but that was’t the problem . i inserted the drill only 5 mm into the router
because it was short and after welding instead of putting it all the way
i just lowered the height limit of the router ,i was in a hurry and that was stupid . in the end I ripped off styrofoam studs with my fingers

bms 150a from AliExpress ,I will ask for a link from the person who bought the bms for me
Pure nickel, lead conductors soldered to a custom busbar made of copper
And I’m going to wrap the battery in fiberglass cloth + epoxy and waterproof connectors
He held up 10 hours of work even though he was not supposed to work in more than a few seconds.

Everything works well
I got self-confidence and went out to cross a small lake (unaccompanied)
everything was excellent and the level of self-confidence rose to the sky.
two days later I flew along the beach
And I got stuck in the rocks
I was sure that everything had broken, luckily it was only one part
mast clamp ( abs print)
when I hit the rocks the tail hit the propeller
The silicon coating from the wires is torn but the engine still works
I turned it on when I got out of the water and it was a little electrifying
So I did not deal with it and I ordered a sea rescue because I got stuck in a problematic place ,(Had to lift the board 6 m above the breakwater and then walk with him 2 miles with 32 kg)
Wow, this could have been bad. Did the rescue guys say something about your efoil? 
Yes
it is a private rescue company and they said - thank you for 250 Euros

Ouch! 
Cheaper being dead nowdays 
Hi,
Could you provide some information about the foil Dimensions? Or some more detailed reference? In the description states Chinese A1 but i am failing to check the dimension of such foil.
Best Regards,
João Rebelo
Does your total rig weigh 32kg? Mine is 30kg and I was feeling like that was way too much. With me on board it’s 122kg.
It is a link to the foil I bought
Now they have a new one that weighs only 3.2 kg with a new design
