I tested today my last Efoil V5, and it was a sucess.
The test today with a water at 4°C
The idea was to take the parts of my V3 to make an Efoil as light as possible.
I took the flipsky motor, the Vesc and the lion battery.
My old Efoil 24kg
and the new one full carbon 19kg with battery and wing

Description of the steps :
I used a 70 cm carbon gong mast
I used the Manu clamp, which I had to modify to adapt to the carbon mast.
For the board I used a EPS with Surface coating based on epoxy resin, microballoon and colloidal silica. and all the stratification was done under vacuum.
Size 119*57 and thickness 9.5
For the link mast and board I used 4 carbon inserts
I reused the vesc flipsky cooled by water, to transform it with passive cooling without pump
And encapsulated with silicone
For the top cover I used 9 carbon layer
For the battery I used my old samsung 30Q 12S 10P ( 1H15 autonomy)
but I changed the BMS because the thickness of the old one was too big to fit in 9.5 cm
I used the same charging system as my V4
And finally I still have the same security system with a 48V kilovac and
magnetic switch
