Efoil V6 - (V4 upgrade)

Hi Efoil builder team,

I upgrade My V4, with full mast carbone, new cooling VESC, new VESC (maytech V2 200A)
new board full carbone. I reduced the weight by 4kg.

Old setup

New setup

Some build pictures :

I needed to replace the silicone cables, due to the corrosion X


Very nice! How do you like the carbon monoblock mast?

it is perfect for E-Foil
I don’t know if I will use it for the wing,
but for our use in E-foil, it is a good ratio, weight, quality price

Hey Jeff, could you show me how you made that connectors from mast to usc? And how did you seal the mast cables (are they removable)?


I use bullet connector and this connector for the waterproofing
Connecteur De Fil Électrique Industriel, Étanche Ip68, 2/3 Broches, Prise Extérieure, Droit, Rapide Scre - Connecteurs - AliExpress

the mast are not removable

Looking good!!

How much does the new board weigh(with everything ready for ride) ?

21kg with 12s 12p battery

Not bad! :+1: i’ll make an effort with next build - would be great to get under 20kg with a decent battery.

I tried with VESC kill switch on 3V and AD2
it’s work, but I saw the motor running a little after the safety was engaged.
I don’t trust with this system
So I stay with my kilovac to cut the power in case of a fall

Good to know but also a sad news in some respect.
How would you translate “a little” in seconds or meters ?
Do you know if PWR or Takuma react faster with their magnet kill-switch solution?

Imo the best option for a kill switch is to apply full brake when activated. But then everything remains connected, i just override the rx signal

the propeller rotate only half a turn.
It’s nothing, but I prefer to stay with my security with a kilovac
I don’t know the magnet kill switch solution of PWR or Takuma
