I ride inflatable wing foil board and I could say my e-foil feals much stiffer than the inflatable one. I’m also considering using this board for winging also.
What is the weight of V1 and V2, board only ?
I haven’t weigh anything yet. Will do it soon.
But where’s the maiden unpacking and packing back up?

Will add that later.
I’ll be making foam insert to prevent things to shift around.
This V2 has four skins of fiber glass instead of two, price of replacing foam by vacuum, price of the board stiffness 
So v1 had 3 skins CF 163g/m² on outside and 1 on the inside and it was just hand laied and constructed from 20mm xps plates. The weight is 8.3kg
V2 is 2+1 CF+diolen 200g/m² on the outside and 2-3 on the inside all vacuumed on 13±2 mm xps CNCed. The weight is 6.6kg
The drivetrain (motor, mast, foil, prop, all electronics and box) is 10.5kg.
And finally i got to weigh my 13s10p battery and it is 11.5kg.
So V2 is 28.6kg + cables and remote

Hey - how are you finding your Raiden7? i just got one and having some cooling issues. I am passively cooling it, attached to a large aluminum enclosure with thermal paste. The VESC gets to 70C pulling 70 amps in about 2 minutes. As soon as i reduce the throttle the temp quickly drops back down to 40-50. The enclosure is only just warm, so i think it’s the thermal pads that is the bottleneck with the cooling.
I might try using a piece copper sheet and thermal paste instead of the thermal pad tomorrow and see if makes any difference.
When I ride it comes to max 60°C and it cools down fast after slowing down to cca 40-50. The temperature drops down to 35 in 5s after a fall.
But I use watter cooling without pump.

Strongarm a good thermal paste should be better than pads. Let us know if it actually worked better with paste.
The thermal pad is 1mm thick - will thermal paste be ok/improvement at spanning this gap?
I have some 1mm thick sheet at copper at home, I was thinking about putting a piece of this below each FET, once I figure out if the vias are electrically conductive or not.
Vias are coductive.
I also have termal pad but will upgrade to paste when I get home.
hello thomaz
I just received ESC Raiden7 today.
I really like your idea of mounting the ESC on the mast.
Are you willing to share the mast box CAD files?
I’ve made it in fusion 360. What format do you need?

OK, he also works at Fusion 360.
This is CAD that I can use for free.
f3d (fusion) format will be good
