Long time reader of the forum here that finally has put together my own board.
As many others here the actual building of the board itself is what has always kept me from starting my own project. But earlier this year when I noticed Fliteboard were selling their 100L Fiberglass series 5 board (Yuzu color) for 1145€ I jumped on it.
Had my first test run recently and the board works really nice. although I have no other reference
It was my first try on any foil, never been surfing or anything like that so I only managed to ride it on my knees first day. But still really fun!
Board setup is: Board: Fliteboard Fiberglass Series 5 Yuzu 100l Foil: GONG | Foil X-Over V3 - Alu 85 - Aluminium / L / Black Adapter plate: Was lucky to grab one of @Kian 's last adapter plates Motor: Flipsky 65161 120kv Motor mount: Self made from acetal. Based on designs found online. Vesc: Makerbase 75200 Remote: Flipsky VX5 Battery: 14s1p LGe65b cells. Battery case: 3D printed and laminated. Aluminium lid. BMS: 30A from FluxMotion (Charge only) Propeller: Fliteboard.
Google photo album with pictures from the build: Photos
This was my very first go at efoiling so ofc there was a lot of time not spent up on foil and falling while trying to get up on my feet.
The only number I have is the 82wh/hm that my remote reports.
Your mount def looks sleeker and I can see it being more efficient.
Right now I don’t have a good way to machine my mast but maybe some time later
Very nice @olegodo! I have two Fliteboards I’ve adapted like this. I think for the effort required you end up with a really good efoil.
Thanks for sharing the album, I’m always curious to see how reclaimed pouch cells get implemented. Seems you used rivets and bus bars to sandwich the tabs? Looks good. I have a smaller 10S pack of cells pulled out of a Volvo and I was lucky I could keep the factory tab welds.

Congrats on the build! That 100l board is a great platform.
Nothing wrong with staying on your knees for a few sessions as it really lets you concentrate on board speed and flying height control and getting the “feel” of that locked in before complicating things by standing. Lot more fun flying than crashing:wink:
Have you tried the “gears” mode on the VX5? I’ve had better success with new riders learning with that than the H,M type of throttle control.
Really nice build! Very clean! I like the battery setup! Next battery I build I will use pouch cells like that so much easier than a 100+ small cells. My current LG 2170 based battery is still 100% after 3 years so it will be a while. If you could share the STL for the battery box that would be nice!
Yes I use the 1-8 gears on the remote.
The way it is set up now I can get up on gear 6 and foil on gear 4.
Yes I kept the welded copper strips on the tabs and riveted them together.
Easy and seems nice and strong.
To bride from one “stack” to the other I used a 15x3mm copper bar as a busbar and riveted that to the battery tabs.
I used the same copper bar as terminals in each end of the battery.
I also have a 200A fuse in line just in case of a serious short for some reason.
The BMS temp sensor is placed in between 4 cells and only showed 27c after my ride
I can ofc. But it is quite purpose made for my own situation and battery cells. The box is split in to 4 prints to fit my printer then glued together and after covered with one layer of glas fiber. The lid is cnc machined from 2mm or 1.5mm (?) aluminium sheet.
Lot more fun flying than crashing:wink:
