NZ carbon fiber kevlar build

This is my second build after the shitshow my 36 kg, leaky, wobbly and sharp first build ↓↓↓

Its 160 x 70 x 18
Flipsky 65161
Makerx g300
Gong x-over xl v2 75cm
Amorge power 40t 14s 24ah battery
VX5 remote
Flite prop


Shaped with a wood saw and a hot wire cutter


Sanded rails down


Glassed hatch in first used super 77 contact adhesive to make the corners sharp


Poored moldstar 30 for the seal




Used carbon fiber reinforced plywood as a sort of half stringer to reinforce the foil box area and distribute the load, board has 380gsm carbon on top and 200 gsm carbon fiber kevlar on the bottom.
Board weight ended up being 30 kgs which im not happy with but at least it is lighter than my last build
10.5 kg for board and hatch (2.2 kg)
10.5 for battery, esc and heatsink connectors etc
6 kg for mast and motor
3kg for wing

Dual hatch design for redundancy as i didn’t trust the mast seal and plan on removing the mast every time i use it.

It Has an on off switch and a charge port inside the round hatch so i don’t have to constantly open the main hatch which is 100% waterproof.

The mast is mounted with M8 screws threaded into 8 mm of aluminum plate. It’s waterproofed with M8 rubber washers and a custom Moldstar seal. The washers are being over compressed and are currently leaking, so that’s still a work in progress.

After my fourth ride im up to 15.5 km on my battery which i think is great considering my 110kg and high board weight.

There’s room for a second battery which im waiting on although probably wont use it much and am thinking about rebuilding my shitty old build into a fliteboard fakeboard and useing the old parts.

Technically it’s not quite finished yet. I still need to do a final sand and add thermal paste between the VESC and the heatsink.

Nice silicone hack there!

My dad once used carbon fiber/kevlar (some kind of hybrid cloth), building a board (jetboard) and will never ever do this again.

Problem was when sanding the kevlar it ended up looking like a sanded fluffy tennis ball.

Your build looks nice by the way.

Kevlar is beneficial in lower layers. But should never be on the outside because of the sanding issues. Look into how may boats and racing kayaks are made with it. Excellent impact resistance if in the right place.

Definitely had the same thing luckily only in the back two corners i think you need to add a lot of resin while laminating so its thick enough to not sand through so vacuum bagging might not be ideal
Fortunately i forgot to buy a fitting i needed so i only ended up vacuum bagging the hatch and motor mounts

I thought from one of your previous posts you were using V3 mast???

You can use the V2 wings on the V3 mast with the fuselage from gong. It’s a v3 to v2 wing set fuselage. Like an adapter! Very clean.

Nah im too cheap for that

This is what I’m referring to

Yeah, i went with a v2 because it was cheaper
