Onda633 fuselage too heavy, any way to make a carbon one?

Postby omg » Wed Dec 12, 2018 11:23 am

For travelling I find the standard fuselage very heavy, so is there any way to make a carbon one or modify some other manufacturer's lighter fuselage to attach the wings and mast to it, please?

I am sure I am not the only one with this problem?

Thanks :thumb:

Hi omg,

yes there is a very simple way, while with the huge effort to build a carbon one or match another carbon fuselage you may save in the very best case 300 gramms.
But just when you build it with bigger diameter and therefore with more drag, as on the picture before. But there is a way to reduce drag and weight both significantly:

I saved on the Gong foil:
Original fueslage + Stabi
1,05 kg + 0,41 kg = 1,46 kg

0 - convertible fuselage without stabi: 0,33 kg !

So I saved a relevant 1,13 kg !

… which means to reach this, you would have to build your fuselage not out of Carbon, but out of strange matter with negativ gravity :wink: :D

I am sure the Onda will be easy and great for mono, so just try it.

If you want to go light, go mono :wink:

This is simple really.

Buy a hard wood 32mm rod, shape it as you need, and wrap in 3-5 layers of carbon. I can do that in less than few hours, but I do have a lathe to make a bit hydro dynamic profile.

Horst, you are like a Don Quixote, my complete DIY foil is 1.8 kg. No board.

Downunder’s gear can be 30% lighter than normal gear because he weighs 30% less. Occasionally he remembers to include this caveat in his postings. No disresepect, he builds nice looking stuff!

Yep,

Horst is also <60kg :)

The windsurfer carbon mast has really thin walls, can stand on it no probs, where is like 35mm in diameter.

So having wrapped wood in carbon with 28-30mm diameter should be strong enough for heavy riders. It all depends how is wrapped, as you know...plus, the grain position.

You probably mean a fuselage ;)

The lathe work is just by the eye, the mast slot just by the chisel.

But if you think about the mast, yes, some was published on ytube

Yup, if posting about sizes and ranges, and also weight of gear indeed, always include your own weight if not average weight which is defined as 75-80 kg (165 to 180 lbs) :thumb:

Thats a bit over the top Frank...

We are not discussing weight or equipment here. Or soon we will all need to write a disclaimer in small print to make everyone happy.

I will not spend my time to do that Im afraid.

The rider weight in DIY is irrelevant, its about the process, commitment and learning new skills. Plus repetition, mother of all skills. This is why there are no TT DIY builders any more. For sure the first fuselage will break, nothing to do with rider weight ;)

As bwd says, no disrespect...
