Re: revolutionary twintip board

Looks like a carbon twin tip to me.. two sides, two pads, 4 fins.. Any details? Am I missing a point? Hi, it is a board made with resin infusion. The first one's have been made around 2004, so nothing new here. On this particular board the bottom is made out of 0/90°, I hope for the owner there is ...

Re: Levitaz foil broken mast needs help.

I thought Levitaz foil is full carbon very solid and indestructible but not this time . Very disappointed. The wing is perfectly okay but the head neck just broken by itself. Still less than 24 months under warranty, but they ve done nothing about this. Hi, nothing in the world is indestructible. W...

Re: Polishing PVA release agent?

I'm not great at spraying PVA release agents. There are always some imperfections. But its very water soluble. Has anyone tried just dampening it and trying to smooth it a bit? Maybe mist it a bit with a spray bottle, then use a lint free cloth? Hi, PVA can not be polished. But you can spray it glo...

Re: Unboxing: Moses Aluminium Foil Kit

That's a bit surprising - why do you think it would be stiffer? :?: I do not think it is stiffer. I know it is stiffer. I have tested the flex. -- Gunnar I'm not questioning whether it is stiffer ...

Re: Twist Wings liquid force impulse

Hi,

there was a song from Elvis Presly from the year 62 with the title " Return to sender "

High Modulus Carbon

Greetings Like I said for month's or years. Listen to this guy. Additional to his findings, I have the suspicion that some of the companies don't use epoxy but some resigns that cure extremly fast, to speed up the production line and some of them might use chinese carbon, which means glas and colour...
