Hi,
I think I have now all the information together to actually get started:
Member 60: I found a place close to Vienna that sells pine, sitca, Douglas and
lots mor, ecxept plywood.
the length range from 4 to 6 meters, It`ll all fit into my car, just
sticking out a little.
I`ll use spruce except for the spars. And some local pine. The local pine is
cheap, but not suitable for spars, because of the many imperfections. Only
spruce has a secific weight of under 550Kg/m³, and for the spars I`ll use
Douglas fir. I calclated a weight punishment there of only 2kg when
comparing it to spruce.
I`l perform some bendibg strength tests at a local university with a friend
that works there for good documentation. I did a short comparison of prices
from Aircraft spruce, to Muehlbauer, who has this huge wool supply, with
aircraft spruce about 4-5 times more expensive. 
The paperwork: 
Took me weeks to speak with different officials at he local aviaion
administraion, to find out the following:
In Austria, the ULF1 is defined as an ultralight vehicle, under 120kg empty
weight, that would need an airworthness cert. which in turn would cost 2300
without building supervision. one could cunt up to about 5000 to get it
flying, just for the paperwork. Considdering the value of an ULF 1 no one
would do such a thing.
 
But it wouldn`t be Austria if there wasn`t a provision. Because it is a foot
launchable ultralight vehicle, it can be handled as what is unofficially
called a slope glider, the same holds true for a para glider, and those
ultralight vehicles don`t fall under the urisdiction of the aviation admin,
but are governed by the Austrian Aeroclub. So actually one has the choice to
either get an airworhiness certificate and build an airoplane, or build a
slope glider, which in turn may not be flowen outside Austrias airspace.
Considering that a homebuilt needs a permit to fly in other countries
anyway, this isn`t really any restriction.
The Aeroclub registeres the vehicle, and determines its airworthines
according to the manufacturers instructions, whatever they might be, as long
as the manufacturer certifies that the vehicle is manufactured and
maintained to the lates state of technology. What ever this may be. 
 
Here we are much better off than one might be in Germany, bulding an ULF 1
was popular there, until they took it out of the DAEC jurisdiction one year
ago, back then it used to be just like here n Austria. Now coss for an CoA
are worst than here. 
 
I have a question, there is an ellevator for sale, believe in Germany, its
alread covered with ceconite, for the price i might be worth buyin it, does
any body have to say something about it? 
 
WIth the latest terror going on and more to be expected, i won`t buy any
Member 60 next week, to tell the truth I`m shook up, watching our gvt. and
Germanies. I`m running a business, and nobody knows what it`s going to be
like in 6 month.  
Truely,
