I'm Ready to start.
First up will be the pylon ; had some good ideas run past me
for this part of the build.
I'm going to order the highest density foam this link below has in stock, and
have them hot-wire out the airfoil that's 100cm long.https://www.flyingfoam.com/content/what ... ld-i-use-0
Thanks --ronnie-- on page 2 of this topic !!
I'll build (2) wood stiffeners out of (2 X 6) and a bit of glass on both sides
to keep them straight. Next i'll contact-cement the cradles from the foam
wing to both stiffeners , and glass the concave parts with (3) layers
of 3oz , to stabilize the foam and tie them to my 2x6. This makes a Super-cheap
and Fast female mold ; just need alignment pins . The only place that will need work on the
part that comes out of the mold, will be the Leading Edge.
I'm planning on getting 20 or so low resolution parts out of this mold, so
if i screw-up the first pylon, i won't loose too much work, and a second one is
only a day's work away.
That N66-012 in the link above looks like it could be made Strong and
Stiff with little weight , because of the Thickness distribution ; i'll need to ask
around if it would work in water, or the NACA-0012 would work just fine.
I'll talk about the lay-up After i got the mold ; but the Pylon will be the
first thing i make.
The first one will have a balsa core, the second one
will have Nomex-honeycomb ; both will use Stitched 12K carbon and
pre-made carbon rod for strength.
There IS cheaper stitched than this :http://cjcompositestechnology.com/produ ... rbon-fiber
