OK, here it is...the new version of what became a P.D.U. (Polyvalent
Deposit Unit...hum...just the first name I found)
Thanks to the remarks, I made a few changes on the flying thingy and
added some samples of what it can be used for...
I'll try to improve everything and to find other things to use...after
that, I'll need an environment to demonstrate some of the P.D.U. abilities.
comments/ideas
thanks.
David.

Are those cut-outs in the legs the counter-rotating fans? I though about
it since your last post and thought you might put in no-tar baffles.

Yes they are, I was looking for a not too bad place to put them...it is
the only place I found...
Sorry, but I don't understand the second sentence...what are no-tar
baffles ? (in french if possible...)

No-Tar, "No Tail Rotor" helicopters use a variety of methods to battle
counter-rotation while maintaining directional control.

Didn't they try some helicopter designs without tail rotors at
all, but posessed two main rotors going opposite directions?

I like.
Reminds me of a three legged animation (Rune?) I saw on p.b.a
the short time I visited (a bad idea with my slow modem).

There are some helicopters built using that concept, like the russian
Ka-50 Hokum combat helicopter. It has many advantages over the
traditional approach.

These are funky! :) I dig 'em.
But what I really want to know is how you did the [drill]? I don't have much
time to play with Pov-ray these days, but I had recently been trying to make a
realistic wood screw, and couldn't figure out how to do the 'screw' part.
Thanks!

here, the drill is:
// the values of the various radius may be wrong, it's a freestyle writing
difference {
cylinder {<0.0, 0.0, 0.0>, <10.0, 0.0, 0.0>, 0.75}
blob {
threshold 0.6
#local nbS = 500; // nb of sphere for precision
#local nbT = 10; // nb of turns
#local ii = 0;
#while (ii < nbS)
sphere{<0.0, 1.0, 0.0>, 0.4, 1.0 translate 10.0*(ii / nbS)*x rotate
nbT*360.0*(ii / nbS)*x}
#local ii = ii + 1;
#end
}
}
David.
