GE,
Several observations:
1 I'm purely a homebuilder, mostly interested in hovercrafts. I have
an unfinished but operational UH-18sp to which I will probably add the
wings at some point. I've spent some time on the se-technology forum,
so I know the difference between a "proper" WIG and a UH-18spw.
2 Congratulations on your achievements with WIG crafts.
3 The .org domain is supposed to be restricted for non-profit
organizations. You might want to find a different domain name.
4 If you had a 300 hp wig of modest size and it didn't take off, then
you have something wrong with your lifting body. In effect, what you
have here is a 300 hp boat with some extra drag. Those surfaces can
hold you to the water as easily as they can hold you above it.
5 While I agree with you in that power does not guarantee flight, I
will say that thrust does. At some point, given enough thrust, the
vehicle can go straight up without benefit of a lifting body at all.
Any rocket is proof of this. I don't want to go there, it's just an
extreme example to prove a point.
I happen to be friends with the owners and know the employees of the
Universal Hovercraft company ( http://www.hovercraft.com
), which is
why I know as much as I do about the WIG at the end of the UH video.
I go to their houses, go hovering with them, and I'm helping them move
their shop.
Getting back to the main objective here, there are a lot of folks who
want to buy their toys. I'm not one of them. If I can't build it,
I'm really not that interested. Goes for hovercrafts, aircraft,
boats, whatever.
