As I wrote I used the #20 / #21 panels. That is the panels that comes with
the Williams F1, the other has a big hole in the midle and are too bulky. I
testet both and got far better lift with the Williams F1 panels. But i dont
have those panels in Ldraw so the image I made was just for you to get the
idea how I done it.
> how do you prevent tilting pannels in the oposite direction to air flow?
The panels holds itself in the raight direction because the blades tuch the
the Technic Angel Connector #2 at one end. The propel was not made by me
thinking out that solution before building, I like to "think" with my
fingers and the parts. Just take a part, look at it, take another part, hold
them together and see if they fit or I can use that, if not try another
part... well, almost like that :)

Well, I have tried the prop without the hovercraft skirts (the plastic
cladding around) and I got lift when I had enoug power, about 11-12v DC
(tried with an adjustable power source).
So if you find a powerfull enough motor it can be used as an helicopter or
plane prop.
