Probably, I've testet your fan construction now, but I'm not sure that I
made it correct because I have a hard time getting the blades to stay in the
right angel.
When rotating they go back to horisontal angel...

Well, the tunnel is necessary, but just in the right place. I've got the
blade turning inside the tunnel. Infact the blades are so close to the wall
of the tunnel that I can sometime hear they are tuching the walls.
The blades bends a little when going for full speed, and when they bend the
diameter of the fan is getting larger...
But the tunnel on the steering fan have to be improoved. It is a little to
small (just missing a few millimeter). And it also has to be a bit longer
since the fan now is mounted behind the tunnel, but should be mounted inside
the tunnel to get the best effect.
The tunnel has to be smooth on the inside too so I put plastic film on there
too.

Maybe I dont need them? I have not tried without.
I thougt they helped shape the outer rim of the skirt.... it has to be
shaped like an
(``````````), bending in under the craft. Maybe they can be shorter or made
flexible... more flexhose ... ideas are streaming in my brain now... :)

Well, I do need a better skirt to get it to fly over obstacles....
How did you construct your outer rim of the skirt?

I have three rings, maybe the middle one can be removed...

hmm... good idea. I'll try that too.
