Tobbe,
You could possibly use 2 of the Technic 3 bladed rotor parts, rotated 180
degrees from each other. This gives 6 blades, but 3 of them are set back 1
plate's depth. You could possibly build them up a bit to be even.
The Technique 3 blade rotor part looks like this:

Use indeed 2 Technic 3-bladed rotor parts, put on each blade 3 Technic
half-beams (with rounded ends) and put the rotor parts on an axle, face to
face, turned 180 degrees.
Voila, plain and simpel, all propellor blades in line, further enlargements as
you wish.
Need more info? Mail me for a simple instruction-picture, with 'blades' made
of 7-holes half-beams. (in terrible colors !!)

Et voila indeed!
Hope I had the eight 3 blade rotors needed, do they come in black? I
have to see if I can find a good source for them. Se my other answer
in the original thread for my latest idea.
Thanks!
TGIF!

I've noticed that 1x plates attached to the holes of a 6 hole pulley don't
move around very much. So to make a propellor, (with 3 blades offset by one
or two plates), attach 3 1x plates to a pulley so they stick straight out.
Do the same on another pulley. Put the pulleys on an axle, and you've got 6
plates extending from a small hub. Attach some 2x plates creatively, and
you can even get rid of the offset.
