first benchtest with about 8.000 watts was okay (was only the small 4235 sized motor)
reached 13.200 rpm without problems.

afaik stefan still has some of these crazy middle parts available.[/QUOTE

great work done
I like it :-)

What the holy !!! Ralph why you tease us with such killer-pics :'(.... Thats unfair.
Middlepart and prop is availlible but no motor (((

I wonder if the blades have variable pitch?

Reckon an 8 blade sawtooth would look pretty cool

Really nice work man, will we be getting a video?

scorpion-fan , how is the performance/thrust/pitchspeed when compared to 6/4/3/2 blades, whats the curve: rpm, thrust, efficency ? is there any, Im very interested in that sort of comparison with same blades but only difference is how many of them..

Idea is cool but I think they explode at the power needed for this setup to be fast. And for an 8 blade setup u need plenty for sure. But the looks would be killer

I think it might be something worth experimenting with regardless. It may not break speed records due to max power limitations but It would be incredibly quiet and efficient. Possibly something for UAV's.

Whats the chances of getting one of those yokes?

Just pm Markus Koch he can help you for sure .
Ralph you have to post more videos . That should be your New Year's resolution
