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.

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

it was made for having fun and for show, not for breaking records!
definately not my fastest prop. but the must unusual.
will look very cool in front of harpyoe or peregrin or big typhoon.
may be also with 11x20 blades on it.
and will be good enough to get minimum 100m/s with an unbelievable noise and also fast climbing.

there is cold and snowy outside, in flight tests have to wait untill next spring.
but it will work - as the 5 blade 11x20 and 12x24 have worked just this year.

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?
