Can anything actually stand on those?
well you can just bout latch one chap on the back... good for unit recognition. though in terms of how they actually work, i tend to imagine that the passengers would be holding onto the vehicle suppoted on the flat panels or between the blades... of course, all manner of eldarish high tech alternatives couldalso be employed... such as gravity fields (linked into the harlies own flip belts)...
Ultimately though, i wanted to create something that merged eldar and dark eldar to give the look and feel of both elements. It also had to be very sleek and streamlined (which is why i opted against using the DE gantries)...
