RE: BTE Delta Vortex Construction Photos
I think that the DV would electrify easily. Light wing loading and humungous interior volume would make it easy to carry batteries. The initial expense would be a toad-kicker, but it would be a neat project.
Another idea would be a glow-powered Ducted Fan unit mounted topside between the fins.
I'm planning a DV once I get a 3-plane backlog taken care of....
