I look forward to electric airplanes, this looks like an impressive contender, and I would like to know more about it. For one thing, I see this is being flown without an occupant. Is it carrying ballast equal in weight to a person, or is it merely carrying sufficient ballast, mounted well-forward, to put the CofG within limits? And is it carrying sufficient batteries to give the quoted 100-mile range? What is its operational ceiling?
