Thanks, I missed that (I have to say I never even bothered looking; I've seen this kind of website before). It's pretty sparse on information. I managed to find that: - they use lithium ion batteries. - they use LEAPTech style engine layout with multiple small engines (they don't name check it, I just recognise it from https://www.nasa.gov/content/experimental-wing-tests-electric-propulsion-technologies https://www.nasa.gov/content/experimental-wing-tests-electri...). - there's a backup parachute. - they don't mention autonomous flying, but you also don't have direct control of the vehicle --- a computer mediates. - for some reason they insist on calling ducted fans 'electric jet engines'. That's about it. Anything I missed?
