I built the only solely ion propelled aircraft that can carry its power supply onboard. It can fly vertically or horizontally for nearly 2 minutes, so far. I'm still finishing up the stabilization and steering but it works. See US Patent No. 10,119,527, or the videos etc. at url deleted I share a lot of data on the subject that I picked up over the past 19 years on the site. Just a heads up, a lot of the literature on the subject is wrong. That is why people are not getting better results. A lot of the misconceptions are clarified, at least implicitly, on my site and patent. I hope you find this helpful!
Best regards,
Ethan
