New Atlas<\/em>\u00a0(formerly Gizmag)<\/a>\u00a0alerted your editor to\u00a0this\u00a0<\/a>web site, which in turn features\u00a0over\u00a0a score of YouTube videos on this fascinating project in Sweden.\u00a0 Axel Borg has created, as promised by the\u00a0web site, an Amazing DIY Project, flying around a hilly woodland on the power of 76 electric motors.<\/p>\n

Undaunted by Fuel Fumes or Crashes<\/h4>\n

More amazing, perhaps, he tried this configuration a year ago with eight internal combustion engines (extremely noisy), but managed to crash that.\u00a0 Resisting the fear that would instill in queasier souls (your editor, for instance), Axel made four tubular rings, within each of which is mounted a set of 19 motors.\u00a0 The four rings surround the pilot\u2019s seat,\u00a0under\u00a0which are mounted four battery packs \u2013 each one supplying a set of motors with power.<\/p>\n

Axel has apparently done a good job of managing the control of the machine, showing in several videos his ability to maneuver in\u00a0roll, pitch and yaw, and describing how he\u2019s programmed proportional and integral (PI) settings in the controllers to a point where he\u2019s pleased with the results.\u00a0 All the flights so far, and for the immediate future, are purposely kept at a low level.\u00a0 Axel reports, \u201cI\u2019m not flying higher since I do not believe in reincarnation.\u201d<\/p>\n
