Someone smarter than me should add a small gas powered altrinator to one of these electric flyers like the Jetson 1, that way you could get more Tham a 15 minute flight time. It makes no sense to pay 100 thousand dollars for a flyer with a 15 to 20 minute flight time. Electric toys are still charged on the ower grid, and here in the U.S. the grid is mostly powered by coal so they are not as green as you all think.
