Good luck,you’ll need it.Everyone knows flight by intelligent design requires two rotors and much spewing of hot gases to overcome the gravity caused by the flatness of the earth.
I'm flying a Ximango motorglider, so if you count each prop blade as a "rotor", that requirement is met. Usually only takes about .2/hour on the fossil fueled thermal to get 4-5 hours engine off on a good day. So, I don't think that meets the criteria of having to spew hot gasses to overcome gravity caused by the flatness of the earth. I am using hot gases to stay aloft, though. Maybe that helps? I find that the lift is really, really good up near and around Carthage, TN, too......lots of hot gas being emitted in that area thanks to the Profit Owl Gore....
