Several people have been asking about the ability of a wing to generate lift when upside down. The answer is yes, an upside down wing will create lift if the angle of attack is high enough. Now being in a rotor configuration further complicates…
"Gary,
Thanks for your comment. I am going to make a post about the stability of the VTOL flipped wing next. There are some stabilizing factors inherent in the design, such as dihedral in both HALE, and VTOL mode. Additionally, the motors are…"

"The inspiration came from several images I saw of 1950s era clipper ships imagined without tails.
As for the prop location design change...
I was looking for a way to move the props more outboard tin increase the moment they have on the wing…"

"Thank you for the videos. You are right about the spin stabilazation. There were a lot of issues noted on the first test flight. A revised design will be ready to fly next week. Notes on the revisions are linked below.…"
"So that was the bondo mess I was talking about. Also, a word to the wise - you can't bondo over styrofoam, it will dissolve leaving you with a smelly sticky, peanut-buttery mess. The firts wing molds were ruined but the second ones used that tape…"
"I have completed the airframe design and tools. The tools are fiberglass and bondo, but they did the trick for the carbon layup. I used a male mold and vacuumed the carbon on. The surface needed some finishing but came out pretty well. This is…"
"I like this concept as well. The aircraft mode could be greatly improved upon. There are many well developed flying wing designs that would be suitable. The major challenge is with the control of the helicopter mode.
The lack of control in…"
