Without Marcy 1, there would be starvation. The Marcy Mogul is insane, but when you need to pay the rent & she's the only way, there's no more budget for argument.

With rare access to a larger room, these aircraft have done some pretty impressive flying with preprogrammed horizontal translation & ground based vision. There are lots of problems with ground based vision & control, but when it works, it works.

The control problems definitely put you off of ever selling it as a product, but there is hope that the problems are manely with position sensing rather than the airframe design.

Not sure how you can get what I see to fly. I have seen one winged fliers, but normally there is more lifting surface. Interesting minimal concept, but I would want to see how it performs before trying to make one.
