You both in Maryland? My brother lives there! 😃
I've contemplated sticking a pair of wings on a quad to make it more efficient for longs flights, but figured racing quads aren't really about efficiency. Making it tip over 90 degrees is something I didn't consider though, but as you have demonstrated it needs a bit of extra programming. Still these bi-plane props look very Star Wars, makes me wonder what other wonderfully weird models you could make around this concept. Bit unrelated, but this idea doesn't really belong anywhere currently; I have contemplated an idea for a kind of induction fan & Nozzle 'quad' that I could hide inside a spaceship. Someone on youtube made a Harrier that runs on a single EDF so I'm wondering if my idea here is possible: Where I'm lost is how to program a flight controller to manage the thrust on each nozzle. I've considered servo-managed shutters inside the pipes to vary the thrust.
