This is what you get when you cross a quad with a fixed wing. Sure is ugly, but practical.

I didn't once see it fly horizontal like a wing, just a labored slanted forward flight. For me I don`t see any advantage over a standard multicopter with a shelf to carry stuff.
I think it is still pretty much in development but at 1:47 it seems to be in fast wingborne flight slowing down and transitioning to hovering by 1:57.
I like the idea of doing this all by differential thrust, thus eliminating the complexities and potential problems of a mechanical system.
Looks better than some, but , like Coyote would've liked to see it transition from vertical takeoff to high speed forward flight. Prob just a problem of getting the software right!
OTOH its not like its not a solved problem... 40 years ago.. :laugh:

There's something called the Quadshot which is similar and has been around for a couple of years.

Just a little beyond the average model flyers budget. ;D
Mind you, plenty of old airframes available thanks to the wisdom of the Government retiring the fleet early and before the slightly expensive F-35 goes into service.
There is also the firefly y6 which does this and is affordable for modelers.

Not exactly much payload carrying but DIY :
