  • I’m pretty sure I’ve seen small (i.e., handheld-sized) commercial UAVs that fly like this. But as others have pointed out, at any realistic size you start to run into a lot of problems:

    • The VTOL rotors will create massive drag when they’re not in use. There’s a reason virtually every aircraft with embedded VTOL jets engineered ways to cover them up during level flight. This cascades into a whole bevy of complexity issues.
    • When you’re not using them, you’re lugging around 3 out of your 4 rotors for no reason.
    • You’re also sacrificing a lot of internal volume for your lift fans. This isn’t so much a problem in small UAVs, again, but it’s not great if you were hoping to use that capacity for fuel or cargo.

    So yeah, like others said as well - now that we have tailsitter drones of moderate size, there’s not really a use for this layout.
