But you use spend much less energy fighting gravity.

I’d expect it to have more range underwater than a typical quadcoter has through air. And much longer “flight” time.

But I doubt it gains enough to compete with a fixed wing drone using the same battery.

I would expect the opposite, with the higher drag being much more of an issue than gravity. But I would be interested to hear a definitive answer.
