It's interesting how simple this looks, off the shelf parts, and 3D printed components. I'm almost surprised this doesn't already exist after looking at it.
I feel like I've seen some of these before without the variable pitch part ex. https://www.youtube.com/watch?v=jlMDabBfJp0
Very impressive. I assume that underwater propulsion uses a lot more energy per meter moved?
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.

If your mothership is low-observable/submersible you could park it in a harbor and when time is right unleash a swarm of hybrid aerial underwater drones with mission payload. This design uses 1 swashplate server plus 1 brushless drive motor for each prop for a total of 8 motors. Designs in Ukraine are now using 1 brushless drive motor to synchronously drive all 4 props and 1 swashplate servo each prop, reducing total…
Why do the drones need to be able to work underwater? Can’t you just connect some floats to them and launch the drones once they’re at the surface?

You can waterproof regular fpv quads with silicone coating on the pcb. https://www.youtube.com/watch?v=WzUy6Wk86-A
> Hybrid drones offer great potential in many industries due to their ability to operate in air and water. "Hybrid" usually means a combination of features from two different things. For instance, a car with electric & internal combustion engines. But here they are using "hybrid" to mean a combination of capabilities . That's different than features. Also, "hybrid done" already has a meaning: https://en.wikipedia.org…
Looks to me like it is a hybrid of an underwater drone thing and an aerial drone thing, and that you have a good opportunity to expand that wiki page to include the other meanings of the term.
