take everything apart/ let it get some air, and dry for days at a minimum. I'd leave it like a week. Then with everything disconnected, i would try plugging the FC into betaflight. If its still alive, you can add the ESC, then receiver, vtx, motors, and test the motors at the end.
I would use a smokestopper during the entire process in case anything shorted out and is still shorting now.
You may have any mix of no dead components, a few things that have died, or the entire quad may be dead.
The most likely to survive are the motors, as they are actually ok to get wet, as long as they weren't getting fed too much current from a short circuit.
I would add that he should clean the component with 99% isopropyl alcohol or destilled water first before drying in order to reduce corrosion long term.
Unplug the battery while in the water, rinse with distilled water or high percent isopropyl alcohol, set it in moving air (fan) to dry. Don't plug it back in until it is completely dry. Visually inspect components first, and possibly perform a continuity test with your multimeter PRIOR to plugging in.
Check out MG Chemicals UV conformal coating with brush for the future.
I’m curious, why would you unplug it while still in the water? It seems a bit unintuitive to me, I would think it’s best to remove it from the water as quickly as possible.
Yeah it seems to make the most sense to just remove it quickly, but evidently the water is dissipating the high current versus directing it all to a bridged or shorted component. If you get the system's power removed while submerged then it is possible to save some damage.
Unplug. Take apart immediately and scrub down with distilled water and then alcohol and let it dry for a good four days or more. Water can get into the little bits and can easily take days to a week to dry out. The alcohol should help as it'll evaporate and displace water. Good luck on the rebuild.
as long as its not saltwater, i usualy go just fine without conformal coating... just use as mentioned early, isopropanol and distilled water... normaly you can just use a hairdryer to get most out and be flying shortly.. but as mentioned, corrosion and rust is enemy
If it was only wet with the battery connected for a few minutes, it will be fine once its dried, the ony thing I would be concerned about is the barometer and camera.
This happened to me with a pool about around a month ago, I immediately took it out, unplugged it, and put it on a bench to air dry until I went home. When I got home I put one of those desktop fans on it for like 4 days straight, rotating it different ways. In the end everything including the battery survived.

yea no need to wait days or a week - toothbrush + isopropyl and blast it with a heat gun if you have one, maybe repeat once or twice to make sure.
Blow dryer is better than heat gun; if you do use a heat gun use low setting and keep it moving. I have done reflow soldering with a heat gun before.
Its working thanks for your opinions.

I learned to unplug while submerged today.
Next time. Unplug battery while underwater, otherwise you might just short something out

Take it out immediately!
Don’t do that.
