Crash my kwad last night and been on the hunt for it this morning and found it am so happy..So been around 8hrs upside down and has rained over night.
Question is...Do I dry it out? then is it safe to unplug or just unplug straight away.
That feeling when u find it is mega well happy as it was my first build..

Some people say to unplug the quad underwater, but yours hasn't been fully submerged. If it was me I would just dry the connectors as well as possible then unplug it by pulling the connectors far apart from each other, quickly. That is what I would do anyway.

Thanks Snowleopardfpv for your fast response ??Will dry it out as you say not been under water,so should be fine.I crashed the same kwad last year in the snow and it was dripping wet the and after drying it, unplugged and it was fine.

Thanks again

give it a weak to dry if you can, unplug all connectors for good drying

I would un-plug the lipo and dry what you can of the quad, then stick it in a bag of rice. The rice will absorb any moisture. Or buy some desiccant, like silica gel beads and use that in stead of rice.

For a board that was exposed to water I would bath in isopropyl alcohol. It will help displace the water and also dry it out.

Skip the rice when it comes to electronics and water damage, it's not going to be proactive enough to help.

I have used this in the past to dry things out:

Works great, and it's reusable. You just put it in the oven to dry it out again and reuse it. Also changes color to let you know when it has absorbed moisture.

I was just recommending rice to help as most people don't have silica desiccant sitting around, but almost everyone had rice. A hair dryer can also help, or just stick the quad in a warm dry place like a linen closet.

I would check your lipo. I made an emergency landing and had to go back the next day to retrieve in daylight. It was still beeping but had drained my new lipo down to nothing. The cells became very puffy and I'm afraid to charge it now. I guess loosing a 43.00 battery is better than losing a 1000.00 quad right?

"Some" minor puffing is inevitable, especially >100 cycles. > 20mohm and I retire packs. Never had to deal with submerged.. yet.

I only fly down to 3.7V.. 3.75V after resting a minute.
If 1 cell is over like 0.1V lower, I remove it from pack.(Dangerous!)

This battery was maybe use 25 times and had no puff until left plugged in over night. It’s got a real bad puff to it.. it’s still on the front porch and is sitting at less than 1v on a 6S 1800.

When it comes to damaged/puffy lipo batteries, I don't take any chances. Even the most expensive quad lipo in the world is worth nothing compared to my house.

Personally I would just put it on my charger and discharge it as low as you can, then put it in trash.
