Drones are expensive toys and important equipment for businessmen, you can’t afford to get them wet. Water and an Electronic device doesn’t mix well with each other, so it is unlikely that an operator will fly near water. But as we all know, accidents do happen and they cost a lot of money. Here is what you need to do if your drone is water damaged.
Safety Is Most Important
This advice doesn’t concern drones; it is for you. Don’t jump in water just to save a bundle of electronics. Don’t think about investment, you could be endangering your life. Spend short time to think about possible ways to retrieve it safely, or recover only if it’s worth it.

When your drone hits water, there is a possibility that Electronic Speed Controllers (ESCs) will blow. One is connected with each motor and sometimes it is integrated into them. Quickly switch off power and remove battery. If there isn’t a separate on/off switch on your drone then just take out the battery. See if batteries are damaged, and if they are, put them somewhere safe.
If it Crashes in Salt Water
Don’t crash your drone in sea water, consider it a universal rule. There are corrosive and conductive elements in salt water. In case you accidentally drop it, dunk into fresh water and rinse it. Distilled water don’t have chemicals in it so it is preferred. Fresh water is much better than salt water – Even tap water might have some chemicals.
If Motors Get Wet
Use a cloth to dry water from exterior and check if there is water on it. Drone motors aren’t affected by water because they are brushless and mainly rely on magnets rather than brushes and commutator.
If you have warranty, there is nothing you can do except putting it in a warm and dry place until you can send it to the supplier. Don’t unscrew the top of your drone, your warranty will be nullified. If you think the crash was due to a fault then supplier will look into your log and see if there was product failure or pilot error.
Water Proof drones
There have been many attempts to make drones water proof with the help of Liquipel – a system used for tablets and mobiles. There isn’t a definite evidence but many videos on the internet claim it is successful.
If you have to fly over water
It is easy to avoid flying near water, but if you have to, then pre-check the aircraft and area where you want to fly. Insert a fresh pair of batteries and don’t allow a margin of error when bringing it back. Your drone may have to battle a strong wind when it returns home. If batteries are at low or critical stage then it will land on the water. If you want to avoid it, make sure to check everything before flying.
