A great way to make sure your drone lasts a long time is to waterproof it. Waterproofing your drone will come in handy in a number of situations, but there aren’t as many ways to do it. We’ll go over a number of techniques in this post to make sure your drone is water-resistant or waterproof.
Why should you waterproof your drone?
First of all, why would you want to waterproof your drone? There are instances in which flying in the rain or snow is necessary, even though as a pilot you should never do so unless you have permission to do so or an emergency arises. We think that’s good enough justification to waterproof your drone! If not, moisture may gather within, on top of, and around the drone, which may cause a malfunctioning light of some kind.
Although this isn’t a major concern, there is also the possibility that moisture will get on the camera and contaminate a shot. Once more, not a major issue per se, but a problem nonetheless. Another scenario in which waterproofing your drone comes in handy is when you’re flying over water, perhaps landing or taking off from a boat or an island. Even with the engine off, there is still a chance that the drone will fall into the water, so you should first make sure the boat is motionless.
For this reason, the wind has the potential to push the boat in different directions, resulting in the drone landing in an unexpected place or even in the water. When waterproofing a drone, the best course of action for a pilot is to look for any potential entry points for moisture. It is possible to waterproof places like the engine, propellers, battery compartments, and more.
Regretfully, you may want to avoid waterproofing your drone if it has ventilation holes. Your drone may overheat and experience burnt circuits, flight issues, and potentially an exploding battery if the ventilation holes are clogged. Positively, some modern drones do not even have ventilation holes on their main body. You can choose to waterproof the drone by placing the majority of these inside the battery.
Waterproofing methods
Spraying and brushing
You can purchase specific brushes and sprays to waterproof drones. These are usually designed for waterproofing shoes. This gloss spray will cover any surfaces, like a gimbal, that have tiny holes in them.
Filling in holes
You could also repair the drone’s rotor holes, but this is a more permanent and riskier solution. This is where the propellers are located. This filler is a permanent solution because, once set, it will make it difficult for your propellers to come out.
The ultimate waterproofing
The primary objectives of this guide were to help drone owners like you strengthen the water resistance of your equipment and to go over some basic knowledge regarding drones and water. Most likely, you are aware of the advantages of waterproofing your drone. You can preserve its electronic components and extend its life at a minimal cost.
Even though a wetsuit is the easiest option, you should have understood the fundamentals of conformal coating and realized that it might not be the best choice. You can achieve the highest level of waterproofing by combining silicone coating your PCB with anti-corrosion on vulnerable ports.
