Can drones fly in the rain?

Drones are fun to fly. In today’s world of technology, they can be considered as one of the greatest inventions. Drones can take pictures, capture stunning videos, make deliveries and take you to the places where it was impossible before. There are a lot of manufacturers out there that produce drones loaded with tons of features. These drones are designed to meet different consumer requirements, but can they fly and survive in adverse weather conditions? For example, can drones fly in the rain? This question often comes to mind.

Generally, drones are not designed to withstand against rainy conditions, because they are neither waterproof nor water-resistant. Motors and other electrical components are critical parts of the drone and water can easily destroy them. So, if you are planning to take your drone out in the rain and test some technical possibilities, you need to consider many factors. On the other hand, there are some aircrafts specifically made for the people who want to have fun in rain.

Things That Can Happen to a Drone While Flying in Rain

If you have finally decided to fly your drone in the rain, then this may not be the possibility that you are going out to take some photos and videos. Because the camera lens won’t be able to deliver the results with any clarity once it gets the rain drops on it. If you feel, there is a chance of rain in weather forecast; it will probably not be a good idea to go too far from your home and fly. If it starts raining, turnaround and fly back home, as you still have a chance to prevent the rainwater from getting into your drone. And when you recover the drone, shut it off instantly and take the battery out. In case of light rain, your best course of action would be to remove the battery out of the drone and leave it somewhere in a dry place for some time. And if your drone got soaked in case of a sudden heavy rain, you need to immediately remove the battery and don’t put it back in the drone again as this water-drenched LiPo battery might have gone bad and you can’t trust it anymore. Now leave the drone in the sun to dry for maybe a couple of days before switching it on. Remember; don’t try opening the drone as it will deny your warranty claims.

So there are numerous components of a drone that can be damaged by rain water. The area around the gimbal is not completely sealed off and water can easily penetrate through. However, motors can be somewhat protected due to spinning of the props, still they won’t last long; and if the water gets into the electronic speed controller, your drone will be falling out of the sky as it may cause short-circuiting. This short-circuiting can damage the electrical components on circuit board and melt the cables inside, or rotor and stator of a motor may end up welding together.

If the water flows in the flight controller, it will connect the positive and negative poles and there can be a problem for you to control the drone also.

Short-circuit is not the only reason that can lead to a drone crash. If you are flying a fixed wing drone, too much raindrops on its surface and wings not only disturb its flight characteristics but also slow it down. This effect is not so strong for the rotating wing quadcopters but still the drones which don’t have much power, water on their surface should not be underestimated.

Visibility is also an important factor to consider when flying in rain. If you are flying the drone where you can’t see it, you not only risk losing it, but also put others in danger. So it’s better to keep it in sight and if it goes away, just press the “come home” button immediately.

Effects of Humidity and Fog on Drone Flight

As far as humidity is concerned, first thing that comes into mind is that the exposure of a drone to the mist can be a problem, but it’s not the only case here. Humidity can make a radio signal weak because it causes interference. This is because high frequencies have shorter wavelengths and the possibility of hitting water droplets increases in humidity and rain. Water molecules absorb some of the energy of the radio waves. So, humidity factor can affect your signal at long ranges.

Fog also has the same effects on flight performance as humidity. If you have been flying in fog and your drone didn’t sustain any damages just yet, despite being covered in water coat, then it was very fortunate for you. For instance, a drone pilot was describing his experience of flying a Phantom in fog and he ended up losing three of its motors after some days. So, fog should be taken seriously, although, it may not be as unsafe as rain is, but before you set out to fly, it would be a wise decision to check the forecast first. Another issue with the fog is visibility, and as we all know that FAA does not allow you to fly beyond visual line of sight.

Effects of Cold Temperature on Drone Flight

Cold temperature can also impact the performance of the drone. It decreases the chemical activities in the Lithium Polymer battery, which is usually installed in DJI drones. Decrease in temperature can significantly decrease the flight time. Before you plan to fly in cold temperatures, you need to ensure that you have followed below steps recommended by DJI.

  • Make sure your battery is fully charged.
  • Pre-heating can improve the battery efficiency. Battery heater can be used for such purpose. Keep the battery temperature at 20ᵒ or more. DJI GO app can be used to check the battery temperature.
  • Let the drone hover for at-least a minute to warm up the battery.
  • Voltage drops can be avoided by gently pushing the sticks on the controller.
  • Keep checking the battery status while flying.

Effects of Snowing on Drone Flight

Generally, there shouldn’t be any problem when flying a drone in snow but you need to be extra careful before doing so. Use some protection to cover the contacts of the battery and clean the snow from the drone body. When you retrieve it after flying, clean it immediately from the snow again with some dry cloth before it melts.

How to Differentiate Between Waterproof and Water-resistant

As aforementioned there are some drones that are water-resistant and waterproof as well, so before we list them it is important for you to know the difference between the two.

Something that prevents water from getting into it for a short period of time can be labeled as water-resistant, it is not waterproof. So, if you encounter light rain during flight, there won’t be any issues, because your drone can handle it but don’t just stay there and let the rain or snow penetrate into your aircraft, because it can still lead to one of the events mentioned above. So, a drone being water-resistant gives you enough time to react and avoid the possible damages.

And something that is completely shielded and does not allow the water to pass through it – is known to be waterproof. Waterproof drones can fly in rain and if they fall in the water or lake, just take them out and they are ready to fly again. You can submerge them completely in the water. Some of them can also be used for underwater short flights, so you can take them with you while going on a sailing trip or swimming.

Some Waterproof Drones to Fly in Rain

So Can Drones Fly in The Rain?

Rainy conditions won’t miss a chance to damage your drone and it would be better not to launch it in rain if it is not water-resistant or waterproof. In case of a very mild rain, it can somehow be safe to try for a short period of time; however, we will not encourage you to do that either. Rainy conditions also create cold environment, which may have negative impact on your drone’s LiPo battery. In cold and rainy weather, drone motors would require extra power to lift it up and water flow inside the drone could seriously harm the electronic circuitry. Camera and gimbal are also sensitive parts and they may have the same outcome.

If you still can’t live without flying a drone in rain, then you have plenty of options to choose from waterproof or water-resistant drones.
