Is DJI Mini 3 Pro Waterproof- Can You Fly it While it is Raining?

DJI Mini 3 Pro

DJI Mini 3 Pro is definitely one of the best drone I have had my hands-on, DJI have come a long way since their previous versions of the mini line-up and naturally, people want to know if it has achieved what other drones have been able to achieve like I saw someone ask can it record sound, and is it waterproof?

Just like every other DJI drone, DJI Mini 3 Pro is not waterproof and it is ill-advised flying it while it is raining. DJI also recommends avoiding flying in high humidity and foggy weather as precipitation might cause a short circuit making the drone inoperable and causing it to crash.

For something to be called waterproof, it has to be fully submerged in water and stay fully functional afterwards, so technically speaking DJI Mini 3 Pro is not waterproof.

However, no one is trying to go scuba diving with their drone most people just want to know if they can fly their drone while it is raining, or want to know what happens if their drone landed on water accidentally right?

So in that sense, we can say DJI Mini 3 Pro, like most drones is water-resistant to some degree.

Anyways to avoid complications we can stop using vague terms such as ‘water resistant’ and ‘waterproof, and instead talk about IP ratings.

Drone IP Ratings

A high IP rating implies the motors are fully enclosed, and the internal components are protected against dust and rain, Which is important if you’re looking to fly your drone in rain, near water bodies with strong turbulence, or in any situation where weather conditions might change quickly.

so where does DJI Mini 3 Prolay on the IP scale, answering that with a number can get me into trouble, so I will leave you with the next question-

Can you fly DJI Mini 3 Pro in the rain?

According to DJI, you can not fly drones while it is raining, however, manufacturers like to play safe and tell their customers far below what their product is capable of, to avoid complications and lawsuits.

I have been able to fly different drones from different companies in heavy rain drones from phantom 3 and spark to Mavic 3 and so did 100s of other people you can watch on youtube.

Now when it is raining, the vent of the drone is what makes it vulnerable to water damage. This vent is what allows drones to breathe to prevent overheating, but is usually the weak link.

But thankfully the vent is not on the top of the drone, it is usually located on the front side just like cars, and can be under the drone.

Depending on where the vent is located the angle at which the rain falls on the drone has a significant influence.

On DJI Mini 3 Pro the vent is in a very vulnerable position, it is located on the top front which makes it prone to rain damage

In what kind of situation is rain likely to go into your drone?

  • Strong wind– If there is a strong wind, raindrops will be scattered into much smaller water particles, on top of that they will be blowing at a more horizontal angle. For instance, a drone that is rated ipx2 will be able to handle a light shower but in windy situations, even light showers become dangerous because the water particles will be going sideways.
  • If the drone is flying at a high speed– Flying a drone at a high speed is just like when there is horizontal rain because your drone is going at a certain speed it will hit the raindrops.
  • If the drone is flying at a steep angle to the rain– drones are the most vulnerable when flying at a steep angle to the rain or in other words when decreasing altitude at a high speed or doing stunts by flipping the drone upside down.

So if you want to fly your drone while it’s raining, you want to fly it at a low velocity and when the wind is calm, and you should never try stunts while it’s raining!

What are the challenges when flying a drone in the rain

Besides the fact that you are risking your drone to water damage there are several other challenges if you want to fly your drone in the rain

Keeping your drone in Visual Line Of Sight

When operating sUAS (small unmanned aircraft system) Federal Aviation Administration, keeping them in VLOS at all times.

VOLS(Visual Line Of Sight), is typically 500 meters from the pilot, and it significantly decreases in harsh conditions such as heavy rainfall, and hail, which can make it difficult to operate UAVs.

*Note: never use fpv while it is raining!*

Electrical components

If Precipitation gets inside a drone mid-flight it can ruin electrical components, such as the motherboard electronic speed controller or the power distribution board which is often on the motherboard which can lead to a crash.

Water can also cause corrosion in the long term which can damage the drone irreversibly.

Vision sensors

Most drones have sensors, the ones that can be affected by rain are vision sensors. vision sensors are optical sensors that help with stabilization and obstacle avoidance.

When it is raining the sensors are not able to function properly which makes it hard for both the drone and the operator to fly the drone properly.

Legal issues

There is no law against flying in rain in august of 2021 which is when I am writing this article. however, FAA might do it in the near future

Even though there is no law against flying in the rain, F.A.A advocates operating in a careful manner and it can be considered as a careless thing to operate a drone while it is raining.

Not only that but if water gets into your drone it can cause a short circuit(A short circuit is when current travels along an unintended path with no or very low electrical impedance), if that happens your drone can fall from the sky just like a brick and that could cause problems to the point where it can cause property and/or physical damage and/or complicated legal issues.

Controller safety

If you fly a drone in rain it is best to keep the controller out of the rain because if the controller gets damaged it can lead to the same results which is a crash

How to waterproof your DJI Mini 3 Pro

Even though you can not completely waterproof a drone there are 2 popular and somewhat effective ways drone pilots use to prepare for operating in rain.

The first and the easiest is by using a wetsuit to cover sensitive parts.

Neoprene Wetsuits

Wetsuits for drones are becoming more and more popular drone enthusiast community. If you haven’t seen one before they are just like the ones people use for diving but for drones.

I personally am not a big fan but I have tried them on a couple of my drones and I have been able to safely fly in light rain quite a few times.

However, they are expensive and you should also understand they are not going to waterproof your drone completely they just cover some sensitive parts such as the battery

The second which I would say is better is by using a silicone conformal coating.

Silicone conformal coating

Using silicone conformal coating is the safest way to waterproof electronics.

waterproofing drones with a silicone conformal coating is very easy, however, by doing so you can void your warranty.

anyways what you do is remove the battery then remove the frame then apply a thin layer of Silicone on every circuit board then just like that you are good to go for months.

Does DJI even make waterproof drones?

DJI does not make any waterproof drones except DJI Agras and DJI M SERIES, and they are both made for different applications.

The reason DJI does not make waterproof drones is that it is essential for a drone to have a venting system and with a vent there is an opening, with an opening there is a way for water to go in.

However, in my opinion, Some drones from DJI such as Phantom 4 and the new Mavic 3, have a good level of water resistance.

Mavic PRO 1 and 20
DJI Phantom 4maybe?
DJI AgrasIP54
DJI Mini0
DJI FPVUnspecified
Mavic 3Maybe/ maybe not?
DJI Mini 3 Promaybe not

Unspecified doesn’t actually mean the drone has zero protection, it means DJI will not be taking responsibility for any water damage.

If you were to ask me to rate phantom 4 or DJI Mini 3 Pro on the Ingress Protection scale I would give them more than ip32 but don’t quote me on that it is just an opinion.

The rest of DJI drones can not be flown in rain at least according to DJI, especially Mavics.


can DJI Mini 3 Pro fly in snow

It is not recommended to fly DJI Mini 3 Pro in snow, as snow has the same effects as water and can damage the internal components if it goes through the vent. It is however safer to fly in the snow than in the rain.
