In this comprehensive guide, we’ll explore the steps to take if your drone falls in water, from immediate action to long-term damage control.
Act Fast: The First 30 Minutes
The most critical period in saving your waterlogged drone is the first 30 minutes after the incident. Time is of the essence, as the longer your drone is exposed to water, the greater the risk of permanent damage. Here’s what to do in the first half hour:
Rapid Retrieval
If possible, retrieve your drone from the water as quickly as possible. The faster you can get it out of the water, the better. If you’re near the drone, carefully wade or swim to it and grab it. If you’re unable to reach it, try to get someone else to retrieve it for you.
Turn it Off and Remove Batteries
As soon as you’ve retrieved your drone, turn it off immediately to prevent any short circuits that could cause further damage. Next, remove the batteries to prevent them from short-circuiting and causing a fire. This is especially important if your drone has been submerged for an extended period.
Drying and Disassembly
Once you’ve turned off your drone and removed the batteries, it’s time to start the drying process.
Surface Drying
Gently pat the exterior of your drone with a soft cloth or paper towels to remove any excess water. Be gentle to avoid pushing water further into the drone’s crevices. Focus on the areas around the motors, ESCs (Electronic Speed Controllers), and any other components that are susceptible to water damage.
Disassembly and Internal Drying
To prevent further damage, you’ll need to disassemble your drone to access the internal components. Use a soft brush or canned air to gently remove any debris or water from the crevices and connections. You can also use a desiccant, such as silica gel packets or uncooked rice, to absorb moisture from the internal components.
Advanced Drying Techniques
For more severe water damage, you may need to employ more advanced drying techniques.
Vacuum Sealing
Place your drone’s components in a vacuum-sealed bag or airtight container with a desiccant to accelerate the drying process. This method is particularly effective for drying small components like circuit boards.
Baking
Caution: This method requires extreme care and attention to avoid overheating your drone’s components. Place your drone’s components in a low-temperature oven (150°F – 200°F) for several hours to evaporate the moisture. Monitor the temperature and components closely to avoid damage.
Assessing and Repairing Damage
Once you’ve dried your drone, it’s essential to assess the damage and identify what repairs are needed.
Inspecting for Corrosion
Inspect your drone’s components for signs of corrosion, such as rust or oxidation. Clean and replace any corroded components to prevent further damage.
Testing Electronic Components
Carefully test each electronic component to determine if it’s still functional. Start with the most critical components, such as the flight controller, ESCs, and motors.
Professional Repair or Replacement
If you’re unsure about repairing your drone or if the damage is extensive, consider seeking the help of a professional repair service or the manufacturer’s authorized repair center. In some cases, it may be more cost-effective to replace your drone altogether.
Preventing Future Water Damage
To avoid the hassle and expense of water damage, take these precautions to ensure your drone doesn’t take an unexpected swim:
Waterproofing and Coatings
Consider applying waterproof coatings or sealants to your drone’s components to protect them from water ingress. There are various products available on the market, such as waterproof sprays and ceramics.
Flight Planning and Awareness
Plan your flights carefully, taking into account weather conditions, terrain, and potential hazards. Always be aware of your surroundings and maintain a safe altitude to avoid collisions or water landings.
Drones with Water Resistance
If you frequently fly over water or in wet conditions, consider investing in a drone with built-in water resistance or waterproofing. These drones are specifically designed to withstand water exposure and can significantly reduce the risk of damage.
In conclusion, while a waterlogged drone can be a stressful experience, there are steps you can take to minimize the damage and potentially save your drone. Act quickly, dry carefully, and assess thoroughly to ensure your drone is back in the air in no time. By following these guidelines and taking preventative measures, you can enjoy safe and enjoyable flights, even over water.
What should I do immediately after my drone falls in water?
When your drone falls in water, the first thing to do is not to panic. Instead, try to locate where your drone went down and mark the area. If you can see your drone, try to retrieve it as quickly as possible to minimize the damage. If you can’t see it, try to estimate the location based on the last known flight path.
Turn off the power to your drone remotely if possible, and do not attempt to turn it back on until it has been properly cleaned and dried. This will help prevent any short circuits that could cause further damage. Also, be careful when handling the drone as it may still be energized, even if it’s been in the water.
How do I dry my drone after it’s been in water?
The key to drying your drone is to act quickly and be gentle. Remove any batteries, propellers, or other parts that can be detached and place them in a dry, well-ventilated area. Use a soft, dry cloth or paper towels to gently pat the drone’s body and components, being careful not to rub or scrub too hard.
Next, use a desiccant like silica gel packets or uncooked rice to absorb any remaining moisture. You can also use a dry, warm air blower to speed up the evaporation process. Avoid using heat guns, ovens, or microwaves to dry your drone, as they can cause damage to the internal components.
Can I still use my drone after it’s been in water?
It depends on the extent of the damage. If you’re able to dry your drone quickly and thoroughly, it’s possible that it may still be functional. However, even if it looks and seems okay, there may be hidden damage to the internal components that could cause problems later on.
It’s always best to err on the side of caution and have your drone inspected and tested by a professional before flying it again. They can assess the damage and determine if it’s safe to fly or if repairs are needed.
How can I prevent water damage to my drone in the future?
One of the best ways to prevent water damage is to take steps to prevent your drone from falling in the water in the first place. Make sure to fly in open areas away from bodies of water, and always keep an eye on the weather forecast. Consider investing in a drone with waterproofing or water resistance, and always follow the manufacturer’s guidelines for flying near water.
Another important step is to regularly inspect and maintain your drone to ensure that it’s in good working condition. This includes checking for loose screws, damaged propellers, and worn-out components. By being proactive, you can reduce the risk of accidents and extend the life of your drone.
