The monsoon season transforms Kerala and Goa into lush green paradises—but flying FPV drones in this season comes with unique challenges. Whether you’re filming waterfalls or chasing waves, it’s crucial to monsoon-proof your FPV drone to avoid crashes, corrosion, and costly repairs.
Risks of Flying in Monsoons
Monsoon weather isn’t just about water—it brings high humidity, gusty winds, and electrical interference. Here are the key risks:
- Motor Corrosion: Rainwater and moisture can oxidize motor windings and bearings.
- Signal Loss: Clouds and rain affect FPV transmission and GPS lock.
- Short Circuits: Water can seep into ESCs, flight controllers, or VTX systems.
- LiPo Battery Swelling: Dampness can degrade battery integrity.
Top 3 Monsoon-Ready Drones (with IP Ratings & Prices)
If you prefer ready-made solutions, consider these FPV or cinematic drones with higher water resistance:
- DJI Air 3
- IP Rating: Water-resistant (unofficial)
- Approx. Price: ₹1,09,000
- Why: Dual-camera system, active obstacle sensing, performs well in humid conditions.
- SwellPro Spry+
- IP Rating: IP67 (fully waterproof)
- Approx. Price: ₹1,20,000
- Why: Built for marine and rainy conditions. Floats on water.
- GEPRC Cinebot 30 (with conformal coating)
- IP Rating: None (DIY coating required)
- Approx. Price: ₹45,000 (BNF)
- Why: Lightweight, great for close-range flights in drizzle after waterproofing.
DIY Waterproofing with ₹500 Kits (Step-by-Step Guide)
You don’t need to spend lakhs. You can waterproof your drone using affordable materials:
What You Need:
- Silicone conformal coating (MG Chemicals or local brands)
- Small brush or dropper
- Isopropyl alcohol (for cleaning)
- Electrical tape or liquid tape
- Plastic film for LiPo protection
Step-by-Step:
- Disassemble your drone: Expose the flight controller, ESC, and VTX.
- Clean components: Wipe surfaces with isopropyl alcohol.
- Apply coating: Brush a thin layer over the circuit boards (avoid connectors).
- Dry 24 hours: Let the coating cure before reassembling.
- Seal ports and gaps: Use liquid tape or insulation.
- Wrap LiPo: Use zip bags or shrink wrap to protect batteries.
Tip: Avoid coating ESC pads and USB ports. Cover them with masking tape before coating.
Post-Monsoon Maintenance Tips
Even with waterproofing, regular maintenance is crucial:
- Rinse motors with distilled water if exposed to salt or muddy water.
- Dry with compressed air after every wet flight.
- Check for rust on screws, bearings, and motor bells.
- Balance LiPo voltage after each flight and store at 3.8V per cell.
Best FPV Spots in Kerala & Goa During Monsoons
Here are some epic, relatively safe places to fly during the rains:
Kerala:
- Athirappilly Waterfalls – [10.2843, 76.5741] (fly from high ground, not near falls)
- Wayanad Hills – [11.7150, 76.1349] (low wind mornings ideal)
Goa:
- Chapora Fort Viewpoint – [15.6010, 73.7354] (watch out for wind gusts)
- Tambdi Surla Forest Edge – [15.4272, 74.2031] (lush and cinematic)
Final Thoughts
Flying in the monsoons isn’t just possible—it’s epic when done safely. With a little DIY waterproofing and smart planning, your FPV drone can capture some of the most dramatic, cinematic shots nature has to offer. Stay dry, fly smart, and respect the environment around you.
