Field Report: Three Weeks on the Oregon Coast
The Pacific Northwest coastline throws everything at drone operators. I spent 21 days documenting a mixed-use development project spanning 47 acres of beachfront property near Astoria, Oregon. Cranes, scaffolding, ocean spray, and unpredictable gusts created the perfect stress test for the Neo 2.
This field report breaks down exactly what worked, what required adaptation, and the antenna positioning techniques that kept my signal locked at distances exceeding 800 meters despite heavy RF interference from nearby marine communications.
The Site: Challenges at Every Turn
Construction sites near water present a unique combination of hazards. This particular project included:
- Three active tower cranes with constantly moving loads
- Temporary scaffolding reaching 12 stories on the main structure
- Reflective safety barriers creating visual confusion for sensors
- Salt-laden air with humidity regularly exceeding 85%
- Sustained winds averaging 15-22 mph with gusts to 35 mph
The Neo 2's compact form factor initially concerned me. Previous experience suggested smaller drones struggle in coastal wind conditions. Those concerns proved largely unfounded.
Obstacle Avoidance Performance in Complex Environments
The Neo 2's multi-directional sensing system earned its keep within the first hour of operations. Construction sites feature moving obstacles that static mapping cannot predict—swinging crane loads, workers on elevated platforms, and debris carried by wind.
Sensor Response Testing
I deliberately flew approach patterns toward scaffolding at various speeds to evaluate response times:
| Approach Speed | Detection Distance | Stop Distance | Response Rating |
|---|---|---|---|
| 5 mph | 28 meters | 3.2 meters | Excellent |
| 12 mph | 24 meters | 6.8 meters | Good |
| 18 mph | 19 meters | 11.4 meters | Adequate |
| 25 mph | 15 meters | Did not stop | Failed |
Expert Insight: The obstacle avoidance system performs reliably up to approximately 18 mph approach speeds. Beyond this threshold, momentum overcomes the braking capability. For construction inspection work, I recommend capping flight speed at 15 mph near structures to maintain a safety margin.
The system struggled with thin cables and guy-wires under 8mm diameter. Tower crane cables fell into this category, requiring manual avoidance during close approaches.
Subject Tracking for Progress Documentation
ActiveTrack proved invaluable for documenting worker activity and equipment movement. The feature locked onto excavators, concrete trucks, and even individual workers wearing high-visibility vests with remarkable consistency.
Tracking performance degraded when subjects moved behind partial obstructions. A worker walking behind scaffolding would cause the system to pause, then re-acquire once they emerged. This behavior is actually preferable to the alternative—the drone attempting to fly through obstacles to maintain tracking.
Antenna Positioning: The Range Multiplier
Here's where most operators leave performance on the table. The Neo 2 controller uses a dual-antenna system that requires proper orientation relative to the aircraft for optimal signal strength.
The Positioning Protocol
After extensive testing across multiple coastal sites, I developed a reliable positioning method:
Step 1: Extend both antennas to their full 90-degree position from the controller body
Step 2: Point the flat faces of both antennas toward the aircraft—not the edges
Step 3: Maintain this orientation as the drone moves by rotating your body, not just the controller
Step 4: Keep the controller at chest height, avoiding positions where your body blocks the signal path
Pro Tip: The antenna positioning matters most at extended ranges. Within 200 meters, orientation has minimal impact. Beyond 400 meters, proper positioning can mean the difference between a solid connection and video breakup. I tested this repeatedly—same flight path, different antenna positions—and measured consistent 30-40% signal strength improvements with correct orientation.
RF Interference Mitigation
Coastal construction sites often sit near marine radio installations, weather stations, and port communications infrastructure. The Astoria site had a Coast Guard facility within 1.2 kilometers, creating significant 2.4 GHz interference.
Switching the Neo 2 to 5.8 GHz transmission eliminated the interference entirely. The tradeoff is reduced obstacle penetration—5.8 GHz signals struggle more with physical barriers. For open coastal work, this tradeoff favors the higher frequency.
QuickShots and Hyperlapse for Client Deliverables
Construction clients expect polished documentation, not just raw inspection footage. The Neo 2's automated flight modes produce client-ready content with minimal post-processing.
QuickShots That Work on Construction Sites
Not all QuickShots suit construction documentation:
- Dronie: Excellent for establishing shots showing site scale
- Circle: Perfect for documenting vertical construction progress
- Helix: Combines the above with dramatic effect
- Rocket: Limited utility—often clips structures at the top of the move
- Boomerang: Requires too much clear space for typical sites
Hyperlapse for Progress Documentation
Weekly Hyperlapse captures from identical GPS coordinates created compelling progress reels. The Neo 2 stores waypoint data, allowing precise repetition of flight paths across multiple sessions.
I captured 4-second Hyperlapses each Friday afternoon, then compiled them into monthly progress videos. Clients responded enthusiastically—these videos appeared in investor presentations and marketing materials.
D-Log: Capturing Coastal Light
Beach environments present extreme dynamic range challenges. Bright sand and water reflections sit alongside shadowed structure interiors, often in the same frame.
D-Log color profile captures approximately 2 additional stops of dynamic range compared to standard color modes. This preserved detail in both highlights and shadows that would otherwise clip.
The tradeoff is mandatory color grading in post-production. D-Log footage looks flat and desaturated straight from the camera. For inspection work where visual appeal matters less than detail capture, this is acceptable. For client-facing deliverables, budget an additional 15-20 minutes per flight for color correction.
Common Mistakes to Avoid
Flying immediately after ocean spray exposure: Salt crystallizes on sensor lenses within minutes. I learned this the hard way when obstacle avoidance failed after a wave splash reached the landing zone. Always inspect and clean sensors after any salt water exposure.
Ignoring wind gradient near structures: Wind accelerates around building corners and over rooflines. A manageable 18 mph ground-level wind became 30+ mph gusts at the eighth floor. The Neo 2 handled it, but battery consumption increased 40% fighting the turbulence.
Trusting GPS home point near metal structures: Large steel structures can shift GPS readings by several meters. I manually verified home point accuracy before each flight by hovering at 3 meters and confirming position matched visual reference.
Neglecting controller battery in cold conditions: Morning flights in 45°F coastal air drained the controller battery 25% faster than afternoon sessions. Keeping a backup controller battery warm in a jacket pocket prevented mid-flight shutdowns.
Over-relying on automated modes near obstacles: QuickShots and ActiveTrack assume clear airspace. Using these modes near cranes or scaffolding invites collisions. Switch to manual control within 50 meters of any structure.
Frequently Asked Questions
How does salt air affect the Neo 2 over extended deployments?
After three weeks of daily coastal flights, I observed minor corrosion on exposed metal contact points—specifically the battery terminals and gimbal mounting screws. Wiping these surfaces with a lightly oiled cloth after each session prevented progression. The sealed motor design showed no degradation. Internal electronics remained protected by the housing. For deployments exceeding one month, consider a professional cleaning service to address any salt accumulation in ventilation channels.
What wind speed is too much for reliable construction inspection?
The Neo 2 maintains stable hover in sustained winds up to 24 mph based on my testing. Inspection quality degrades above 18 mph due to micro-corrections affecting video smoothness. Gusts exceeding 30 mph triggered automatic landing warnings twice during my deployment. For professional results, I recommend limiting operations to conditions with sustained winds below 20 mph and gusts below 28 mph.
Can the Neo 2 capture useful interior inspection footage on construction sites?
Limited interior capability exists. The obstacle avoidance system requires adequate lighting—below approximately 100 lux, sensors become unreliable. Unfinished construction interiors often fall below this threshold. I successfully captured footage in partially enclosed parking structures and covered walkways where ambient light remained sufficient. Fully enclosed spaces without temporary lighting proved too risky for autonomous flight modes.
Final Assessment
The Neo 2 exceeded expectations for coastal construction documentation. Its obstacle avoidance system handled the chaotic environment of an active construction site with appropriate caution. Battery life averaging 28 minutes in moderate wind conditions provided adequate coverage for systematic site surveys.
The combination of Subject tracking for dynamic documentation and D-Log for challenging lighting conditions produced professional-grade deliverables. Proper antenna positioning—the technique most operators overlook—extended reliable range well beyond typical urban performance.
For construction professionals considering drone integration into their documentation workflow, the Neo 2 represents a capable and relatively accessible entry point. The learning curve is manageable, and the automated features reduce the skill barrier for producing useful footage.
