Buying a used agricultural drone can save you thousands of dollars—if you know what to check.
The biggest risks farmers face are hidden crash damage, worn-out spray systems, uncalibrated sensors, and unknown accident history. That’s why every drone we sell goes through a rigorous, factory-aligned 10-step inspection process before it ships to your farm. No shortcuts, no surprises, just full transparency.
Here’s exactly how we vet every machine:
1. 🔋 Battery Health & Performance Audit
Batteries are the most critical—and most neglected—part of any agricultural drone. A worn battery can lead to mid-flight failures or uneven spraying. We test:
- Cycle count (we reject batteries over 600 cycles for heavy-duty field use)
- Cell voltage balance (max 0.02V difference between cells to prevent power drops)
- Full charge/discharge cycle to verify the advertised flight time
- Physical condition (no swelling, leaks, or corrosion)
2. 📡 Radar & Obstacle Avoidance Calibration
Poorly calibrated radar leads to crashes, missed obstacles, and wasted chemicals. Our process includes:
- Static calibration of all radar sensors against factory specifications
- Dynamic flight testing to verify obstacle detection response
- Cross-check of sensor logs to confirm no past calibration errors
- Functional test of return-to-home (RTH) and low-battery failsafe modes
3. 💧 Spray System & Nozzle Inspection
Worn or clogged nozzles cause uneven coverage, wasted pesticides, and lost time. We inspect:
- Nozzle condition (replace any with visible wear, cracks, or blockages)
- Flow rate calibration to ensure consistent output across all nozzles
- Full system pressure test to check for leaks or pressure drops
- Cleaning and priming of the entire spray system to remove residual chemicals
4. 🛠️ Airframe & Structural Integrity Check
Even small cracks or loose fasteners can lead to catastrophic failure in flight. We perform:
- Full visual inspection for impact damage, cracks, dents, or previous repair work
- Torque test on all frame fasteners and motor mounts
- Inspection of wiring harnesses for fraying, corrosion, or improper splicing
- Water damage check (including humidity test and corrosion analysis)
5. ✈️ Full Functional Flight Test
Every drone undergoes a 30-minute real-world test flight to simulate typical field conditions:
- Hover stability check (no drifting or vibration)
- Full spray system operation during flight to confirm even coverage
- Battery drain rate monitoring to verify flight range
- GPS and compass calibration check for accurate positioning
- Wind resistance test (where possible) to ensure field performance
6. 🧾 Maintenance & Accident History Verification
- Complete service records (if available)
- No history of crashes, water damage, fire damage, or major structural repairs
- Any modifications made to the drone
- Software updates to the latest stable version
7. 🎛️ Controller & Communication System Test
- All controller buttons, joysticks, and switches
- Signal strength and range between drone and controller
- Battery health of the controller and remote ID system
- Pairing and connection stability under different signal conditions
8. 🛡️ Safety & Failsafe System Check
- Return-to-home (RTH) function at low battery and signal loss
- Geofencing and no-fly zone compliance
- Overload and overheat protection systems
- Emergency landing procedures
9. 📦 Pre-Shipping Quality Control
- Re-check all components for defects
- Apply protective packaging to prevent transit damage
- Provide a list of included accessories (extra nozzles, spare parts, tools)
