WHAT TO SCAVENGE / PRIORITIZE

Focus on high-value electrical components:

Power

• microcontrollers
• wiring & connectors

Sensors
• cameras
• GPS modules
• phones (great sensor packages)

Communication
• radios
• antennas
• routers

BIGGEST LIMITATIONS

Even advanced drone programs are limited by:

1️⃣ Energy

Battery tech = flight time ceiling

2️⃣ Communication

Signal range & interference

3️⃣ Maintenance

Motors, props, electronics wear out

4️⃣ Weather

Wind, rain, cold

Drone Building 🛠️

Core Components (What Everything Does)

1. Flight Controller (Brain)
• Microcomputer that stabilizes the drone
• Reads sensors and adjusts motors in real time

2. ESC (Electronic Speed Controller)
• Converts battery power into motor control
• One ESC per motor

3. Motors (Brushless)
• Spin propellers
• Provide lift and movement

4. Propellers
• Create thrust
• Different rotations (clockwise / counterclockwise)

5. Battery (LiPo / Li-ion)
• Main energy source
• Determines flight time

6. Frame
• Structural support
• Holds everything together

What You Need (Core Parts)

Electronics
• Flight controller (compatible with PX4 Autopilot or ArduPilot)
• 4× ESCs
• 4× brushless motors
• Radio receiver + transmitter
• Power distribution board

⸻

Power
• LiPo battery (3S–6S typical)
• Battery connector (XT60 common)

⸻

Structure
• Quadcopter frame
• Propellers (matched to motors)

⸻

Optional (but important)
• GPS module
• camera (FPV or mapping)
• telemetry radio

1️⃣ Frame Assembly
• Build or assemble frame
• Ensure rigid structure
• Mount points for motors and electronics

⸻

2️⃣ Motor Installation
• Mount 4 motors to arms
• Ensure correct orientation
• Pair with correct propeller direction

⸻

3️⃣ ESC Integration
• Each motor connects to one ESC
• ESCs connect to power system
• ESC signal wires go to flight controller

⸻

4️⃣ Flight Controller Setup
• Mounted centrally (important for balance)
• Connected to:
• ESC signals
• receiver
• power

⸻

5️⃣ Power System
• Battery connects to distribution board
• Power distributed to ESCs
• Voltage regulated for electronics

⸻

6️⃣ Radio System
• Receiver connected to flight controller
• Transmitter sends control inputs

⸻

7️⃣ Calibration & Configuration

Using:
• PX4 Autopilot
• ArduPilot

You configure:
• sensor calibration
• motor directions
• control mapping
• failsafes

Motor Direction

Quadcopters rely on opposing spin:
• 2 motors clockwise
• 2 motors counterclockwise

This cancels torque and stabilizes the drone.

⸻

⚖️ Center of Gravity

Everything must be balanced:
• battery placement matters most
• uneven weight = unstable flight

⸻

🔋 Power Matching

Motors, ESCs, and battery must match:
• voltage compatibility
• current limits

Mismatch = failure or damage.

⸻

🌡️ Heat Management

ESCs and motors generate heat:
• airflow is important
• overheating = shutdown or damage

⸻

🚫 What NOT to Do (Important)
• Don’t oversize propellers beyond motor spec
• Don’t mix incompatible battery voltages
• Don’t skip calibration
• Don’t run without failsafes

DRONE FLEET SYSTEM (SETTLEMENT SCALE)

This can be very useful after SHTF and your group requires drones

A functional drone system has 4 core pillars:

1️⃣ Charging & Power
2️⃣ Rotation & Deployment
3️⃣ Maintenance & Repair
4️⃣ Command & Control

If one fails → the entire system degrades.

⸻

⚡ 1️⃣ CHARGING SYSTEM (Energy Backbone)

🔋 Charging Types

Central Charging Station
• main hub
• multiple chargers running in parallel
• powered by:
• solar array
• generator
• battery bank

⸻

Battery Swap System (Most Efficient)

Instead of charging drones:
• remove battery
• insert charged one
• redeploy immediately

This is how real fleets maintain uptime.
🔧 What You Need
• multi-port chargers
• battery storage racks
• voltage testers
• fire-safe storage (critical for LiPo)

⸻

⚠️ Critical Risks
• battery fires
• overcharging
• degraded cells

Battery management = highest priority safety issue

2️⃣ ROTATION SYSTEM (Keeping Drones in the Air)

🎯 Goal

Maintain continuous coverage with limited drones.

⸻

Example: 6-Drone Rotation

Drone
Status

1
Active

2
Active

3
Ready

4
Charging

5
Maintenance

6
backup (charged)

⏱️ Rotation Cycle
• flight time: 20–40 min
• swap interval: stagger launches
• always have:
• active drones
• ready drones
• charging drones

⸻

🧠 Key Concept

Never let all drones be in the same state.

Stagger everything.
If you have 4 charging, and one in maintenance, your system failed.

3️⃣ MAINTENANCE SYSTEM (What Keeps It Alive)

🔧 Maintenance Levels

⸻

Level 1 — Quick Turnaround
• propeller replacement
• battery swap
• visual inspection

⏱️ Time: 2–5 minutes

⸻

Level 2 — Field Repair
• motor replacement
• ESC replacement
• wiring fixes

⏱️ Time: 15–60 minutes

⸻

Level 3 — Deep Repair
• flight controller issues
• sensor calibration
• frame rebuild

⏱️ Time: hours
