Building a drone from scratch is one of the most rewarding projects in the hobby — but between choosing the right motors, wiring an ESC stack, and tuning PID settings, there's a lot to keep track of. This workbook gives you one place to plan every detail, compare every component, and log every flight. What's inside: BUILD PLANNING — Start with a clear project overview: define your drone type, frame size, budget, and goals. Use the requirements checklist to nail down exactly what you need (FPV, GPS, long range, freestyle — or all of the above). Then map out every phase from research to first flight with the build timeline planner. COMPONENT SELECTION — Side-by-side comparison tables for frames, motors, ESCs, flight controllers, batteries, propellers, FPV systems, and radio gear. Each section includes quick-reference tips — which motor sizes match which frames, why your ESC amperage needs 20% headroom, and what to look for in a flight controller processor. Document your final choices in one organized reference. BUDGET TRACKING — A master budget worksheet covering every category from frame to carrying case, plus a running expense log so you know exactly where the money went. PARTS & TOOLS CHECKLISTS — Complete parts checklist (25+ items), tools checklist (20 items including smoke stopper and data-rated USB cable), and a consumables list so you never run out of spare props or zip ties mid-build. ASSEMBLY NOTES — Ten pages of structured build notes with date and phase fields, a wiring diagram sketch area, and a dedicated configuration page for firmware version, receiver protocol, PID values, and rate settings. FLIGHT LOGS — Twenty detailed flight log entries tracking date, location, weather, battery used, flight time, post-flight voltage, and space for notes and issues. Plus a battery cycle tracker for monitoring cell health across up to four packs. MAINTENANCE — Tiered maintenance schedules (after every flight, every 10 flights, every 50 flights/monthly), a repair log, and a parts replacement tracker to stay ahead of wear and failure. PRE-FLIGHT CHECKLISTS — A quick 12-point checklist for every flight, a detailed inspection checklist covering frame, motors, electronics, and battery, and a field kit packing list so you never show up to a session missing your hex drivers. Whether you're building your first 5-inch quad or documenting your tenth custom rig, this workbook keeps your entire project organized from first research to hundredth flight.
