From Zero Knowledge to Building, Tuning, and Flying Your Own Custom Drone.

Tired of piecing together scattered YouTube tutorials, confusing forum posts, and dense academic papers? Drones 101 is the all-in-one, comprehensive textbook the FPV community has been waiting for.

This guide, created by the teams at Genesis Aeronautica and Genesis Development Paraguay E.A.S., is a carefully curated resource designed to take you from an absolute beginner to a confident pilot, builder, and tuner. We've synthesized the best information from across the community into a single, logical, and easy-to-understand book.

And it is completely free, forever.

What You'll Learn Inside

This is more than just a quick-start guide; it's a foundational textbook that covers the why, the what, and the how of FPV drones.

✅ The Principles of Flight: Understand the fundamental aerodynamics and physics that make a quadcopter fly, hover, and maneuver with precision.

✅ A Deep Dive into Every Component: Detailed chapters break down every part of a modern drone, including:

  • Frames: From True-X to Deadcat, understand how geometry defines flight characteristics.
  • Motors: Learn how to read motor specs, calculate thrust requirements, and choose the perfect motor for your build.
  • Propellers: A deep dive into diameter, pitch, blade count, and materials, and how they impact performance.
  • ESCs & Flight Controllers: Understand the "brain" and "nervous system" of your drone, from firmware to communication protocols.

✅ The Complete FPV Video System: A clear, practical comparison of Analog, DJI, Walksnail, and HDZero to help you make the single most important decision for your FPV experience.

✅ The Art and Science of Tuning: A comprehensive guide to PID tuning in Betaflight, enhanced with "Diving Deeper" sections that explain the underlying aerospace engineering principles in accessible terms.

Who This Book Is For

  • The Absolute Beginner: If you don't know where to start, start here.
  • The "Ready-to-Fly" Pilot: If you've only flown pre-built drones from DJI or BetaFPV and want to take the next step into building your own.
  • The Student or Engineer: If you're interested in robotics, control theory, and aerodynamics of multirotors.
  • The Experienced Pilot: If you want a single, consolidated reference manual for all the core concepts of the hobby.

Our Philosophy: Why We Made This Free

This book is not a work of singular invention but one of careful curation and synthesis. It stands on the shoulders of giants and is deeply indebted to the foundational work of community pioneers like Oscar Liang and Joshua Bardwell, the engineering principles in academic texts like the "Small Unmanned Aircraft: Theory and Practice" by Randal W. Beard and Timothy W. McLain, and the collective knowledge of the FPV community.

Our goal was to create a single resource to solve the problem of scattered information. To achieve this, we worked in collaboration with Google's Gemini, using it as a powerful research and synthesis tool to bring this project to life in months, not years. In the open-source spirit of the hobby, we are releasing it for free.
