One idea, many shapes

All drones fly without a pilot on board, but they come in very different shapes. The design decides how long it flies, how much it carries, and what it’s good at.

The four main drone designs, each built for a different mission

​
The main designs

Four rotors. The most common design and the one you’re building.
  • Strengths: Simple, stable, hovers in place, easy to control, cheap
  • Trade-offs: Shorter flight time, limited payload
  • Used for: Learning, photography, racing, inspection, most consumer drones

​
How to pick a design

The right drone depends on the mission. Engineers weigh three questions:

Follow the questions to the right drone for the job

Hover or cruise?

Need to stay still over one spot? Choose rotors. Need to cover distance? Choose wings.

How much to carry?

Heavier cameras and cargo need more or bigger rotors for extra lift.

How long in the air?

Fixed-wing drones fly far longer; multirotors trade endurance for control.

Why a quadcopter for learning?

The quadcopter hits the sweet spot for a classroom: it hovers so you can practice in one spot, it’s stable enough for beginners, it’s small and safe indoors, and its four-motor layout makes the physics of flight easy to see and understand.

Four reasons the quadcopter is the perfect drone to learn on

Watch how your Echo Drone stays level when you let go of the sticks. That “auto-hover” is the flight controller adjusting all four motors many times a second - the single biggest reason quadcopters are easy to fly.
You can name the four main drone types and explain why a quadcopter is the best choice for learning to fly and code.
