Nobody on board
A drone is a vehicle with nobody inside. Someone steers it from outside, or it steers itself.
Driver inside
A car. Not a drone.
Steered from outside
An RC car. A drone.
Why “drone”?
A drone is a male bee: it buzzes and doesn’t do much work. In 1935 the British flew a radio-controlled target plane called the Queen Bee. Unmanned planes have been “drones” ever since.

Not only in the air
Drones live in five places. Most have their own short name.
RC boats, robot boats, like Saildrones that measure the sea.
Under water
UUV
ROV: steered on a cable. AUV: swims a mission on its own.
Space
UASV
Satellites, space probes, Mars rovers. Too far to steer live: they mostly fly themselves.

RC car
Nobody inside, someone steers it.
Paper plane
Once it leaves your hand, nobody steers it.
Robot vacuum
Yes, it drives itself. We just don’t call it a drone.
Car with a driver
Someone is on board.
Ingenuity on Mars
72 flights on Mars, 2021–2024. Too far to steer live: it flew itself.

A flying drone in a ball cage.

How it flies
Rotors can hover. Wings fly further. Some drones do both.
Multirotor
Four or more props. Hovers, turns on the spot, flies indoors, but eats battery.
Fixed wing
A small plane. Needs speed, can’t hover. Flies much longer and further.
Helicopter
One big rotor and a tail rotor. Hovers like a quad, more parts.
VTOL
Takes off like a quad, then flies like a plane.

Who’s cooking?
The biggest difference isn’t how a drone looks. It’s how much it does for you.
Frying pan
Manual
You do everything: heat, timing, flipping. You burn a few and you learn.
FPV in acro mode: our 65 mm whoops and 5″ racers. You fly every moment, and you build and fix it yourself.
Toaster
Semi-automatic
You pick the setting, push the lever, it does the rest.
Camera drones and our B200 soccer drones. They hold their height for you. Easy to start. When it breaks, it often goes back to the shop.
Smart oven
Autonomous
You say what you want. It works out how.
Mapping, delivery and patrol drones, the robot vacuum. Someone sets the goal, the drone does the job.

the drone does more
Many drones can switch between modes.

How do you see it?
Not what the drone does. Where your eyes are.
International terms, worth learning: LOS line of sight · VLOS visual line of sight · BVLOS beyond visual line of sight.
pilot
spotter
Line of sight
LOS · VLOS
You look at the drone with your own eyes. The normal rule for hobby flying.
Our B200 soccer drones, camera drones.
FPV
first-person view
You see through the drone’s camera, in goggles. In the EU a spotter next to you must keep eyes on the drone.
Our 65 mm whoops and 5″ racers.
Out of sight
BVLOS
Too far to see at all: flown from a map, or it flies itself. Needs special permission.
Delivery, mapping, long patrols.

What is it for?
The same shape can do very different jobs.
Play
Toys, tiny whoops, first flights.
Pictures
Photos, film, TV, sport broadcasts.
Sport
Racing, freestyle, drone soccer.
Work
Farms, bridges, power lines, maps, deliveries, search and rescue.
Defence
Scouting, protecting, supplying.
A drone is a tool. What it does depends on who uses it, and on the rules.

How heavy?
For flying drones, weight decides the rules. Newer EU drones carry a class label.
0
250 g
900 g
4 kg
25 kg
C0
Most freedom
C1
C2
C3 · C4
Most rules
65 mm whoop · ~25 g
B200 · up to 175 g
5″ racer · ~500 g
folding camera drone · 249 g
Heavier means more rules, more training and more places you can’t fly. The details are in the Safety guide.

Camera or home-built? Different rules
Weight isn’t the whole story. Two things change the rules for small drones too.
It has a camera
A camera (or any sensor that can record people) means you register as an operator, even if the drone is under 250 g. Only toys are let off.
Why: it can see into gardens and windows. In Estonia you register with Transpordiamet.
C1
no class label
You built it yourself
A home-built drone has no class label, so only its weight counts: under 250 g it flies like a C0 (A1); up to 25 kg it flies in A3, far from people.
Under 250 g you may fly FPV in A1, with a spotter (Transpordiamet, 2026). Our whoops: A1, and the camera means you register. Our 5″ racers: ~500 g → A3.

Safety · the law
The rules outside the club
Flying outside our training hall? Drones follow EU rules. In Estonia they are run by Transpordiamet.
Register as an operator
If your drone weighs 250 g or more, or has a camera. Your operator ID goes on the drone.
Pass the online test
The free A1/A3 course and test, about an hour. Needed from 250 g. A good idea for everyone.
Max 120 m high
And keep away from people, roads and buildings.
Check the map
Airports and no-fly zones: utm.eans.ee
FPV? Take a spotter
A spotter stands next to you and watches the drone. Always, even under 250 g.
Rules change. Always check the latest at transpordiamet.ee.

Safety · who is the pilot
Under 16? The coach is the pilot
You have to be 16 to take the A1/A3 test. Younger pilots fly bigger drones only under the direct supervision of a pilot who has it.
coach
16+
A1 / A3
At the club
Outdoor training and official races happen in a designated area, under a coach’s supervision. The coach is the responsible pilot.
Why
Under 16 you can’t get certified yet. Only toys and home-built drones under 250 g have no age limit. Anything bigger needs a certified pilot in charge.
On your own
No certificate? Don’t fly alone. Take a licensed adult with you. They are the responsible pilot. Flying FPV? You still need a spotter.

Remember
A drone is a vehicle with nobody on board.
Five questions tell any two drones apart:
1
Where? Air, ground, water, under water or space.
2
How? Rotors, wings, wheels, tracks or legs.
3
Who’s cooking? Frying pan, toaster or smart oven.
4
How do you see it? Line of sight, FPV or out of sight.
5
How heavy? And: camera? Home-built? That sets the rules.
