A drone has four motors and no wings, no rudder, no steering wheel. So how does it go forward, sideways, or turn around? The answer is surprisingly simple: it can only push in one direction, and it moves by tilting that push.
A drone can only push up
The propellers push air down, so the drone is pushed up, along its own "up", straight out of the top of the frame. When the drone is level, all of that push goes upwards and the drone hovers. When it tilts, the push tilts with it: part of it still holds the drone up (lift), and part of it moves the drone in the direction of the tilt.
So every move is really the flight controller changing the speeds of the four motors to tilt the drone, or, for climbing and turning, to change the total push or the twist.
To go anywhere, the drone tilts, and the push goes that way.
Every move is just the flight controller changing the speed of the four motors.
Throttle: up and down
All four motors speed up together: more push, and the drone climbs. Slow them all down and it sinks. Throttle is the only move that doesn't tilt the drone.
Throttle is the only move that doesn't tilt the drone.
Pitch: forward and back
The two back motors speed up and the two front motors slow down. The back rises, the nose dips, the push tips forward, and the drone flies forward. Pull the stick back and it all happens the other way round.
Pull back and it's the other way round.
Roll: sideways
The two left motors speed up and the two right ones slow down. The drone leans to the right and slides to the right.
The middle drawing is the drone seen from behind.
Yaw: turning on the spot
Yaw is the clever one. Remember from the propeller talk that every spinning prop also twists the drone the opposite way. If the flight controller speeds up the two counter-clockwise props and slows down the two clockwise ones, the twists no longer cancel out, and the drone turns right, without tilting at all. Yaw only points the nose. It doesn't move the drone anywhere.

Two sticks
In Mode 2, which most pilots in Estonia use, the left stick does throttle (up and down) and yaw (left and right). The right stick does pitch (up and down) and roll (left and right).
Some beginner drones, like our B200, help you: the throttle stick springs back to the middle and the drone holds its height by itself. On an FPV drone the throttle stays wherever you leave it, and throttle all the way down means falling.
up / down = throttle
left / right = yaw
up / down = pitch
left / right = roll
Flight modes: who levels the drone?
Push the stick and every drone tilts. The difference between flight modes is what happens when you let go.
- Angle mode (self-level): the stick sets the tilt. Let go and the drone levels itself. The tilt is limited, so no flips. Our B200 soccer drones fly like this.
- Horizon mode: like angle mode around the middle of the stick, but push all the way and the drone can flip and roll. Let go and it levels again.
- Acro mode (also called rate mode, or Manual on DJI): the stick sets how fast the drone rotates. Let go and it stays at whatever angle it's at: you have to level it yourself. This is how racing and freestyle pilots fly, like on our whoops and 5″ racers, because it gives full control.
Air mode is not a flight mode. It's an extra, usually used with acro, that keeps the drone under control even at zero throttle, handy in flips and dives.
Air mode and ground effect
Two things every pilot meets sooner or later. Air mode: with the throttle at zero the motors only idle, and normally the drone stops correcting, so in a flip or a dive it tumbles. Air mode keeps the flight controller steering even at zero throttle, so you can flip and dive with the throttle down and stay in control. Racers and freestylers always fly with it on. Ground effect: very close to the floor (about a drone-width), the air you push down can't get away and bounces back up. The drone floats, wobbles and is hard to keep steady. Take off and climb out of it quickly, and land with intent.
Camera angle decides what "level" is
On an FPV drone you see what the camera sees. The picture in the goggles looks level when the camera looks level, not when the drone is level. FPV cameras are tilted up. With a low camera angle, the view looks level when the drone is tilted just a little, so you fly slowly and calmly. With a high camera angle, a level drone only sees the sky; to look ahead you have to lean far forward, and leaning far forward means flying fast. That's why racers use high camera angles, and why the same drone can feel slow or fast depending on how its camera is set.
As a rough guide: 0–20° is for smooth flying and filming (military drones fly here too), about 35° is where freestylers land, 45–65° is racing, and anything above that is crazy, in a good way.
It also changes your sticks. For the same "straight ahead" view, a higher camera angle means the pitch stick sits further forward and you need more throttle to hold your height.
Putting it together
Real flying is always a mix. When you pitch forward, some of the lift goes into speed, so you need a little extra throttle or the drone sinks. A smooth turn is roll and yaw together: you lean into the corner and turn the nose at the same time, like riding a bike. And an orbit, flying in a circle around the ball while looking at it, is roll one way and yaw the other.
And remember: a drone has no accelerator and no brakes. To speed up you tilt forward; to stop you tilt back, and wait for it to slow down.
Start with one stick at a time. Then two moves together. Then three.
Tilt to move. Throttle to stay up.

For trainers: the 10-minute plan
| Time | Slide | Talking points |
|---|---|---|
| 0:00 | Title | Hold up a B200 controller. "Two sticks, four directions each. What does each one actually do to the drone?" |
| 0:30 | Our three drones | Which drones we mean in this guide: the B200 (soccer, throttle springs back, angle mode), the 65 mm whoop and the 5″ racer (FPV, acro, throttle stays put). |
| 1:00 | Fig. 1 | The props can only push along the drone's own "up". To go anywhere, the drone has to tilt, then the push points that way. Every move is the flight controller changing the speed of four motors. |
| 2:30 | Fig. 2 Throttle | All four faster → climbs. All four slower → sinks. The only move that doesn't tilt. |
| 3:30 | Fig. 3 Pitch | Back motors faster, front slower → nose dips → forward. Pull back → backwards. |
| 4:30 | Fig. 4 Roll | Left motors faster → leans right → slides right. |
| 5:30 | Fig. 5 Yaw | Callback to talk 04: each prop twists the drone the other way. Speed up the counter-clockwise pair → turns right. No tilt: yaw only points the nose. |
| 6:30 | Fig. 6 Sticks | Mode 2: left = throttle + yaw, right = pitch + roll. On the B200 the throttle springs back to the middle and the drone holds height; on our whoops and 5″ racers the throttle stays put: throttle down = falling. |
| 7:00 | Fig. 7 Modes | Push the stick and every drone tilts: the difference is what happens when you let go. Angle: levels itself, no flips (B200). Horizon: levels, but full stick flips. Acro: stays at whatever angle. You level it. Air mode = extra that keeps control at zero throttle. |
| 7:40 | Air mode & ground effect | Air mode: control at zero throttle, flips and dives. Ground effect: near the floor the air bounces back; floaty and wobbly. Climb out quickly, land with intent. |
| 8:10 | Fig. 9 Camera | In the goggles, level = where the camera looks. High camera angle: you must lean forward to see ahead → you fly faster. Same view, different sticks: more pitch, more throttle. |
| 8:45 | Fig. 10 | Real flying is combinations. Forward needs a touch of throttle. A smooth turn is roll + yaw together (like a bike). An orbit is roll one way, yaw the other: nose stays on the ball. |
| 9:30 | Takeaway | "Tilt to move. Throttle to stay up." No accelerator, no brakes: tilt forward to speed up, tilt back to stop. Practise one stick, then two, then three. |
Demo / drill: Everyone holds a controller (or imagines one). Call out moves ("forward", "slide left", "turn right", "orbit the ball") and everyone shows the stick movement. Then on the pitch: hover, pitch forward one metre, stop; roll left one metre, stop; yaw 360° on the spot; finally a slow orbit around the ball.
