05 · How a drone moves · fig. 1
A drone can only push up
Thrust
Level: all the push goes up (hover)
Thrust
Lift
Move
Tilted: part of the push moves the drone
The props only push along the drone's own "up".
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

Seen from above · front ↑ · + faster · − slower
Left stick ↑
All four motors speed up together → more push → the drone climbs. Slow them all down → it sinks.
Throttle is the only move that doesn't tilt the drone.

Right stick ↑
The back motors speed up, the front ones slow down → the nose dips → the push tips forward → the drone flies forward.
Pull back and it's the other way round.

Remember: every prop twists the drone the other way. Speed up the counter-clockwise pair and slow the clockwise pair → the drone turns right, without tilting.
Yaw only points the nose. It doesn't move the drone anywhere.

Two sticks · Mode 2
THROTTLE
YAW
PITCH
ROLL
Left stick up / down = throttle left / right = yaw
Right stick up / down = pitch left / right = roll
Most pilots fly Mode 2. On some drones, like our B200, the throttle springs back to the middle and the drone holds its height. On our whoops and 5″ racers the throttle stays where you leave it, and throttle down means falling.

Flight modes: who levels the drone?
Push the stick and every drone tilts. The difference is what happens when you let go.
levels itself
stick pushed
Angle · self-level
The stick sets the tilt. Let go and the drone levels itself. Tilt is limited: no flips. Our B200 soccer drones fly like this.
levels itself
stick pushed
Horizon · level + flips
Like angle near the middle of the stick, but push all the way and it can flip and roll. Let go and it levels again.
stays tilted
stick pushed
Acro · rate · manual
The stick sets how fast it rotates. Let go and it stays at whatever angle it’s at: you level it yourself. Racing pilots fly acro, like on our whoops and 5″ racers.
Air mode isn’t a flight mode. It’s an extra that keeps the drone under control even at zero throttle, used with acro. DJI calls acro Manual (M).

Air mode and ground effect
throttle at zero
Air mode
With the throttle at zero the motors idle, and normally the drone stops correcting. Air mode keeps it steering anyway, so you can flip and dive with the throttle down and stay in control. Racers and freestylers always fly with it on.
wobbly, floaty
about a drone-width
Ground effect
Close to the floor the air you push down can’t get away: it 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
In the goggles you see what the camera sees. The picture looks level when the camera looks level, not when the drone is level.
15°
camera tilt
Low angle, tilted a little
The view looks level at a gentle tilt: slow and calm. Good for learning, smooth filming and small indoor tracks.
55°
camera tilt
High angle, drone level
Hovering level, you only see sky. To look ahead you have to lean forward…
55°
camera tilt
High angle, leaning forward
…and leaning that far means you’re flying fast. That’s why racers use high angles.
Rough guide: 0–20° smooth flying and filming (military drones too) · about 35° where freestylers land · 45–65° racing · more than that: crazy, in a good way.
Same view in the goggles, different sticks: with a higher camera angle the pitch stick sits further forward and you need more throttle to hold height.

Putting it together
sinks…
Forward = pitch forward + throttle
Tilting turns some lift into speed. Without extra throttle the drone sinks.
Smooth turn = roll + yaw
Lean into the turn and turn the nose at the same time, like a bike in a corner.
Orbit = roll + opposite yaw
Slide sideways while turning the other way: the nose stays on the ball.

Safety · checklists
Before, during, after
1
Before
Frame, motors and props: no cracks
Props tight and on the right motors
Battery charged, not puffy
Channel booked, 25 mW
Safe spot, no people in the way
Tell everyone: “Plugging in!”
2
During
Keep it where you or your spotter can see it
Stay away from people and animals
Watch the battery: land in time
Something wrong? Land, then fix
Say it out loud: taking off, landing, crash
3
After
Disarm, then battery out
Check props and frame
Let the battery cool before charging
Not flying for days? Storage charge (3.8 V)
Clean up your spot
What went well? What next time?

Remember
Tilt to move. Throttle to stay up.
A drone has no accelerator and no brakes. Practise one stick at a time, then two moves together, then three.
1
Throttle is the only move that doesn’t tilt the drone.
2
Pitch and roll tilt it. Yaw only turns the nose.
3
No brakes: to stop, tilt back, and wait.
4
Angle mode levels itself when you let go. Acro doesn’t.
5
Higher camera angle = more forward stick, more throttle.
