Flight controls and the three axes — transcript

00:00:00.400 --> 00:00:02.803 Flight controls and the three axes.

00:00:05.400 --> 00:00:09.829 Every movement happens around an axis through the centre of gravity.

00:00:09.829 --> 00:00:13.168 Roll is around the longitudinal axis, nose to tail.

00:00:13.168 --> 00:00:17.469 Pitch is around the lateral axis. Yaw is around the vertical axis.

00:00:19.400 --> 00:00:23.930 Four rotors, two spinning clockwise and two counter-clockwise,

00:00:23.930 --> 00:00:29.755 so their torque cancels. The flight controller changes motor speeds to move you.

00:00:29.755 --> 00:00:32.487 Layouts vary, so check your aircraft.

00:00:32.837 --> 00:00:36.149 Mode 2 is the Australian standard. Left stick up:

00:00:36.149 --> 00:00:41.116 all four motors speed up and the drone climbs. Down: it descends. Centred,

00:00:41.116 --> 00:00:43.103 in GPS mode, it holds height.

00:00:44.837 --> 00:00:50.556 Left stick sideways is yaw. Push right and the nose turns right, without moving.

00:00:50.556 --> 00:00:55.286 The counter-clockwise pair speeds up and the clockwise pair slows.

00:00:55.837 --> 00:01:00.377 Right stick forward is pitch. The rear motors speed up, the front ones slow,

00:01:00.377 --> 00:01:04.562 the nose dips and the drone flies forward. Pull back to fly backwards.

00:01:07.837 --> 00:01:11.308 Right stick sideways is roll. Push right: the left motors speed up,

00:01:11.308 --> 00:01:13.349 the drone tilts right and slides right.

00:01:16.837 --> 00:01:21.435 Quick check. You push the right stick forward. Which motors speed up?

00:01:22.637 --> 00:01:26.216 The rear motors. The nose dips and it flies forward.

00:01:27.337 --> 00:01:33.646 Throttle alone climbs straight up. Add forward pitch and the climb gets shallower.

00:01:33.646 --> 00:01:39.954 Tilting takes some thrust away from lift, so fast forward flight needs more power.

00:01:40.304 --> 00:01:45.279 Real flying blends inputs. To orbit a point with the camera on it,

00:01:45.279 --> 00:01:49.735 hold right roll and add left yaw. Use small, smooth inputs.

00:01:53.304 --> 00:01:58.117 Orientation. With the nose facing away, controls match your view.

00:01:58.117 --> 00:02:03.659 Turn it to face you and they reverse: push right and it moves to your left.

00:02:03.659 --> 00:02:06.940 Lost orientation? Slow down and climb clear.

00:02:07.304 --> 00:02:12.923 Recap: left stick, height and heading. Right stick, direction.

00:02:12.923 --> 00:02:15.063 The motors do the rest.

00:02:15.413 --> 00:02:19.541 Final check. The drone is facing you. You push the right stick left.

00:02:19.541 --> 00:02:20.977 Which way does it move?

00:02:23.613 --> 00:02:26.356 To your right. Facing you, it's reversed.
