How drones fly - it's all about forces

How and why do drones fly? Drones fly because they fly, right? We have lift and thrust from propellers and magic happens.
It's not magic and everything can be explained using physics:
* thrust is a force
* drag is a force
* Gravity is an acceleration
* force equals mass times acceleration (thank you, Sir Isaac Newton)
* every action causes equal but opposite reaction
Let take a journey into a wonderful world of forces that act on our drones. I will try to keep it short and in layman's terms.
How does yaw work? Drone yaw control - yeah, science! • How yaw works? Drone y... - วิทยาศาสตร์และเทคโนโลยี

Everyday we always learn something from reviewers like you. Thank you so much for this info & your effort. Whn i view your video, You always make it sounds really interesting & that is enough to make most of us to continue flying despite of the many crash n repair efforts in this hobby. Really appreciate it.
Exactly the same content I was searching for😍. Thanks Pawel!
Amazing and simple explanation of the dynamic of drones
Thank you for a very good explanation 😊
Świetny filmik! :)
i like your video, thanks. but in a turn with the horizontal and vertical component the 14N is from 1kg/ 0.7*10N? is that correct?
Hey man, nice video, can you tell me in more detail please how did you use that formula to calculate the 14N force for the thrust? you said (1/0.7)*10 but what formula is that ? and how did you get 10N on the vertical and the horizontal axis, what formula did you use? Thanks.
6:30 500gX5==2kg total thrust-force (TWR==2) will most likely only hover a drone, NOT accelerate it upwards. Thus your assumptions appear incorrect!!! See some online force, and vertical acceleration, calculators under my short videos. Rockets need TWR>4 to lift off; TWR>6 for a safe launch; TWR>10 for a solidly stable launch!!!
It would be really awesome if you could make a video with the same simplicity explaining how to make a dynamic 3D model of hovering drone! Most of the videos out there jump straight to conclusions.
Does any one knows why there is inversion angle in some drone's arm? How to define the angle of inversion for stability of co axial quad-copter?
I was hoping you will explain movement on yaw too :)
well... good idea. One of future vids then
Me too
Do you know any similar content (video would be the best), but in PL language? My 11 years old kid is getting crazy about drones, but his english is not advanced enough to benefit from your, really cool, video.
On 12:02, what is that 0.7? 0.7 radians or something?
Pretty interesting stuff, dude. 😊
It remembered me of school... Good times. 😊
I thrust you. Nice vid!
Hi Pawel. Sorry completely off topic.
I run fixed wing, Taranis 9d plus, Inav 2.1, Matek f405 wing. If a second RTH was setup on channel 15 where the receiver indicator sits with the receiver off would this trigger RTH if the receiver signal was lost (receiver turned off) perhaps coupled with Nav althold. Or am I way off base. (It has been known)
RSSI can not trigger RTH (yet)
Thank you Pawel. I was looking at the no radio signal in the mode setup in the configurator. A loss of radio, set the indicators to 1300. With failsafe set to "no pulses" I think you guys are doing a good job with Inav. Thanks for all your efforts!!@@FPVUniversity
how can we choose a lift coeficient of the drone propler based on its weight
for example a 35 kg drone with a 700mm diametre propler what can be the lift coeficient and how to know it so we can use the right propler for our drone
How can estimate maximum speed of our drone?
Why do all my drones after having them for awhile they can’t get off the ground on a full charge
Interesting stuff,but you lost me right away.I'll try to watch again but don't think i'll catch on .
Trust, thrust. Don't worry I get what you're saying
Not a good video. To someone who never took physics, too many new terms to understand. To anyone who already learned physics, it’s basic things already known. Also, I realized how you round off numbers too happily.
