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...

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.

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.

On 12:02, what is that 0.7? 0.7 radians or something?

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?

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

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?

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)

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

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.

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.
