Simple. The OP has acquired a stock of high-value drones and wants to donate them to the Ukraine war effort.

I'm so pleased for you, and hope you will not give up. My first aeroplane flight (rubber power, not radio-controlled) was also straight into a tree. I persevered with self instruction and ended up writing an article "The foolish pilot" which was actually accepted for publication by a model...

Trying to be positive. Is it stuck on a branch which can be shaken to get the drone to fall out? If so then the plan is to attach a thin string to a stone or ball and throw the ball so that the string passes over the branch. Attached to the other end of the string is a much thicker cord, which...

Fair enough. Putting the phone into flight mode will disable incoming calls and texts anyway

I bought a drone and controller with built in screen on the basis that I wanted to keep the two functionalities separate, as in I don't have to dismantle anything in order to receive a phone call

It's to explain that the transmitter must match the receiver inside the drone. If you collect drones of different kinds you may end up collecting transmitters as well

For protocol read language. In the good old days you couls buy any old transmitter and any old receiver, put a pair of matching crystals in them and the one would control the other, with minor differences as to which channel was which. With the move to the 2.4GHz band this is no longer the case...

Did you know that drone pilots in Tennessee must abide by federal regulations? Those regulations specify, amongst other things, a maximum height of 400 ft above ground level, and also that the drone must remain in line of sight.

Using a drone as a stereoscopic camera is a fun idea, but there are limitations, the main one being that as the pair of pictures is not taken simultaneously there cannot be anythig moving in the subject area. I presume that the 90° rotation in instruction 1 is to define the start of a 180°...

I repeat: "if one specifies that in a 4 motor drone two are sufficient to keep it aloft". Yes, this is more power than most drones have, but it is an engineering possibility. If one motor fails two can continue to keep it aloft while the 3rd motor can then function as an attitude controller. It...

That's not entirely fair. bearing in mind that single engine failure is less serious in 4-engined aeroplanes than in 2-engined aeroplanes, and in turn single failure is less serious in 2-engined than in in single-engined. If one specifies that in a 4 motor drone two are sufficient to keep it...

Yes, it's getting power but not nearly enough. The lights come on only briefly, and disappear as the load requirement exceeds the available current supply. When you connect the phone the current drawn from your phone is sufficient for the indicator lights but still not enough for the display.

There's something seriously wrong with the battery or with the connection between battery and controller electronics. Bought new? Send it back. Bought second-hand from a dealer? Send it back

Charge the battery?

"Please explain to the audience how WiFi is used to transmit video from a drone that is flying several thousand feet from the controller" Certainly. Transmission of data wirelessly requires a matched pair of transmitter and receiver. The matching involves first an agreement on the nature and...
