Sir, it’s already public, this is a different video stating my drone is very stable, but why does it death wobble suddenly at high altitudes in loiter mode?

I still can’t access your videos and links. Your google drive is not open for me.
Please try this
I never will download 2.58 GB
Sir, there is a view option also use brouser or ardupilot discourse app
No, the stream will be not less. But also as I said I don’t expect any answers from such video.
But you can answer the question asked by Dave. That is probably part of your crash
Sir, I have calibrated the motor multiple times which also includes pwm range, but the motor starts rotating at 10% throttle when I set spin armed to 0.2. what do you recommend what I should do? Also please check if all values are correct what should be the ideal spin minimum and spin when armed?
All post this again and then I’m done attempting to help you. Setting Motor Ranges.
Sir, my drone was flying well and suddenly magic smoke appeared, and only the ground wire of pmu burnt other than that everything is unburnt, what might be the issue and what should I do. I also notices voltage go down during flight on battery monitor. Please do reply. @amilcarlucas , @Allister , @dkemxr , @Joshua_Kordani .
One of the GND main power cables got disconnected, and the entire power is now flowing over that tiny GND wire.
Fix your main power connections.

Such a picture shows a massive over current for the small wire. This current heats the wire and the isolation burnt. The reason for the over current I cannot say as you don’t show any details like a log.bin file.
One reason could be a general wrong installation, to much power connected to the small wire. But I don’t think so as you work now sometime with the system.
Next reason can be a defect on one of the connected modules which causes higher current as normal. This could be a blocked servomotor or a defective controller or …
And a reson could be a loose or brocken GND connection on the main power line and therefor the GND current is going a different route.
Post a link to the last flight log.
Sir, thank u soo much for this tip, this was the problem indeed, also about mounting components especially escs I had following questions:-
-
the 3 esc wires has ac current so it might generate magnetic field that inturn induces current in its surrounding components ( noise) so how far should we mount it away from flight controller?
-
does dc side of esc produce any noise in flight controller?
-
does ac side of one esc[1] is close to the other esc[2] itself will that cause issue in microcontroller of the other esc[2] i.e noise/interference?
-
if we pass all 12 motor wires through same hole will that cause interference in each other’s voltages?
-
sir are the mountings in the picture below is efficient? i.e out of 10 score, how will you rate it regarding the components causing noise with each other.
Thank you!
Sir, the .bin file was for reason not generated 
because sd card was not on the flight controller.
Yes sir, I indeed found the problem. It was loose ground wire
Why not? Never fly without the opportunity to review a log.
The soldering on that PCB is totally unacceptable.

Yes sir , I will keep that in mind, now onwards. Sir the pcb is reused so this left its mark on it, I will try to replace it if possible. The esc motor wire are 6.5 cm apart from flight controller, they are situated just below of flight controller, so is it okay?
Disable the Flight Controllers internal compass.

sir, do i need to use notch filter in the below case? for some frequencies the amplitude is greater than -50 db (just a little) , else everything is below -50db. https://drive.google.com/file/d/1EK9zZ2Jsr7vIr4m4TWd5DxCwQBHtWwQh/view?usp=sharing @amilcarlucas @dkemxr @Joshua_Kordani @Allister
