In May 2019 I posted on here asking if anyone had seen an instructional video for the complete teardown of the Phantom 4 which at the time I had seen not more that 2 or 3 months before than (Early 2019). I believed I had seen it on YouTube, but it could have been on the DJI website...either way, a couple people agreed that they had seen it and it had mysteriously vanished. Others basically said I was mistaken. Well, 5b minutes ago I saw it again on YouTube. It is posted by Timerepairs. In the first 5 seconds it says "Phantom 4 Disassembly Tutiorial Video -- Internal Use", and in the description it says it is meant for repair techs. I agree and I remember that it had very high production value and was done incredibly well as compared to some of the wonderful (ugh) repair videos currently posted on YouTube currently. I know that if I don't like them I should make my own and quit complaining but this is a DJI production...AS IT SHOULD BE. I think its great and I hope it is helpful to all of you who are interested in DYI repair. I do not suggest self repair. I have learned from a lot of failures but experience and a lot of time and money have led to me developing my skills. For me, I don't have the time to send stuff in for repairs although it does take me alot of time for me to do the jobs correctly to my liking and its easy to screw things up badly. You MUST have the proper tools, jeweler's glasses, a ton of patience, and attention to detail. Good luck, have fun.
Anyway, here's the link, great video, no excessive blah, blah, blah or dreary musical selections, .....https://youtu.be/1QdfUzFbO0A
