I did watch your videos, I have no interest in them because it's all stuff that has been covered in huge detail countless times over the last four years, but I thought I should see how you did them.
Just a few bits of feedback. Talk louder and clearer, there are several points where your voice is so quiet you can hardly be heard. Secondly, stay slightly further away from the camera so that people can see more of you and the kit, rather than cutting off half of the item as you often do in your rotor disassembly video, then if you need to show something in more detail move it in closer to the camera rather than having it in close all the time. Thirdly, blow your damn nose before you record a video, nobody wants to hear you sniffing constantly throughout it, if you have to then edit out any undesired audio before you upload the video.
Just a few things that occurred to me while watching. However, as others said, you need to do something more original, this kind of thing has been done countless times before and so you don't stand out at all.
