You can't really "upload" videos here. You can upload pictures but not videos, they're too big. You need to upload your videos to a YouTube or some other video account and then post it on these pages as a link.
Yeah, I bought a racer and proceeded to screw up the software. Since then I cannot get the quad to see the TX. Gave up on it and put it on the shelf after flying it twice. Got a tiny whoop I been messing with for indoors.
Yeah, I think I saw something on that a while back. If I remember correctly you had a Spektrum radio. I'm using a Taranis so I didn't think I could help you much. Too bad you haven't gotten it sorted, this stuff is a blast but it's a lot of work too. You might want to take a look at the JJPro T1, it's a brushed bird with a full F3 board in it but it's a lot more fun than the Whoop (my opinion, of course) and the batteries last quite a bit longer. It's a fast and powerful little bugger. They should have one compatible with your radio as well. I think I got it for $80.
