Hello, I'm building a new quad and have some problems with my 4 in 1 esc. I wired my esc up to my motors and fc and I got all the motors to spin. But I smelled a bit of a burnt smell after unplugging the battery, coming from the esc. After plugging the battery in for some testing for the motors I saw just a little bit of smoke coming from the battery leads on the esc. Now when I plug in the battery, this happens: VID_20200826_211726.mp4 . Do you guys think I'm able to save it and have an idea what went wrong? I think I just have to buy a new one, but maybe someone has a way to fix it.
