I'm going to recalibrate all the ESC. Realized that I'm dumb and I don't have to do any desoldering to do it

So once that is done and I have a new prop spinner, my next test will be to really make sure they are all on tight and then try again.
Ok here's one question about the motors and the props... what order do things go onto the shaft? There is a little (mostly) flat disc, the prop and then the spinner. From bottom to top is it disc, prop, spinner? Or does that disc go on top of the prop?
