Aussie Open 18 my cleanest run in the finals, nothin special

My last clean final run in the 2018 aussie open, after this race, i checked my quad, and noticed the negative wire had snapped of one esc, taking the solder pad off too, so I rushed to install a spare, i had 2 races before I was on again, took solder iron to the start line, tested direction, all G, took off and the quad was tilting and lacking power, I had replaced it with a faulty esc, not that I would have bumped up again, but it helps to have 100%
