In this video, I was testing my new settings on my xerun V3.1 esc. On my first speedtest I had it on practise mode, this time i'm using 2s battery's, I putted it on sport mode "dang it ran like a 3s at my previous settings :S"!!! This insane speed increase made me overexcited which had as result I got my car broken within 15 minutes. Because of a bumpy road my rear suspension broke off, also some of the bolts got bended. The car ran like a beast insane speed, just allot of fun ! :D
