This is sorta brushless related...as I believe my BL power is what caused this.
Somehow I busted a MIP CVD on my FLM Pede:
Notice the nice split in the steel and the lovely curved pin.
I was driving it on flat ground with only a 6 cell pack when this happened. My power is a Feigao 540 8S and Warrior 9920 running on 6- GP3300 matched cells.
