I can't fault the new esc i was recommended (quicrun 1060), I've had absolutely no issues with cutting out or loss of power, i got the car out yesterday and as i still have piles of snow here used them as ramps to launch the car, got a few good jumps until the inevitable, too much speed and a bad landing sent it cartwheeling resulting in a snapped top mount on the front and a bent motor plate!! The 3-4 seconds it was airborne it looked epic...
