that's still the original....easily 20+ gallons of fuel and 50+ cycles through my 4S 5000's

the rear carbon skid never wear's as i keep new DE skids on hand when they get thin...the front is the only place i have to watch as once its through the 1st skid its Into the chassis....i actually run 2 skids on the front...you cant really tell but there's 2 on there.
