sintered what?

[_paralyzed_]

i bought it as a system, ran two charges and snapped a rotor, got it back ran 1/2 a charge in a rustler and got it wet, got a faulty replacement sent to me for a 1/4 charge, as it sits right now i've got over $400 into a novak setup with less than 4 charges through it, right now i'm waiting for an inverted motor mount from kershaw designs because i put the diffs in backwards and don't want to tear down my truck
