I ran my 60a Xerun the other night for the first time, considering I don't have a programmer or turbo ware on it yet, was surprised by how quick it was in general, at least compared to others running non turbo style esc's.
Also I, and others noticed just how good the brakes are, in fact I don't think I have ever seen anything pull up as quick as something with a HW in it, great if your a late braker off a high speed straight.
