I'm wondering why you guys use the word "copy".
Well, Nosram and LRP sells the same products, just marketed under different brands to cater for the big market.
And it's not a copy of the KO VSF1 competition or Hara Twister V2.1.
Razor = QC3, improved version of Dominator Evo and QC2.
QC3 = WC for 4WD Buggy
Razor = WC for 2WD Buggy
Well, I really love the reactive software.
