Brushless or Nitro??? They are both fun..the twister will come with 2.4 ghz radio and shockwave will have am. The twister will be faster. The shockwave will have aluminum chassis. Shockwave will be all wheel drive twister 2wd. Both are sweet, but for this choice I would go twister. This answers what you asked....now I will throw in tornado only because it is the same chassis as shockwave but with 2 speed tranny and .18 motor. Couple other mods but now I would pick tornado its only about $40 more and well worth the $$$. Good luck!
