HPI Savage RC- Go to the Trx forums or Rccna and Mike (worlds fastest nitro revo owner) also known as Over_Revo and he will clue you in on everything you wanna know I'm sure. Also its real mature to start calling others "most stubborn and clueless " when your one of those individuals yourself. And I believe Mike lives in Canada, you may just get a chance to see the worlds fastest revo...if your not afraid that your intelligent savage will be dumbed down when the revo blows by it
Also your thinking of CB and Spur combo's...your forgetting the revo has multiple gearing ratios, we can add RCM diff kits and install buggy or truggy diffs, we can change the spur and cb, we can also change the tranny gearing with wide,standard, or close tranny sets and thanks to the slayer we can run higher gearing and get more top end out of the truck since the slayer gearing is higher then your standard revo 3.3 since the slayer has to compensate for the 2.2 tires.
