I am new to the r/c world and just purchased my first "learner car"!!! I got the everything in a box 1/10 R/C CLK-DTM Team Vodafone AMG-Mercedes. The car is a great lttle car but my question is, is there any way possible to make it a 2 speed car. I thought I was buying one but when I got it out in the parking lot it only has 1 speed. Oh well it was only 85 bucks. And also are there any aftermarket stuff to "boost" it up a little?
