re"> i just bought the same buggy and had the same problem with the dogbones (first run out). for the cvd they should already be the steal ones so you shouldnt need to replace them, i would however look and make sure everything is tight because i had to tighten just about everything on mine when i got it, second run out i already cracked both rear wheels! also be aware of the battery slidding around and cracking the on/off switch inside battery/receiver box, hope some of this helps to know what to plan for!......anybody know some good 12mm 4wd buggy wheels???
