you must be the dumbest person I've ever seen on this forum. If you knew anything about rc you would know that the mip and traxxas replacement drive lines are shit and bend all the time. I know this from experience with them. The stock ones never bend. I will give it to you this, FLM make quality CVDs but that is just about the only company i know of that makes solid CVD's. Ask anybody who has had a bl revo, stampede, vxl rusty, vxl slash, etc.... The stock drive lines hold up very nicely. So keep your dumb ass comments to yourself.
