Well, I'm not really sure, but it is noticeably heavier than my Nitro Revo even with a full tank of fuel. And that is around 10-11 pounds. Yeah, I'm kinda worried about the diffs as well, but is there something better that will fit?? I saw
these a while back and figured they may be a nice combo to use with
this and
this. Add all those prices up and it makes for an expensive set of diffs though!
