Gentlemen I recently purchased a RTR hyper st and really I am just getting used to it as my other nitros were 1/10th scale . I am impressed with everything but ....you guessed it the (legendary or so I read on here) mac 28 . Even with this slug powering it it is quite a bit better than anything I have had as of yet. Just curious though and I know there are a lot of variables if all is equal is a truggy faster than a buggy or vice versa ?
