hello everyone i am just wondering if there is a big gain in handling and performance on a rustler versus a stampede i have a stampede right now and i am going to convert it to a rustler but the only thing i am worried about is the rustler always bottoming out and replacing the plate underneath. The other big this is it's handling. Is it really that improved versus a stampede cause if i run smaller tires on the stampede it seems to be almost the exact height as the rustler but maybe i am wrong i want to eventually get into racing either truck with the bigger benefits but if it's not really going to make a whole lot of difference i am going to cancel my parts on order. Any help would be great right now thanks everyone.
Ps. my test track that i have is a bmx track so if that helps anyone
