i've got the mt 2 rtr version, pretty good truck. so i can bet that the ss is even stronger. i have the .18 cv-rx in mine and it flies, doing like 45 ish, my stock tires aren't that grippy any more and are close to being slicks. but it's a good truck. i finally broke something on it two days ago. rear a-arm and that was it, and a rear dog bone flew out some where in the grass. ah well, the truck is great.
