what kind of truck do you have? Sometimes they just hit the wrong way and snap. I had an rc10gt and broke things all the time. Stadium trucks aren't as strong as buggies or monster trucks. But in my opinion you'll be a better driver if you can controll your st truck, and when it comes time to upgrade to the next level you'll be that much better.
When your just learning your going to break all kinds of parts, and spend some money, but once you get the hang of driving you'll see that parts break less and you'll be having more fun! Take your time and master controlling your ride, It will pay off in the end!!!!!!!!
