Thats because CEN Monster trucks are nothing more then junk.[:'(] CEN is not going anywere, No time soon. Its just a matter of time were CEN is going to fold, because no-body like CEN products other then the one who are still a brown nose for CEN!!!!!! Those who are still kissing CEN A$%#&%^, are the ones who say that its all right for CEN to still make junk and sell it to the custormers, IN-stead of getting CEN where it hurts the most which is in there pockets. Do your self a favor and stay far away from CEN monster trucks and I mean Far-away. Stick with the ones who are most popular which is HPI savage, Traxxas Revo or T-max, Associated Mgt 4.6, and Losi lst xxl. The companys I just mention are the way to go. You can find parts anywere for them, even at your nearest super market, Look traxxas alone is so popular that they even sell them at pep-boys, check that out!! All rc trucks have some issues at one point to another and they have there issues sometimes because anything thats man made is going to break. But they are not as bad as CEN monster trucks, when it comes to problems CEN Monster trucks takes the cake.
