Fastmounte: Cen has a bad rep:[:'(] Let me tell you, Cen dose not have good custormer service at all. You really want to get them were it hurts, don't buy anything of their's and past it down to other newby's who are thinking of buying Cen product not too buy anything of cen, stay away from cen cars they are junk. Its just a matter of time that cen will fold, because no hobby shops or manufactures even carrie cen products and they said why. A lot of manufactures and hobby shop said we don't carry cen products because alot of custormers don't want to deal with cen because they say that cen sells nothing but junk. If you want a RC monster truck, if ever interested, then stick with Associated, MGT4.6 Losi, Lst xxl Hpiracing, Savage X 4.6 Traxxas, T-Maxx 3.3 or Revo3.3 These company's are the way to go. You will not go wrong and do your self a favor, Get rid of that Cen gst7.7 garbage and save your self a hole lot of pain. Take it from me I have alot of experiance with the CEN gst7.7 and it is rubbish.[:'(] Don't let the guys who have them tell you that they can help you with your truck because you are just going to have this same problem over and over again. Trust Me I know. If this dosn't tell you anything, then stick around rc universe and check Rc monster trucks threads and forums and see how bad they talk badly and I mean badly about Cen gst7.7 people don't like cen at all.
