I just picked one up today at local hobby shop and broke it in. idk whats goin on but it seems to be really sluggish when it shifts to second gear. But what scares me is a lot of the time today it would just go full throttle for no reason like someone else was hitting the gas but i know thats not the case. Can anyone help me id hate to see my new baby go wide open into a curb or something cause it did that once today and it proved its strenght but i know its not suppuse to accelerate by itself any help???? Thank you alll
