I have a earthquake 3.0 it seems to be pretty good Ihave wrecked it a couple of times and havent had any problems. Anyways Ijust noticed today that when It is sitting still and Iturn it the wheels bearly move side to side but if Ipick it up and hold it in the air they turn perfectly Ihave changed the batteries and it didnt change anything. Anyways what goin on do u think Ineed a new steering servo? And what servo is good Im not sure cause Ihave never changed one yet. And what else if anything would Ihave to change with it. And Iwould like to get one that fits right in without a bunch of modifacations to the truck itself if its possible. Thanks for the help.
