My new E-maxx

I am sorry for such newbie questions, but my e-maxx is quite difficult to control steering wise. Very difficult to maintain a straight line. I noticed it pulls to the right upon WOT from a standstill (because of the torque I assume) But when coasting pulls real bad to the left. Adjusting steering trim does not really help. Since I am only used to a xxx-t and evader pro, is this just what happens with a monster truck, or do I need to make some adjustments. It is bone stock, running on street. Thanks again.
