rcboyz has awesome shipping and customer service. you gott realize if you take two 2.5 traxxas motors they are both .15's if you take one os .30 you have the same displacement. ok now you got one motor on the spurr gear and one motor to tune you will have more power. the reason people put 2 or 3 motors on a truck is the presige of saying they do. still waiting for v-2 power
