RE: SCX10 NEED HELP! I'M NEW TO RC.
Adding a 2nd motor isn't gonna help you much. Start here- upgrade your trans with steel gears.All of them. Then getyourself a good 17-20t brushless setup. Run a 20-24t pinion, &n you should have what your looking for. Works everytime. 2 motors doubles your power, but wont change speed at all if you don't change gearing. Before you gut the thing, pop a 24t pinion on your 27t motor, & see wutcha think.
