Hey guys since I am making a trailer for my SCX10 to pull my EXO on I figured I might as well give it dual motors. Now I am not 100% sure on this so be prepared to answer some of my questions. Do I need to get a second ESC if I am doing duals or do I only need 1? Do I need to change my gear ratio? Or can I just keep the stock gear ratio and get a second pinion for the second motor? And when I do this I am going to go with 35t instead of 27t and what motor do you guys recommend? Thanks guys.
