Well I took out the Castle 4600 and ended up going with the Traxxas brushed motor. It feels great to me as now I have the perfect amout of speed for some fun, and climbing longer hills with some wheel spin but plenty enough power and control for the lower speed stuff. I turned the EPA down to 85% and its just where I want it. Not enough to really tear it up but enough to have maximum fun. Now its just charge batteries and run. After I put the new motor it I ran another 45 minutes and me and my buddy Tim had a blast.
