VDub,I am so sorry I missed your post!! Not sure how it happened but did! anyway. the specs on the OEM electrics, the ESC is a HobbyWing RTR 80amp 4s max and the motor is again HobbyWing 4Pole P4047 2000Kv Un-sensored Brushless Motor. Being an 80amp RTR esc I recommend limiting your battery choices to 2x 2S 60c discharge, anything more will be too much. However with that battery combination and anything more than 5000mAh capacity, you should see aprox 30mins of runtime and all the power you could ever ask for!! With plenty of traction you could easily do standing back flips and wheelies on demand!! No need for any more power than that!! Hope this helps, but if you have more questions, please feel free to give me a call using the contact info provided below in my signature!
