Hi guys, Looking at putting in the Mamba Monster X in my Summit (still doing a lot of motor research) but I am trying to figure out if I need new batteries. Any calculation I have done only seems to give me 2 or 3 minutes... so I am not sure if I am doing this correctly. -Motor would more than likely be the Neu-Castle 2200kV 120A -I have 2x 7600 mAh 2S 25C Traxxas LiPo Series would be 4S 7600mAh (would it become 50C as well?) Parallel would be 2S 15200mAh (does it remain 25C?) I am not to focused on speed, but I do want it to be better than stock. Main focus is certainly crawling and having it perform smoother. Thanks in advance.
