I recently got back into building RC's and I scored a Traxas E-Maxx and about a grand in parts for $300. It has two Titan 550 motors in it and has mostly all steel drivelines and shafts. I I bought the conversion plate to convert it to just one motor, but I don't have a clue on what I brushless motor i need to look into. Mainly the Kv part. I don't know which Kv rating that I would need to produce the same or more performance that i currently have and this thing screams. I went and read about the Kv rating and what it means, but that doesn't help me understand what Kv rating would work for me. Like i have seen, 3500Kv, 3800, 400, 5000Kv etc. etc. What Kv rating should I consider? OR,,, should I just stick with the same motors and upgrade the ESC so it will accept an 11.1 battery. I wasn't paying attention when I dropped two 11.1 batteries in it and smoked the steering servo. OOppss! I was looking at a Spektrum
