Another route you could go for is MMM esc and a Tekin motor, the 1550 is a truggy motor as is the CC 2200 which is fine unless it dont fit in your car. I want to try a higher cell lower KV set up myself but I already have 2 systems. The 1400KV on 6S 3000-3300mah which would give the same runtime as 1550-1700KV on 4000-4200mah and the same runtime as 1900-2200KV on 4S. Sure the 1900 will give a minute or so more than the 2200. I hear 5S is teh most efficient power usage wise, and anyday 5 and 6S will run much cooler than 4S. In buggy I now that I know more would buy the MMM/esc and Tekin 1900 motor or the new CC 1800 on 4S, or the Tekin 1700 on 5S, or 1400 on 6S. Guys are running the 6S set up in the ve8 and love it, I use the MMM/2200 and like it also.
