No, no, no, don't go 5s. There are a few good reasons why 4s is better in your situation. For one, the amount of power available is way, way to much for any type of track. You don't want something that is comfortable for 50-60 mph when you are spending most of the time going less than 30 mph. With the low throttle that you will be using most of the time, you will be heating up the esc a lot. Even if you geared way down, the motor will be spinning for nothing, and eat up your packs in a hurry. Reason 3 is the fact that 5s is taller than 4s. You want the lowest center of gravity for the best handling.

4s would be better for racing. Just get some good batts, like 30C and 5500mah or more of capacity and you should be good.

i just got done running at a huge track today running 4-5s, 4s on the tekin 2250 truggy motor is about 40 mph with the epa all the way up, speedo 140 motor 140 after 5 min quallifiers, put in a 5s and turned the epa down to 90 from 125 for 5s, after 15 mins, speedo 150, motor 150, i do not believe that turning the epa down affects the temp that much is this agreed by my temps?
