It also depends on your track configuration. I race on a small tigh track, only one straightaway worth full throttle. I chose 3s in order to shed some weight. It does get a little hot towards the end of the race but she's ok. And all we run are 10 minute mains.
Now if my track was a little bigger, I would definitely spring for the 4s setup. This setup would be more efficient if geared for the same 42mph(12/48 in my setup). This would still provide great speeds but also longer runtimes.
What packs are you running?
