using a similar 4s setup you would buy a motor that is comparable to say a nitro cars RPM's

Using a 6s setup you would (assuming you want to "compete with Nitros") get a motor similar to RPM in nitro cars

The only difference is amperage difference and hence the price difference on speed controls... More voltage = less amps pulled ^_^

Both Setups are competative... a 6s setup would run a bit cooler but cost a bit more for the speed control

Don't forget about the batteries.. if you need say 2kw peak, then at 6s you will be drawing 90A and 4s 135A. So you need much bigger or higher quality batteries to get that peak. Then also there is run time issues, if you run 4s you will need bigger packs again to get the same runtime as the 6s.

I hope he bought batteries better than say 15c ^_^

on that type car ide go Neu 30c Batteries

Yeah I'm using 3 X NEU 2s 25C 5000Mah packs. I brought THESE because I also use them in my 1/10 touring car.
I'm looking at down sizing the Mah to reduce the overall weight of the setup. I think I would be able to get away with something 6s and around 2500 Mah in 30C of course. Down side will be the reduced runtime upside is the car will be around 400g lighter.
