if your running a small track i would suggest the 2650 on 3s over the 2200 on 4s...
I personally run a 5s 3300 Hyperion G3 VX pack with a Neu 1512 3d 1700kv motor and the runs GREAT not over powered when geared down for a smaller track yet still PLENTY of power when geared up for larger outdoor tracks.

shoot for one of the following
3s-2700
4s-2100
5s-1700
6s-1400

Thanks Rootar. How would the 2650kv run in a truggy though?

On my Hyper 9e I used 17T pinion with the stock 40T spur. I get a little more than 9 minutes of run time. My avg. laptime is around 22-23 second per lap.

2200kv 1/8 mamba monster and 1/8 mamba ESC is incredibly fast in a Losi 8ight-E 2.0 with 4s 30c 5000mah Turnigy, and 15/46 pinion. It is a big step up from the Xcelorin ESC/Motor.

There really is no need to go to a 2650kv.. that would just be stupid fast unless you are on a huge track.

That's just about the same setup as I'm going to run. I'm going for 16t pinion though. I've currently got some 2s 30c 5000mah turnigy's as well. I'll just have to get some 4s ones now.

Ok, my order for a 2200kv has been made! I can't wait to see how she goes.

2200KV 16T for that buggy may be too tall. Have other pinions on hand - try 14T you maybe surprised how well it works for the buggy.

I changed the diff gear ratios on this buggy so that it's the same as the gear ratios on the new Xb808. So when I use a 16t pinion (which is the same as my current clutchbell tooth count) in the speed calculator, it comes out to 43 mph. But thanks for the heads up jmcvicker. I did order a 15t pinion as well.

So which combination is best? If more volts and smaller motor run cooler, why shouldn't everyone be running that combo? If there a difference in the characteristics of running 6S-1400 vs. 3s-2700 other than heat?

I think you mean lower Kv motor correct?

Ideally, the higher the voltage and lower Kv will make electronics run cooler and be more efficient, equaling more runtime.

However, ROAR only sanctions 4S and lower in hardcase format.

it pretty much comes down to what you are used to and what is available to use. 4S lipo with 1900 - 2200Kv motors are pretty common, and give a good balance of runtime with speed. More experienced electric 1/8 racers go with more voltage especially if they need to make longer runtimes.
