With these motors it's mostly about hitting a sweet spot by finding the gearing that works for you. It's not as critical as you may think to find the "one" motor that will work. And everybody has their own idea of what "works".

As for the 1515... and 4s/5s... anything in the 2000kv range imo will do very well. Mike ran a 2200kv on 4s his emaxx with slipperential. He geared for about 30mph and had awesome results on the track. So you can't go wrong with that.

I tend to go for the lower kv range and gear up to get the speed I need. This way I have more flexibility to run higher voltage in the future too. (MMM) :)

It's not like you can look at two motors with a 10% or even 20% difference in KV and buy the "right" or "wrong" one. It doesn't matter as much as you imagine. You can work with the gearing to make up the difference between the motors. Of course there are limits....

You don't do that with racing brushed mods... you tend to change winds rather than do much with gearing. And with brushed it's often about getting the right feel or powerband... as much as it is about speed. Brushless hasn't been fine tuned to this degree yet.... it's just about raw horsepower and getting it to work, period. Sorta :)
