8ight-t 1.0 Race Roller Conversion Help

See the problem here is i know nothing about the KV rating on motors. I was under the impression that the 2200kv motor that came with my combo would be all i ever needed, but now i see guys with 1650kv motor and am wondering wtf? I just need a crash course in brushless is all i guess. so what do i need to know?

2200kv is good for lower volt operation, while lower kv is good for HV. Shoot for about 35000rpm. You get rpm like this: rpm=kv*battery voltage (not amt. of cells) each cell is 3.7v, so for a 4s pack the voltage would be 14.8v and for a 5s it would be 18.5v. Got it?

so shoot for 35k rpm i got that and seems easy. so can i use any brushless KV motor with my setup?

For 4s-5s 2300-2000kv...
