Ok need some more help....info on kv rating on motor...I'm looking for a 46 size an have found several in that size all are turnigy 46s ...420 kv...550kv...an 670kv...i know there is an rpm difference with the same voltage applied to each motor...so what is the determining factor on each one ....torque...speed...flight time...so does lower kv rating equate to more torque less speed...higher kv more speed more responsive...nust how does that work ....thanks
