You think this 4278 w/ Max 8 Ezrun esc would be good pick for typhon 6s tlr?

[@WTFRCCars]

2250 is high kv for 6s but on 4s like 1:8 race buggies run it would work well

[@nathancunningham8717]

@WTFRCCars you think same esc but with 4268 would be better? Sorry I'm just really starting to wade into motors

[@nathancunningham8717]

Running both 4s & 6s

[@WTFRCCars]

@nathancunningham8717 so for 6s you need a motor to not exceed 50000 rpm, the kv of the motor is how many rpm per volt so 2250kv is 2250rpm per volt, 6s is 25.2v when fully charged so 56700 rpm so long as you don't hold it full throttle for long stints or over gear it you would get away with 6s on the 2250 you just have to be careful how you use it, I run 2250 in my Kraton EXB but geared right to keep the heat down and I don't run wide open throttle all the time :)

@WTFRCCars thanks for the info. That helps me understand what going on with all these numbers. Thanks again, NC
