A mad brushless setup help

[Hayden]

wow so much to think about I’m still studying these setups. so is it that sensored motors have smooth acceleration?. I was looking at the Lehner website and my eyes where drifting towards the bigger motors like Basic XL 5000 and bigger, will it work if I go huge to get maximum speed and control? I can use 2 3 cell packs or what ever to get it to run.
what about a phasor 15-3 (I can ge it cheap)its not meant for it but it can be modified.
