coming from a 2.1 in your opinion what are the most definitive advantages of the v3? im still using a 2.1 and like it a lot. i dont feel like im bein outrun by ORCA's, Tekins or any other esc's though in the straights or inside. is the additional features really necessary like the 3 point boost expo in the esc? right now i run an orion vst pro 13.5 with it. never gets above 170 degrees in 8 mins (guesstimate) of running. sometimes i dont even bother measuring temp because it doesn't feel unusually flat after a run.
