6S CRT.5 Neu motor question

[Finnster]

The only limitation going HV on a CRT.5 is that the small mah batteries tend to really suffer considering power to weight (mah/g) ratios. The p/w ratio in lipos is not linear, so you end up having to use a much heaver (and bigger/taller dimensions) batt to get the runtime and current capabilities you need. My 4S 2500 batt from Neu seems about as big as I'd want to run. 5S may be doable w/ 2100 cells.
