HV-Maxx 4.5 or MM and 9xl?

[Serum]

still, the high KV (and the high temperatures) keep me from buying one.

With better cells the 8XL/mm controller combo IS faster, no way around it. again; the power a setup can deliver depends on the quality of the batteries; If the batteries are limiting the setups power both will deliver the same power.

That's my point.

A 4S powered monster can do 50mph, try that with your hvmaxx.
