Mamba Max Pro infos

[immarcescibile]

I'll use a Mamba Max Pro as official ESC with my brand new 1512 - 1800Kv engine and 4s-40/50c-4000/5000Mah batteries...Should I use a Castle external BEC with 4s configuration according to you guys??
I'll have an Ace1015 steering servo or a Sanwa Erg-WX...
And should I use any external capacitor soldered to the deans (to guarantee protection in intensive usage - considering the 4mmq "little" cables)??

Any particular issues/mods to do to have a reliable Battery/engine/ESC system with my components??

Thanks in advance!
