Mamba Max Pro or Monster for 1512 (1800kv) on 4s

Gday Folks,

Just wondering what the reccomendation for an ESC would be for the 1512 (1800kv) running 4s in a Slash 4x4

If I choose the Pro, I assume I can shorten the ESC wires and add 6.5mm bullets

Will I need to change timing from the default ?

I was thinking of gearing it 21/50 to start with and maybe even 25/50 if temps are ok

Will just be used for bashing

Cheers
