ST-R Brushless Help!!!????

[str8up]

Cool thanks guys. Everyone has helped out alot. I currently have the 5000 in 3 cell and ran it with my evader with the mamba 5700 and it lastested forever and ran reall really good.
SO MY LIST IS -
currently own -
MM esc
Fans
Rx batt and Nomadio with telemetry
buying later tonight if no objections from fellow rc'ers
Feigao 540c (has the heat sink already) 8xl
5mm bore 13 - 18 pinions
max amps 5000hv 4s lipo

I am going to disable my internal bec and i believe i do this by disconnecting the red center wire from plug on the esc and set the cutoff in the settings to no cutoff. please correct me if i am wrong but from everything i have seen and read that is the way to do. Again thank you all for the help.
