Any failures with MMM V2 and ext. BEC?

well i have 2 things in mind

the first is i wanted to change the output v on the ccbec and it didnt work , i dont know if i needed a diff program from cc or ? although it was soldered to the esc. the batterys were not hooked up.........


the second thing i was thinking was that i plugged it in and left the esc. switch off , then i went outside , i live in an apartment so the ccbec was on because the batterys were hooked up and it took about 2 min. for me to put the body on and go outside to run.....??

dont know , i just hope that the servo and rx are ok , they seemed to work good the second time i tryed to run until the esc. quit??
