[hailmick]

ive also got an external bec q for mm
im going run my mm with receiver pack on lipos yeah racing 2x 2s x4000mah in series= 14.8v with internal bec wire removed of course
as per rc calcs or brian g site any thing else i should add to it as i dont want it to smoke

but im wondering about lvc for my lipos can i set it as custom voltage ? on mm and will it arm?
its in a pede with 9L feigao power (24/86 pin/ spur)
