Well, most of the guys here in Cork use Electronize ESC in their models, NO PROBLEM, I have 8 Electronize ESC and I've had trouble with 4, they all still work BUT 4 sometimes work sometimes they don't, I DON'T KNOW ANYTHING ABOUT ELECTRONICS BUT to me they seem to be sticking ( either not working at all or only in one direction ) on calling Electronize on 2 occasions they say its my Battery, BUT 4 are perfect and the other 4 sometimes don't work and sometimes only work in one direction. I have bought a brand new 12v battery, I have swapped radios, changed ESC around in my different models and everything else seems fine BUT the problem remains. Can anybody shed some light. I am using in ALL my models 12v golf trolley batteries, MOCAD golf trolley motors ( so are most of our club - no problems ), does anybody have any suggestions. Thanks Melville
