well with my first MMM the fan died and I didnt have another on hand so I hooked up my second one and after 10 mins of running today it diedit looks to be a failed BEC you can turn the switch on and off and the fan jogs back and forth ever so slightly. Looks like I will need to send the dead one back to CC and while I am at it might as well the other one too......I have a pistix adapter so maybe in the meantime I might go with the HV110 ESC and also thinking about the MGM 9032. When I send the controller back to CC do I need to have the receipt?
