My least favorite connector... the Tamiya plug. I personally hate the plug, it does easily fail after just a few mating cycles I've found. I highly suggest using Deans connectors or even XT60 plugs instead of the stock ones but only out of preference, not necessity. The mating cycle rating for those plugs is much higher. I always seem to break the Tamiya plugs myself too, I even make Deans plug power cables here for people. Send me and email and reference this this ok? I might have a simple solution for you
