Are there any non-tamiya battle circuits that can work with standard hobby radios and ant-weight robot ESC's? I've read a bit about Dave's Battle Circuit and the battle circuit from www.tankhobby.com but the DBC is meant for Hen Long boards and I'm not sure about the other circuit. The other option is to give up the money for a Tamiya Sherman, but I don't think I can afford that right now, and probably can't for a long time.
