Using AA batteries to power the FR2 doesn't cut it for me anymore. For some time now I've been looking for a solution using a RC battery pack with a tamiya connection and make a tamiya to DC cable. Quite a simple procedure, however I just can't seem to find the model of the DC connector that fits into the FR-2. I've tried all the different DC plugs I have around the house, nothing fits. I've been searching the internet for the correct model to the point of pulling my hair out, still no luck. I don't have the FR2 AC mains adapter otherwise I would cut the connector from that. Can anyone help me identify the DC connector?
