My Mutank should be here tomorrow. I'm still interested in that TFV4, but I really would want the RBA deck. Where are you all getting your TVF4 from, and the deck, too? I just got my second RX200 in that I bought brand new from the classifieds. Works like a charm. Again, I tried doing an update right away, and it won't work for whatever reason. I've downloaded the updater for Mac, open it, plug in my mod and it shows 1.07 firmware, 1.04 hardware, but updating it, it won't do anything and the firmware number disappears. I guess I'm just going to have to be happy using them as they are.
