I downloaded the new software today. My NAZA's are from around June 2012 just before the GPS came out or around the same time. I don't have the GPS for it and just fly it without. I no longer have the older software so I downloaded the latest that was the NAZA Lite. It wouldn't connect, I went to a older version 2.12 and upgraded the firmware and it now connects and calibrates the NAZA but I can"t get the radio calibrate to work??? Any Idea's?
