I don't know if I am in the right place. If not please let me know where to go. I am new to the forum. I have been using my Taranis 16 channel on my quad for a year. I was upgrading to the ardupilot 2.6. I was to the point of calibrating the radio. I had finished doing four channels and when out of the program. When I came back in to cal the fifth channel on the radio was not communicating and nothing worked. I re-down loaded the firmware and it did nothing. Does anyone have a suggestion? Is there a way to take the radio back to a default setting and start over? Any help would be greatly appreciated.
