Sorry I was wondering about what the telemetry radio had to do with the crash.
I am using an AR8000 (with sat) and a DX7S
Sorry for the confusion.
Good advice, thanks Richard
When you go to the radio calibration tab in Mission Planner, is everything working correctly? You may have a channel reversed on your RC transmitter.
I had checked the radio but I was going back in to check the calibration again when I discovered that although the board would connect I could not do anything. I will have to wait to get a board that works to find the answer. I am sure I will be back then with more questions.
