Would anybody be able to help me with Mission Planner comms to APM2 board? I've hit a hump that is troubling me. I'm not able to get past radio calibration step on new board and gear (Turnigy 9ch). I've got considerable IT experience and some APM1 successes but this prob is a B. Could just be a faulty dataflash card or PC security jamming actions, Be great to hear your thoughts 9453 3580 problem…
