I recently had to get a new aircraft after suffering a fatal crash from 400'. I got just the craft since I had the rest of the pieces. I connected to Naza and did the advance calibration but 2 things I noticed. One was the page that showed the controller signals showed no movement when I moved the sticks and second was on the bottom of the window it showed mode as fail safe. When I tried compass calibration all I got was flashing yellow led indicating transmitter not connected. Sorry to be long winded but I wanted to try to cover everything to limit the extra questions trying to troubleshoot it.
