Hi everyone! I am new to the 3dr world and only have had my solo for about 2 weeks. I have flown it about ten times with no problems. (No crashes) tonight I went to fly my solo and I kept getting the calibration error: please restart solo. I have restarted to solo and controller over 20 times with no success. I have also done a factory reset with no success. I have also tried to do a level calibration and it errors out on the upside down calibration every time. What should I do? Anyone know how to fix it!?
