After pluging in the battery, the VU flashes orange and then red, or orange then three red flashes. It does this in all three modes. I would expect that the orange would change to green in GPS mode and stay red in Manual mode, but it does not change. I do not believe it is getting a sattelite lock, when I put it in GPS mode it is all over the sky. Also when switching from atti to GPS the MR drops, and I need to give it additional throttle to hover.
I cannot calibrate the compass. I get it into calibration mode just fine, do the calibration dance and then get flashing red at the end indicating it did not take. I checked the IMU calibration and it is good.
I have adjusted for magnetic declination. All settings in the assistant look good, and all switches are doing what they are supposed to do.
It had a very hard landing, landed right side up. I rebuilt it and took it down to the local park and flew the crap out of it. GPS held. Since then I have had neck surgery and the quad has been shelved for last two months.
I was flying in my yard to day when all of the above conditions exhibited themselves. We now have a roof full of solar panels, wondering if that could be causing the problem or is my Naza or GPS toast?
