Somewhere along the way in troubleshooting my new Z3D problems and redoing all the latest updates my motors won't start. I have followed pointers on this forum and Google and have been trying for 2 days now to get the advance IMU calibration to work correctly. The mod numbers are in the under 1000 range. Mostly around 350. I've tried waving a magnet around the magnetic compass more then a dozen times but I still can't get the number in the 1400 to 1800 range that I read it was suppose to be in. I did fly the Phantom after installing the new Z3D (broke my Z2D in a crash) but it had some yay & pitch twitching that I was trying to fix when the motors quit working. Also I swear I thought my RC power light use to be red and now it's yellow. I can get through the GPS calibration after powering on OK. If anyone has any suggestion for me to try, I would greatly appreciate it.
