1. I have been reading the manual and watching videos, and getting different info on what the lights should do when you get a good calibration. Everything goes good on the horizontal calibrate, but on the vertical calibrate I can only get a flashing green light, no solid green. I'm doing the calibrate in a large open area and have moving 20' and trying again with the same results. The app shows safe to fly GPS, but as I'm flying I often get a flashing Green / Yellow on the rear lights. 2. Does anyone else get a "Weak Signal" flashing intermitently in the status bar. This happens even when I have the carol connected and just a few feet from the controller. Is this a firmware problem?
