just updated to new 3.16 , had problems would not connect and would not update, i had to reinstall windows 8 drivers, then the new update downloaded and installed with no problem. it will reset all your parameters back to basic, you will have to reset every thing, and recalibrate everything, including the compass, after that its a breeze, will test fly tomorrow and give everyone a heads up on how it flys. note it will say gps error 27 till you recalibrate the compass. :geek:
