Issues after latest firmware upgrade: X5 camera firmware Gimble doesn't center ( have to correct in settings) also first test fight after upgrade went ok until I tried to land. The landing gear wouldn't go down. I tried to manually bring the gear down-nothing. I also tried to have the sensors bring the gear down- nothing ( I hovered a couple inches from the ground). I had to hand catch the drone, my first time doing that ... hopefully my last. I was able to get the gear to lower after the flight by toggling the H switch 4 times... still don't know if this is going to happen again in flight. anyone else have these issues?
