Has anyone had this problem? After my Phantom 3 warms up and states it's safe to fly, every time i'm about to take off i receive an error, believe it's error 42, after i attempt to active my auto take-off. If i calibrate my IMU under sensors, everything is fine and i take off. Something else i notice is i'm receiving low signal strength error initially before i take off but once i'm going it seems to fly ok, although i believe my range is much less than what other people are reporting. I can never make it to 200 meters before i start losing my signal, picture starts to break up and weak signal errors. Any help would be appreciated.
