Just let Phantom hover for a while after you takeoff just to see if everything is good. no erratic behavior, stable gps, drifting etc. I made a rookie mistake when I bought my replacement P3A. Though it was super stable right from the factory. First flight, takeoff from a windy hill, compass error occured right after that and having a hard time bringing it close because gps was disable and flying in Atti.
After a while, try to fly in Atti mode. Will help a lot in an event of GPS related problems.
Total I got 2~3 times IMU, because seen nothing diff
My quad are work well..but I only fly 30m height about 50m away. so far no serious drifting or not hover in place.
GPS work well to. max can get 13 gps at open area.
And I didt upgrade the firmware to avoid common P3s problem.
DO you experience DJI Naza Lite controller?
Because I got a DIY quad but got problem with it.
