I eventually crashed into a tree very lightly, everything fine,thank goodness.i packed up quick lol. took the ps3 out today for a second flight. everything fine safe to fly, 12 satelites available.hovered for 30 seconds all good.oh I took it out of beginners mode as well with rth height set at 50 mtrs..took it up and away . about 40 mtrs away no gps again . a slight wind as well.the ps3 drifted again. my heart went. rth again.. did the compass calibration again. exactly the same happened.my confidence is knocked now. can anybody help please?
