I had the P3S for about a week but decided to return it because I was only able to fly it about 1500ft before losing signal and RTH. I was flying at night in a park with open area. Is extremely disappointed as I thought I could go at least half a mile. The reason I bought the standard instead of the adv/pro was the stated 0.6 mile range versus 1.2 miles (not much difference), and the price difference. I'm not even getting 1/3 of the range. Well I recently looked at DJI website and now their advertised maximum range for adv/pro is now 3.1 miles!? How did it change from 1.2 to 3.1. Hardware or software upgrade? Regardless I just ordered a P3A directly from DJI ( you avoid getting older stock with possible shell cracking issue and getting new motor). Also in the hopes that IF there is difference between new production model and old flying range, I will get the 3.1 miles version. I don't think there is a difference because I've seen older (back in May) videos of people going easily over 1.2 miles. I just wonder why DJI had it at 1.2 miles in their old specs. I should get my P3A in few days, will report.
