I marked my 100th flight with my P3P last night. I have had zero problems with this unit other than my own mistakes leading to a shell replacement. But even at that, it flies perfectly. I always take my time pre-flight, get plenty of sats and then hover for a moment before beginning. I have practiced in ATTI mode and tried using the controller with and w/o FPV to simulate signal loss. I have had no battery problems and my horizon is just fine. I really can't find anything to complain about and since there are many threads which share their problems, I thought I would share my success. I think all I need is more batteries and I will be fine. I've had everything from the FC40 up and am extremely pleased with this aircraft. I trust that I have many hundreds more!
