My PV2+ has had stability problems from the get go. I was hoping that the new firmware update might fix things. Absolutely not, if anything it's gotten worse. I've recalibrated the transmitter and controller and this thing loves to dive for no reason. In the begining I thought it might be me as a newby pilot. It's not my piloting but I haven't ruled out that somehow I might have programmed something wrong or I don't understand something about the set up. Most of the abstract crash's occurred when it was between 10 and 20 feet up, 1 was from around 100 feet up. Most crash's had this in common. Crashed after hovering and rotating left. It crashed 3 times today at around 10 feet as I was playing it safe. Sometimes it won't respond to my input to ascend. At one point it was starting to wobble so I flipped it to atti to eliminate GPS interruptions. It was ok for a bit then wouldn't respond to anything so I flipped it to failsafe when it was about 80 feet from where I set the home compass gps setting. It was about 5 feet high and wouldn't go up even in failsafe. It did try to land, it came down once quickly, bounced, went back up to 5 feet and repeated this several time before it lifted up, wobbled and crashed on it's own. It never flew past 5 feet high which is 55 feet less that what it's programed to do in failsafe. It never attempted to return the the compass/GPS home location. Where do I go from here? It makes sounds like it's stoping and going and while it does this it gets some crazy wobbles which usually result in a crash.
