I got my first P1 in April of 2014. Bought 2 more in 2015. When I was first flying my first one, I had a couple boo boos. My fault and no damage. All still flying well. Now, I have to assume the later birds should be better but more complicated as features were added. But along with these features increases the chance of someone making a mistake and trashing their bird. I know the P2 had some issues with some ESCs. P3s had some cracking on the shells...but that wouldn't cause a crash or fly away. I don't remember hearing all of these problems with the P1 models. Mine never have a problem and all are stock...no windsurfers, no amps, only 9450 props on one because it's carrying a metal gimbal, gopro, and larger battery. I follow the forum and read about all the problems people have and can only assume that most of the problems are pilot error in some way. Not totally understanding the features or not implementing them properly to get expected results. With the ability to fly further and viewing a screen adds more risk of things going bad...like the monitor crashing, some problems with software glitches, smart batteries with more connectors to keep clean. I know it's really cool to fly your bird out miles but I think if people didn't push the envelope so much and practiced VLOS more, there would be less loss of our toys. I'm not saying against people that like long range flights but there is more risk. By doing so you are adding more things to rely upon to have an uneventful flight. This post is just thoughts I have and not here to start any arguments. Your thoughts. I wouldn't mind upgrading to a more sophisticated bird but if all the extra things I have to worry about like software glitches, NFZs, etc take away from the reliability and enjoyment I have now, not sure it would be worth it to me. My birds will not last forever and at some time I will have to get a newer model. I just like going out to fly and not have any problems.
