I had an APM 2.5 on my plane for a couple of years and after the initial setup it performed reliably for those 2 years and was quite solid. Recently I decided to upgrade to the pixhawk and ended up buying two of them for two different planes. So far my experience with them has sucked. One of them died with the (No PX4IO board found) message which indicates hardware failure. 3DR agreed and replaced it (but it took a month). Now, just today the other one lost it's USB port and it's hardware failure as well. This is devastating to me and has me wondering if I should just give up on Pixhawk and just us the Eagle Tree Vector instead which so far at least has been easier to setup and with no failures ( I have two of them as well).
Though I'm intrigued by some of Pixhawks advanced features and capabilities I really want something rock solid and usable. But I'm upset that I've wasted about $800 and countless hours on this experiment. Did I just have really bad luck with this hardware or is it a poor design and fragile?
Thanks for any insight.
