Very new to the hobby. First time building a drone, I built a Hex running a pixhawk4 mini. Last year I was unable to configure the mini with arducopter. One verson didnt recognise the transmitter and another version wouldn’t allow compass calibration. Eventually I gave up and flashed a px4 stack and configured through qgroundcontrol. The craft was almost unflyable, it pitched and rolled about violently, after days of PID tuning it was almost controlable but still really twitchy to fly. So the craft did fly several times.
I have wanted to include telemetary so when the new 4.0 ardu stack came out I immediatly flashed that to see if the configuration problem had gone away. Happy to say the 4.0 stack flashed easily through qgroundcontrol (Did not try through mission planner in the past that has not worked).
After configuration a short first flight made me land and seek out how to decrease the throttle and alter the hover point. The auto hover point from flight in alt. hold prompted me to configure modes to stabalise and alt hold. After flying in alt hold it appeared the hover throttle point had moved and it was closer to mid point on controller. Battery beeper activated and I statred to very slowly fly craft back towards me when it violently flipped and crashed. I assumed a low battery problem but checks suggest the buzzer activated correctly and there was plenty of power to fly it back.
Replaced damaged bits and decied I would try an auto tune immediatly to get it as stable as possible.
Launched in Loiter and switched to auto tune (auto tune as mode). After 5 minutes of tuning the craft dropped. All motors had stopped and it just fell down.
Restarted to see if things were still going and everything appeared fine. Launched and hovered in loiter about a foot off the ground. After a couple of minutes its suddenly flipped over very aggressivly. As if one side had shut down and the other was full throttle.
Does the community have suggestions where to go from here? I dont have logs but that will be my next learning. I cannot rebuild it now so further testings is a long way off.
Does anyone else use the 4 mini and been having issues getting a hex flying? Or could someone make a suggestion on which fligh controller is better?

I have a s500 quad running the great apm2.8 actually it was the first quad I ever built, still impressive though aged 5 years. I decided to build a new one using the pixhawk this time , I already buyed one and flashed it just to check if its working… I was opening the mission planner I use the mission planner 2.0 by micheal obams it gave me an update note! I updated on one of the two laptops I have but kept the other older version of mission planner 2.0 on the other and even an older mission planner 1.8 I feel I may need all, but I intend to use telemetry in this build.so I cannot get away with this two laptops thing… my question is what if I put three versions of mission planner on same laptop, any troubles may occur ???
