after having bothered the forum for quite a bit and quite some issues setting the copter up (took months, before it worked), many many crashes and broken equipment, i got one arducopter flying. - Unfortunately not for long as it shortly after crashed due to unknown reasons.
In the end, i decided to buy a Naza + GPS and got if flying straight away, even with different ESC, Motors, Prop's, Battery and heavily modified frame.
Naza setup and operation seems so simple to me that it's just a breeze after the issues with Arducopter.
However: I still like arducopter a lot and would prefer to use it over Naza - it offers a lot more flexibility and i just like the open-source approach.
Now, my question is:
Why is it needed to so heavily tune and configure PID's - Lot's of them - even for different flight modes etc. - while Naza simply has 6 gain settings which even work out of the box with the defaults great - with some very easy tuning (without risking or crashing the craft as on arducopter!) working even superb.
Is it maybe possible to implement this kind of control (no idea what they use, maybe self-adjusting PID?) in Arducopter ? - Or is this something which we maybe can have in PX4 ?
