Hi All,
I've been building and flying a standard configuration quadcopter with 13" frame and multiwii 328p controller. I've achieved a fly-able level of stability, but want to explore ways in which I can improve the performance in terms of stability.
Firstly, is it possible to achieve "super-stable" flight, in terms of position hold, roll, pitch, etc., through a stock FC such as the multiwii and its PID inputs, or would it need a unique FC with faster response and tailored programming?
An example of "super-stability", I guess could be like the quads in the ETH Zurich project:

They seem to achieve a perfect hover and precise manoeuvres, but it's not something I've seen in many hobby applications using standard FCs. I understand a lot of computation is carried out on externally in the ETH project, but I would presume stability is all handled on the onboard FC..
If any clarification is needed, let me know, as I'm still relatively new at this. And my background is aircraft systems design engineering, so I'm lacking a little knowledge in the control department, although trying my best to learn!
