Coming from 3D helis I like flying a bit of acro with a Gaui quad with a cheap piezo FC and switched to MultiWii (in AlexK mod) recently. In both setups, the standard acro stuff (loops, rolls, turns, flips) works pretty well so I tried it with my DJI F450 and APM 2.5. Every time I ended upside down in the loop, the quad simply stopped there, refused to proceed with the second half.
ACRO_BAL for roll and pitch is set to 0, ACRO_P to 8. So the quad reacts pretty fast, but there is still no way to accomplish flips or loops. I deactivated AcroAxis, but no way, even slowly flying circles becomes a challenge!
This is no big deal because the DJI is actually intended for FPV, but on the other hand sometimes a little bit of acro would be fun either!
Really no way with ArduCopter?

My question has been answered in this discussion. In short: True acro flying is not possible at the moment with ArduCopter but work is in progress.
I hope final results will be satisfactory to skilled pilots, i.e. true and pure rate control. Just no rolling or pitching with sticks centered, rates simply proportional to stick deflection. But most important is the possibilitiy to switch off all the acro trainer and levelling stuff, that gives you the feeling of being steered by someone else! In such a mode FC has to control the copter in a way that it does what the pilot expects, not more, not less.
When you are centering sticks with the copter being upside down it has to fall!
It has to fall until your sticks tell something else without any rescue function (well, switched would be ok) that may improperly interfere the communication between pilot and the copter at the wrong moment.
Shortly a guy named Alex Khoroshko implemented some modification to the MultiWii 2.2 code. Until then I couldn´t find a better acro FC than a simple piezo KK5.5. Now MultiWii is even better!
