Thank you all, will try out all these recommendations when it stops raining.
My OP CC3D recovers from tilting over 45°, close to 90°. But it is a very light carbon quad and is more trimmed for fun flying and not to be a stable hovering platform or to fly missions. And of course you can switch off stabilisation completely to fly rate only, but that is not what I meant.
And yes, the word Flip in the name of a frame is not a good idea for AQ trying to be the most stable platform of all.
It will become a busy month, the new NAZA v2 FW is out and soon the OP Revo will be on it's way to Belgium.
My first impressions of the AQ are however quite good. It is very good on GPS hold even in strong gusting wind, much better than my MK ever used to be. NAZA GPS is almost as good, but the baro of the NAZA is still better although I must admit I've not been tuning the altidute hold of the AQ. I want the Rate D and Mixer setup to be perfect before tuning altitude. I like the logs a lot, something missing in many other platforms.
My only wish so far is to be able to read out the SD card without removing it from the AQ. I can't count the times I started flying without the card inserted because it was still in my PC reader.
My first quad was a Asctec X-BL that still flies well, but amazing how things have evolved since 2007.
Once again thanks for the help I get here at the forum!
