Hoverfly V4.6.r2 and AH gain

I know some discussion has been done on this before but i can't find the posts...
So i updated my X4 to V4.6.r2 and fly today in a very calm weather. The flight is just great, very stable. For AH gain i had to lower it to a very low value of 2% ... I am using a new Graupner MC20 Hott. With this value the altitude is hold very well but sometime the craft starts to descent (after a yaw action for example) and it's necessary to bring the throttle stick up to get the ship moving up...
Two questions:
Is it normal to have this so low value for the gain?
Is this instability in altitude is a gain pb, and what to do to lower it more (i believe the limit should be 1% .. Is 0% allowed?

That's what mine does. Guess ill have to try the super low gain

Why doesn't this work on many hfp boards.

HF have said that you really need to be level and hovering at a stable altitude for AH to work with 4.6.r2. I did get an ok hold at 2% too - so I know what you are seeing. I tried all the way up to a high number and got quite a mixture of results. I always climbed to 50' so I had room for it to drop and stabilize.
After two flips (and $2k) on two machines with 4.6.r2 that flew really well until 4.6.r2 decided it didn't to behave, I rolled-back to 4.3.802.
I'm back to having good flying and a good AH. I haven't tried 4.6.r3 yet.

Do you know why it flipped?

No.
My Droidworx hexa had 60 minutes of testing with r2 and I was finishing a shoot over a road. I was in AL for a VERY SLOW descent from 200' and a small thermal hit at 15' up and it start to pitch oscillated - until it flipped (smashing the RX100 camera + half the machine).
My quad was also flying with r2 in manual mode in some 15km wind and while descending forward, it oscillated and flipped.

HF say that there "may" have been a problem with r2 which is why they made r3. I did nothing wrong and lost $2k. Frankly, if HFP didn't fly so damn well on 4.3.802, I would have binned them but when tuned with good firmware, they are awesome.

Ok so i'll be using my "teacher" quad to folow/test the new release and stay with 4.3.802 for the "big" crafts until it's safe to update...
By the way i made a mistake and i'm running r3 by now on the quad.
