Really to the extreme that the KETanas show or just slightly like many other G3 planes? I mean did you actually have a look at the KEtana?
I sure did.
If anything the KEtana behaves much more like my REAL Funtana 90S now, far better than before.
On my Funtana 90S I have to keep the high rate throws to under 40 degrees to prevent this, and yes even at low speeds.
40 degrees is quite a bit of deflection on these huge tails.
Of course you want as much as possible for hovering, so I end up leaving the rates around 35 degrees for high rates and down to 15-20 for normal acrobatic flying.

Hm, I agree that stalling of one wing would be an explanation for what I observe.
Then again, the behaviour seems to be more or less independent of speed. Actually it can be reproduced at very low speeds as well.
I also wonder why this happens to such an extreme for the KEtanas while it doesn't happen for other (stock) planes.
Basically the size of the tail.
The bigger it is, e.g. the more area it has the more pronounced this occurs... much like real planes.
That big "wing" at a high incidence stalls out along with the reduced effectiveness of the main wings causing a roll to one side.
Change the wing loading and right thrust and you can reduce it though.
This really threw me on my Ultimates because everyone said that it was a lateral imbalance at first...
On RCU I pointed out that the same model in G3 also exhibited this behaviour and that you could fix it by lessening the throws.
The light bulbs seemed to go off for everyone then, and now the first thing the participants tell people now is to, lessen the throws but also check the lateral balance....

Indeed it doesn't seem to happen with low rates.
Don't get me wrong: I didn't assume that this was a problem of the flight model, I just thought that this was a strange setup for a stock plane. With a plane becoming almost uncontrollable so easily, I guess not too many people would be happy.
Try this, change the percentage for the rates in high rate mode, in the software radio.
Adjust it down until it stops happening.
You'll find that this will still give you enough authority for hovers...
But basically the KETana has the wing loading a little high.
I THINK that G3 is reporting the total wing loading for ALL surfaces including the tail.. so it's not reporting the actual wing loading for the main wing...
That 16oz wing loading is much higher, so the plane has more of a tendancy to do this.
If you increase the throws and loading on the model of the Funtana 90S you will attain the same behaviour though.
