I just got back from a flying session with it -
in doing rolling circles etc - where pitch is constantly changing -- the model will keep an even track -not pitch sensitive -
I had to increase expo somewhat to desensitize it - but still the ability of the wing to do this -PLUS offer instant flick rolls -which are totally predictable confirms my earlier thouht on this concept .
You an theorize till the cows come home - but actual practice is the real world.
The thick winged models of the same size /weight are terrible on the flick rolls - they simply refuse to stall.
