You guys crack me up!
First it´s "The plane is falling to the ground, I can´t keep the nose up, help help help!"
Now it´s "The plane is floating, how can I get it onto the ground? Help help help!"
I personally think the plane flies a lot more realistic (with regard to the flare) in 11.30 - and I can land it just fine. So I would say get used to the new dynamics. The only thing changed was the force needed to keep the nose up - no changes to wing lift, ground effect etc.
Can´t say how the Zibo flies - and I couldn´t say if it is realistic or not, as I have never flown a NG. That is for Zibo to determine.
