Yeah I am working on it, I got a little annoyed with this plane with its patchy stability during the beta updates!
I can tell you directly the problem in the flare, the way the tail is currently modeled is like a 172, where there is an elevator and a fixed portion of a horizontal stabilizer. Like this
However, the way the tail SHOULD be, is an ALL moving stabilator where the entire control surface moves and deflects with zero fixed area. Like bellow
So you can imagine the difference in just modelling the tail wrong like this, it would completely remove maybe 40% control authority (or some other random number who cares). The point is, its fundamentally designed wrong in the simulator!
So in summary! Yes as soon as I find its stable and my Xplane 11 doesnt immediately crash when loading I will have a model for it. Its a fantastic looking aircraft I know that much!
PS: Are you asking for the model in XP10 or 11??
