It's the CG being to far aft. I have shifted it a bit to the front and now it stays on ground with elevators neutral up to 150 kts and above rises gently. It seems as if there were too many fuselages in the rear, I had to remove the vstab mount fuselage definition to get it reasonable.
Hi, great! Now it seems to go much better. At least that's my first impression, I have yet to try a little more (Edited: on empty fuel tends to nose up

Usually I don't mind a positive Cruise AOA.
This was to facilitate the management wing leveler before becoming available on autopilot, so it's no problem to change.
add this to the <hstab> definition to have the gload limited to approx 9g
Thanks, I had not found this option yet. The response of the aircraft is stopped when it exceeds the ceiling, which gives rise to jumps when we try to exceed the limit. I think it's pretty good:) Anyway I was now used to manage it without limitations, I am going to miss it

Best regards.
