[FIXED] Absurd Pitch Behavior

[Get_Lo]

Been experimenting with the Mirage's pitch behavior and ive noticed some interesting trends when you go heavy on the stick, such as being able to rotate the jet all the way to and beyond -180deg of AoA. it can be done with the pitch damper on aswell. Cant lie, its been pretty funny but I figure the devs would appreciate the information.

Trackfile demoing the problem below.

That... is one of the coolest DCS videos I've ever seen! Nice work figuring that out. I wonder if its related, but I have had the Mirage F1 push through its drag (it feels like) when applying full forward stick for a long time. If done at less than about 350 knots (so the pilot doesn't die) the plane will eventually begin to GAIN energy while at a high negative AoA and the engine eventually dies due to the negative G.  I could sometimes keep it going past engine death.  Have you noticed anything similar in the F1 yourself?  If I remember tomorrow I'll attempt it again in instant action to get a short track to post.

I have actually noticed that past a certain negative AoA you start to gain speed again. but its quite far like you said. you can actually see it in the Tacview in the YT video above

Oh you are correct, I do see it in your tacview! So the issue is likely related to some FM calculation that breaks past a certain AoA and allows all the crazy stuff, very interesting.  The funny thing is the plane feels extremely convincing otherwise until you take it to that limit.

I tried several tailslides today and I found out the airplane will pitch over (down, FWD) rather positively when getting slow at the top of the maneuver. The pilot has no control over it and a stick fully aft won't help at all. I'll have to do more testing, but this seems related.

It's the french special inverted cobra , gen5  fighter pilots are jealous of it ..

This plane is very wobbly, I thought the Mig 21 was the wobbliest plane in DCS. But this one is hard to get a kill with guns, almost impossible. This plane is in the early release state and understandably, needs more polishing. Hope the FM gets more priority on refinement. Mig 21 is controllable to get gun kills.

Because obviously many still haven't noticed:
