aoa limiter Can someone explain this behaviour? (Pitch oscillations)

[Lixma 06]

In the video I'm holding constant back pressure on the stick - the movement you see is not mine. I haven't touched any AP/Damper settings, so why is the plane doing this?

Go to external view while it is happening, and you can see why

The AOA limiter well move the stabilizer 2 or 15 degrees down depending on speed. When you are more then 2 degrees below limit the AOA limiter will shut off.

Thanks.

Thinking about it some more the 'bucking' is more to do with my joystick not being physically connected with the virtual aircraft. I guess FFB sticks might circumvent this; assuming they were powerful enough.

I had to make a different profile especially for MiG-29 as this behaviour would rip the stick out of my hands: it is that violent. So I see the exact same thing you do (as per your video above) even though my physical stick and the virtual stick are indeed connected.

I had always heard the real MiG-29 has very strong stick forces so it's not a surprise that my Rhino needed some toning down, or the overheat-protection would turn on even while doing simple free flights and landing practice

If only people flew the FC version of the plane, there would be like 95% less questions

I've been familiar with the behaviour of the Mig-29 since the super-sexy FM was introduced to the FC3 version, but I always thought the 'bucking' was simply down to an aircraft blessed with an excess of nose authority getting caught in a series of mini-stalls. It was only when I looked down yesterday and saw what the stick was doing that I realised there was another ingredient.

It’s also why a FF and FC level modelling of the very same aircraft can still feel very different even though they both use PFM: the impact of FF system modelling is not to be underestimated

But... there is zero difference? Or is that animation of a stick is of importance?

This is the "pitch kicker" designed to prevent inadvertent stall when the aircraft exceed the pitch rate or the AOA. 

Found in the flight manual, section AOA limiter.
