..the real thing does this too.

..how much?  As much as the real thing?  AFAIK, the elevators 
bangs less an inch or so, around 50(?) times a sec, and should 
appear to see airflow head on(?), and alway below the elevators 
own stall angle to avoid a "departure", an unrecoverable spin, 
tumble etc, those has claimed a dozen or so F16's.

..another question, is how much slapping do _we_ wanna show? 
More slaps than the framerate allows, won't be shown, so one 
idea could be "just show the last jerk when the video is ready" 
for every frame.

..without a flight control computer (FCC), correct, it slaps air around 
to keep the plane under pilot control.  Orville and Wilbur also did 
this on their first few planes, and learned the hard way pitch stability
is a good idea when flying around without a FCC.

  Scenarios always come in sets of three: 
  best case, worst case, and just in case.
