i noticed that on the f16 the speedbrakes have no effect at all and i
managed to track it down to the fact that the various coefficients use
fcs/mag-speedbrake-pos-rad on input which never gets set anywhere (so
it is always 0).
digging through the cvs logs i found that in version 1.17 of f16.xml
the output of fcs/speedbrake-cmd-norm used to be fcs/speedbrake-pos-rad
and it was set to 1.05 (which would translate roughly to 60 degrees).
so i tried applying this patch:
--- f16.xml 18 Jul 2008 14:41:41 -0000 1.50
+++ f16.xml 31 Jul 2008 20:22:09 -0000

now the various coefficients change when i activate the speedbrake but
there is still no noticeable effect on the plane.
does anybody have any ideas how to fix the speedbrakes?
