Resolve Mantis 6480 (http://opensimulator.org/mantis/view.php?id=6480) 

by reversing the sign on the recoil computation and adding a
[XEngine]RecoilScaleFactor parameter which defaults to zero.
Testing in SL seems to show that there is not a recoil action there.
Or, at least, it is very small. If someone knows how small, the default
for the scale factor should be changed.
