Using OSG cvs version, updated yesterday.

I got from CVS - great model, but I seem to have an issue.  After taking off, 
I can fly with full throttle and slowly climb - but if I knock back throttle 
I seem to loose everything, and the aircraft just slows down and gently drops 
to earth in the horizontal postion (i.e. it doesn't crash, just floats down 
like a feather).

I see this in the console:
