Bigbry:

Incidentally... there was a similar request at avsim by the same poster in the previous thread I linked to.  Here's the thread:

http://forums.avsim.net/dcboard.php?az=show_topic&forum=121&topic_id=280355&mode=full

The question is asked on Page 4 of the thread, and some pretty good answers are given by a real Herk driver on Page 6 of the same thread.  Take a look.. I'm hoping some of this data provides you with enough to carry you forward.

Talk to you soon.
