Update of /var/cvs/FlightGear-0.9/data/Aircraft/dc3
In directory baron:/tmp/cvs-serv13750

Modified Files:
	dc3.xml 
Log Message:
Give the hstab a negative angle of incidence (as is normal for
non-aerobatic planes) and move the CG back a bit.  This eliminates the
tendency of the plane to noseover and crash during takeoff and landing
rolls.
