Richie:

Some simulation software can help:

Free demo of Rocksim at:

VCP at:

Richie--
I came on to this thread late...
go to http://www.apogeerockets.com/education/rocket_stability.asp there are
a ton of links that discuss rocket stability, some with ways to test
theoretically (see Ed's links below) and others to test a rocket already
built (ala the "swing test")  Lots of good stuff!

Richie,
I have great faith in WRASP.  I used it, exclusively, to determine the
stability of a semi-scale rocket with large, forward canards (Wasserfall).
Using the CP it calculated and making the CG 1 caliber forward of it, the
rocket has flown stable using a variety of motors.

I'd rather use VCP for my stability calculations... :-)

Oops!  Sorry for the braindead response.  Let me try that one again. I used VCP.
Thanks Robert.
