Jim, you don't have to do the physics for a 1 g roll. click on

stanford.edu/~sigman/one_g_roll.html for a really neat analysis.

Page down toward the end of sigman's article to see the actual flight

Oh, for the nonbelievers in Newton and vector analysis and such (Mx
whatever comes to mind) don't bother.
