Fifth flight of the day for Slick Willy, 30th flight overall.  Pretty severe weathercocking off the rail, travelling horizontal at ejection.  Good drogue, wind actually brought it back pretty close.  Good main deployment at 500 feet, landed in a plowed section of the field with no damage.  I really like the CTI I-Max motors, but this is twice now I've flown this motor in this rocket and had it tip off pretty badly.  The thrust profile would lead me to believe that this shouldn't happen, but then again this particular rocket is definitely over stable.  I've got one more of these motors stashed away somewhere, guess I'll have to wait for a calm day to see if I can get a straigh boost.  Probably had time to prep and fly this rocket at least once more, but I didn't have nay more motors with me so this was it.
