Hi James,

Well, actually, it DID turn toward the balloons, but I think it was a
conincidence(because the IR receiver was not receiving the target signal
before launch). I haven't had a chance to really go over the video frame by
frame yet, but I plan on doing so to determine the rocket velocity
(roughly) and how well the motion corresponded to what the fins were
supposed to be doing. I am not sure if the initial large left turn was
due to instability (too slow coming off the rail), or if it was because
it happened to be launched exactly when the fins were turning that way
(just because they oscillate back and forth for the conical scan motion).
Due to having large forward fins, this rocket is not extremely stable (I
did a static stability analysis and the CP is about 1.5 tube
diameters or so behind the CG)
