You just *superglued it to a fin*!??
I wouldn't have thought that would hold up at H-motor speeds, never mind the crazy speeds you manage to hit. Clearly it worked though. I'm losing track of how much stuff I've learned from this one thread, I can't wait to see where you go next with this project.
I was expecting not to get the camera back, but my experience is that these upward-facing videos can be pretty interesting. It actually turned out to be very hard to remove the camera. When I pried it off, it took the paint with it. Although I got the electronics bay back, my little quartz window was broken, and that managed to damage the camera just enough to where it is no longer usable. To bad. That camera took some interesting (re-posted for the nth time) videos. RIP.

The quartz window has been fixed and the camera can be replaced.
When we were searching for the parts, we were not able to find the stabilization section. We had literally given up the search and were heading off the Playa when my wife spotted it. As it turns out, it survived the collisions and the fall (it's a tank). That's good, because it would not be trivial to replace it. From the on-board data and from other data, we learned that the stabilization system would probably not have worked had it stayed attached to the sustainer. When the booster spit the grain casings, it induced a turn that exceeded the gryo maximum. Since the rocket had a slight tilt at that point, it would have probably caused the sustainer to cone during the coast phase, which probably would have resulted in exceeding the tilt criteria for the flight. We are currently increasing the span of the gyros to allow 1000 degrees per second maximum, because it seems like there are too many things that happen with rockets that can cause the gyros to see short-term values greater than 500 degrees per second. There are some other upgrades as well, such as allowing the gyros to drift-correct right up to the launch point. I'm working towards testing the revised system in my two-stage "test rocket", with no sustainer motor, sometime in the next few months. I think Marlin would let me do it at Asa.
After that, I have no firm plans. I'd love the try the two-stage flight again, assuming it could be approved (it's just a matter of time, I think, before it will no longer be permitted). I'd need better leading edges for that, and there are some possibilities floating around there. Or, maybe I'll try a three-stager?
