I flew Disappearing Act yesterday for the Tripoli I record on an I59WN. Disappointingly, it weathercocked a lot and only went ~10247 feet. Oh well, there was no record before.

Things to note: When the rocket went supersonic (1117 ft/s at 60 F), the pressure
decreased instead of increasing, then increased again once it slowed down. You can see this in the comparison between the baro and accel altitude traces. The single vent port was just behind the rather blunt nosecone, but I'm not quite sure why that would have happened.
This time, I sealed the av-bay with putty, so there were no odd voltage happenings.
Also, this I59 was incredibly noisy! The only other one I've seen made a wimpy hiss, but this one made a crackling roar as it ripped off the pad. At the burnout of the boost White Lightning grain, there was an acceleration spike visible in the accel trace, and which you could clearly hear on the ground.
Then, I flew it on an Aerotech I1299, for a predicted 220 G's (with a 250 G Raven). Man is that motor ridiculous.
Unfortunately, it disappeared and the tracker put out no signal, so I haven't found it yet. I would really,
really like the FIPa file from that flight...
