Ouch.
Not my best day out on the field! My L2 failed to deploy the main, which I now believe happened because the battery holder might have broken free of the sled at the drogue charge and been disconnected by the movement, preventing the main charge from firing. That would explain the lack of event and also why the altimeter does not appear to have recorded an apogee altitude. This didn't happen during the ground test, but maybe the holder was loosened by the ground test and broke free now. I tried to take that in stride and fly my other planned flight, but with that flight I had the opposite problem and my main came out with the apogee event. I ground tested the rocket without paint, so maybe the amount of shear tape that worked then was not correct for the now-smooth surface. In any case, the rocket drifted much further than it did on a previous flight on the same size engine, and though it looked like it landed in a recoverable spot, an hour or so of searching came up dry and I am now down a rocket, casing, and altimeter. If anyone finds a 6' long yellow and orange rocket somewhere near the peas or the swamp, I would be very happy!
On the positive side, my L2 rocket is not damaged except for a few cracks in the paint so it will definitely fly again in the fall, and I got videos of many liftoffs with my GoPro that I left by the HPR pads. I will be cutting that down and uploading it soon!
