The data I have show flights at altitude tilting over right at apogee, which also surprised me. I don't have a lot of such data yet, only three or four flights. Which is why I suggest adding the combination of the accelerometer-based speed computation with a long timer. The good news is that at altitude, it doesn't matter when you put out a recovery system; it won't have any effect for a long time during descent given the low air density. Waiting 20-30 seconds after apogee works fine. -- -keith
