Hi All
So I've just recovered this data from my SLCF after flying a CTI K740 load over the weekend, and I'm looking at that sudden drop in the red (velocity curve) which more or less corresponds to motor burn out for that motor (2.5s) but also the small smaller corresponding little glitch in the magenta (altitude). Is this a Mach pressure drop? The rocket simmed to M 0.97, and an altitude of 7648', but the actual altitude recorded is 7947'. So I'm wondering whether this indicates the rocket passed through Mach 1? Screenshot below. Does anyone have any Mach + experience with the SLCF to compare?
Thanks!
