Total Bits = 9 + 12 + 12*3 + 9*3 = 84 bits = 10.5 bytes = 11 bytes11 XX
XX bytes at 5 Hz = 55 Bytes / Second
128000 Bytes 1 MegaByte / 55 XX bytes per sec = 2327 seconds = 38.78 minutes of data
Ideally, there is a rolling buffer of data, waiting for takeoff. Once takeoff happens, ignore / erase the previous data aside from maybe 5 seconds before
