+          This sets the space (in kilobytes) allocated for each flight
+          log. The available space will be divided into chunks of this
+          size. A smaller value will allow more flights to be stored,

+	  During ascent, TeleMetrum records barometer and
+	  accelerometer values 100 times per second, other analog
+	  information (voltages and temperature) 6 times per second

+	  The default, 192kB, will store over 200 seconds of data at
