+===== Logging =====
+Several bits can be set for logging of different informations: [[https://ardupilot.org/plane/docs/parameters.html#log-bitmask-log-bitmask|Log Bitmask Description]]
+Enabled all (''==65535'') results in following per message data sum in bytes for a 20 minute flight:

+The PID, NKF(EKF) and IMU take a lot of space.
+The PID and EKF is saved using the "attitude" bit in the logging parameter setting (see [[https://github.com/ArduPilot/ardupilot/blob/6af0f460afa6f51c41056cd25fe2c70164d9d460/ArduPlane/Log.cpp#L39|Code]]. For the attitude two settings are available: Fast (50Hz), Medium(10Hz) according to [[https://github.com/ArduPilot/ardupilot_wiki/blob/6c81c28126e6cb2bdbb9cb58291342ca3ade96a0/dev/source/docs/using-the-command-line-interpreter-to-configure-apmcopter.rst#reading-logs-through-the-cli|LINK]].

 For the Extron 800KV Motor , we have 14 Poles.
-After empirically comparing measurements of the given RPM sensor with some tachometer measurements, the actual formula need to be as following
-''SCALING = ( 1 / # of Motor Poles )''
