Multiple Session Support
Depending on the length of your modeling sessions, it is often possible to record multiple runs into the Recorder without
having to clear the buffer or overwrite data. The Recorder application will split multiple sessions automatically for you.
By clicking the “Sessions” option in either the playback or graphing pages of the software, you can display a separate
session, or all sessions simultaneously. When graphing all sessions simultaneously, vertical gray bars on the graph
indicate where sessions start.
Note that a new session is created in the logger each time it is powered off and on.
Saving Log Files
After downloading logged data, if you wish to save the data to play back later or to share with friends, save the file with
the File->Save Recorder File menu. Note that the file is saved with a .FDR extension by default.
Also, note that if you want to save only one session from the logged data, just select “File, Save Sessions” and choose the
session you want to save.
Graphing/Spreadsheet Compatibility
The Recorder application has extensive graphing capability built in. Just click on “Graph Data!” on the toolbar to graph
loaded data. Click on the HELP button on the graphing page for more information on graphing.
Also, the Recorder’s Data File is compatible with Excel ™ spreadsheet software, and perhaps other spreadsheet brands.
Using Excel™ is useful for graphing the data output from the recorder.
To load in Excel, save the data file from File->Save Recorder File, and in Excel™ choose File->Open, and select “All
Files” in the “Files of Type” box. Navigate the Excel dialog box to the location you saved the .FDR data file, and click
on the filename. Excel should then bring up the “Text Import Wizard”. Choose the “Delimited” option, and on the next
page choose “Delimited with Spaces”. The data should then load correctly in Excel.
The format of each line of data in the file is:
First Line: Model Name
Second Line: Data about your model’s setup, in an internal. This line is needed to allow sharing of your data files with
others.
Session Lines: The next few lines indicate the Sessions recorded in the file
Header Line: The header indicates what each of the fields represents. These columns will vary with the type of
Recorder and sensors used. Here are the parameters for the Pro, Flight and Glide recorders:
