Decaff's YSFlight Tools
YSFlight Pack File Reducer
This tool will help you reduce the size of your pack when you have many models with many common components. I used this to great effect with my F-35 Pack v2 where I reduced the uncompressed size from over 200mb to 81mb. You will need Python 3.x to use this tool. Please read the accompanying documentation as you will need to edit the code slightly for your specific files.
A Python tool to help modders collect raw flight data from a .yfs file and convert it to a readable .csv file with appropriate header information to facilitate DAT file optimization. You will need to install Python 3.4 to use this tool. Please read the accompanying documentation for help understanding the raw data values produced by YSFlight.
YSFlight Flight Data Recorder Tool
A Python tool to help modders perform quantitative flight test and data review of their aircraft. You will need to install Python 3.4 in order to use this tool.
YS Flight Log
Save your server flights and extract a log of your flights or a combat summary. Check out Decaff's personal Flight Log from the Civilian Aviation Server for an example of what this can look like. Download includes a log compiler script to help compress multiple Flight Logs from many replay files.
A Python tool (written in Python 3.4) that reads a YSFlight Scenery file (.fld) and detects VOR Ground Objects. It then generates an HTML file that provides compass headings and distances between each VOR. A sample output can be seen here.
