Introduction & Installation

IMPORTANT - The BFF Control Loader software operates with BLDRV-12/24 brushless motor driver cards in properly designed and built simulator flight control systems. Before using the software please ensure that your BLDRV-12/24 drive system has been properly set up and commissioned, and has been tested using the BFF Driver Test application in accordance with the project instructions. For details of the project documentation see here, and for details of the BLDRV-12/24 cards see here.

The BFF Control Loader software runs with MS FS9/X (also Lockheed MartinŽ Prepar3DŽ) and X-Plane v10+. There are separate versions of the CL software for MSFS and X-Plane; both versions are included in the download zip archive.

The BFF Control Loader software consists of two separate applications. BFF CL Settings is used to configure and save configurations for individual aircraft. BFF Control Loader is the control loading driver software.

Installation is simply by unpacking the contents of the Zip package into a dedicated folder on your PC. The software does not write any values to registry, so to delete the software just delete the installation folder. Run the programs from this folder, or create shortcuts which point to the folder - DO NOT remove the files from the folder to run them.

If you are upgrading to a more recent version then do not mix the files of the new and old versions. Unzip the new version into its own folder. Then copy across your old Pry_S.cfg file and your working aircraft .cfg files to the new version's folder. This will carry across your current configuration. You may need to manually add to your cfg file parameters needed for new features - check the description of the new feature in the online guide. 

To use with FS9/X or P3D, FSUIPC needs to be installed. Use the latest version and follow carefully Pete Dowson's installation instructions. See

To use with X-Plane, XPUIPC v1.9.0 or later needs to be installed and a customised XPUIPC_offsets.cfg file copied to the X-Plane XPUIPC folder. Follow the instructions in the XPUIPC documentation. See also section 6 for other important information. See

NOTE for Windows 7 the GUI text may not display properly if the desktop text size is set to larger than the default 100%.
