Hello @ZenMusic2,
I"m afraid that I even don’t have enough time to build my own stuff 
Also be aware that my modules are based on the PIC-microcontroller and communicate with MSFS through my propriatery communication tool (see here), so not sure how useful this would be for you.
But I’m thinking of offering all files and designs for a small fee somewhere in the near future. This would include all the drawings, 3D models, schematics, etc… Would you be interested in that?
