I've been doing CAD design and I've been intimately involved in custom machinery building for many years. I originally designed these parts while I was building my Eagle, N216HP. Then another guy with an S-1S saw them and wanted a set for his Pitts. That worked out pretty good too, so I thought I might try to make a few bucks off of my efforts and help pay for my airplane habit. Feel free to contact me with any questions. I have installation instructions for the cabane fairings. Just contact me at email@example.com and I can email them to you.
Use these parts at your own risk. I make no guarantees as to their safety, but I can report that my Eagle flies just fine with them. If you buy, and you don't like how they fit, or just generally don't like them, contact me and we will arrange a return/refund as long as the parts are in resaleable condition.
