Hello IBob,
Thanks for getting back to me. Yes, I can fabricate them using his experience, particularly regarding the size of the curved lexan on the partial upper panel. But, if someone had sketches, notes, and general advice regarding their experience, it could save one a lot of effort. I enclosed a couple of photos of my attempt at making a 3-point door closure mechanism, the idea was from a photo of a Savannah I saw on Recreational Flying. After a good week of making a lot of parts that didn't fit, I finally got something that works quite well.
I decided to keep the kit supplied Dzus type cowl latch in place--you know, belts and suspenders:-)
