Some modelers do have some great talents when it comes to construction of stunt planes. There are lots of 'How to' articles on just how one person does these things. My thoughts are; "Why just tell us how you do it. Why not give us some purchasing information and you can manufacture these parts for us." Hmmmmm, then we might get into the old BOM thing. I personally enjoy scratch building from plans or just out of my thoughts. Little pieces like cowlings, canopies, and wheel pants, would be great to be able to order by mail.
