Ed,
Sorry, you must have misinterpreted my inputs to this thread as me expressing an interest in designing and building parts as a commercial venture for your A-6 project.
As I said in a previous post, I only build for personal pleasure, and I have no interest in turning any part of my hobby into a commercial undertaking.
While I am happy to provide suggestions to enable you to think about how you are approaching the A-6, I will not be taking on any part of it.
Wishing you all the best
Paul
