Dave,
I see. This tells me a great deal. You're building contest grade models.
My guess is you've fine tuned construction and assembly methods in many areas.
I must admit, this level of building is a few octaves, many actually, above what I do. I get it done but cannot use words like superior.
Congratulations on you'r efforts, you're brother also. You're work is superior.
I might camera drone outside your shop window. Pick up some of your building skills.
