The only thing I would change is the plywood material I used for the "cuff".

When I came up with this technique, I always used unidirectional carbon fiber laminates (the 1/2" wide, .014" thick, rigid stuff that several people sell). These work OK, but are only strong in the long axis, so they would crack pretty easily handling the plane without the surface installed (which is half the reason for doing it, so you can get the plane all the way apart for painting AFTER you have hinged it)

Anyway, I tried that 1/64 plywood. It works OK (and very cheap), but it is not as temperature stable as I would like. Depending on your finish technique and paint color, the plywood cuff might get wavy in the heat.

The new stuff I am using is from Art's Hobbies. If you look at it, it has a bidirectional surface coat to it. This makes it very resistant to cracking. This stuff is perfect for this application, and I am using it on my new Super Bandit with excellent results. Everything else is the same as I posted.
