Thanks Sluf7,

I'm have'n a very good time with this airplane. Might be going a bit overboard with the engine cooling. The guys at Revolution Engines told me to make sure I had air directed around the cylinder......... so that's what I'm doing.
Fabricated the rear engine baffles and made use of the 10-24 threaded hole in the middle rear of the cylinder. The cross brace center is just a 10 size 1/2" unthreaded aluminum standoff that I laminated a bunch of fiberglass and carbon tow to. still have some triming to do on the right post mount ( the band saw should make quick work of that once the epoxy sets up). The whole assy will get a coating of BVM heat shield (water based ceramic coating - http://bvmjets.com/Tools/heatshield.htm )
Also a shot of the completed fuel tank assy.
