    Wow, they sure look good to me !! Nice job on fabricating them !!
  4. Looks really good!!

    When I was researching P-51 for a display model I was building I remember reading a paper about the RR Merlin, and if memory serves the Stacks were 4 or 4.5 inches in diameter. Don't hold me to that though, I can't find the paper I read to check.

    I would be quite happy with what you have, it looks right on!
