Hi David,
Really nice CAD work on your updated Brushfire plans. Don will be producing a glass/foam version sometime soon, too. The original Brushfire plans resulted in a somewhat overbuilt (heavy) fuselage. I would guess an easy 6-8 ounces weight saving in your fuselage construction. I'd love to get a set of your plans as I have a Jett 120 rear exhaust which would be perfect for a slightly larger version.
regards,
will
