Phewww! All the heavy duty carving, hollowing, and sanding is done! It's finally starting to look like a Mach 1. There has been some talk about using the OS AX .55 in the Dirty Birdy threads. The AX .55 along with a Performance Specialties muffler is what I plan for this one. The fuselage as you see it weighs 15.2 ounces.
