David,
All of these fillets are a buildup of microbaloons (brown in color ) and 30 minute epoxy. I have no bondo involved. I am goin about this very slowly. The area that is giving me fits is where the vertical fin joins the fuselage and those contours. I'll get there, I just do not know when.

I picked up a Don Lowe original Phoenix 8 this week. It was posted on RCU. I now have it in my hobby room and will work on it as a distraction from the radii issues.
