Hooked,
Congrats on getting a Sig Pig. I'm on my third one. You can find my current Hog Bipe on page 5 at fubarhill.com (plus in my avatar). All of the mods you suggest I agree on with the exception of modifying the tail feathers and the turtle deck. I threw away the plastic turtle deck and carved one out of a balsa block, which makes it easier to cover (not paint). One mod you didn't mention is to do the dual aileron mod. This is a huge mod that you need to do to eliminate a flutter problem that can occur from having just one servo. Other than that this kit a dream to build and a fantasy to fly!!!! I love em.
